-lifter clip got past the pump-pick up screen? Man, that guy wins the "bad luck" award.

Had the same thing happen to me lost oil pressure and shut down engine.Took apart and spring clip was locking up pump gears and broke shaft. Had 3 let go sometime on a 6 hour drive. A lot of oil moved in that time and pulled the clip in. Shook my head as to what happened. Replaced clips and quick inspection and all good.

i cant believe that clip went all the way through the pump in pieces then through the filter, that is truly scary. that is a very good selling point for lifter valley screens.

I can’t believe I passed by your videos for so long, you are a Awsome teacher, so glad I subbed.👍🇨🇦

When installing the oil filter adapter make sure the part that has/had the bypass is away from the hole in the block ie 180° to how you had it while demonstrating.That way it does not block oil flow.

Just a little extra fyi to add to your great info, Rockwell used the same filter adapter in semi rear axles with inbuilt pump & filter for HD applications but were not machined for bypass so is blanked off, Baldwin B7 filter is slightly longer again which I use on my truck, keep up the great video's interesting stuff in a very easy to watch way

I just finished doing this myself, thanks for your help!

Never really thought about that if I’m honest. Rebuilding the Sbc in my sons 72 Ventura now and I’m definitely going to use this advice from now on…. Good on ya brother!! 👈😎👈

" Most spin-on filters must be used with some sort of bypass because they can't flow enough oil to handle 100% of the pump/ engine demand" Jenkins. The exception is AC 832 truck filter. Don't forget there is another bypass, in the oil pump.

I delete the bypass on all my engine builds and use a race filter because they don't filter down to fine micron ratings I change my oil more often but my SBC idles at 36psi fully warm and when I took off the pan last year everything still looked brand new with 110k miles on it.

I've always plugged the bypass on all my SBC's. I use straight 30HD and use NAPA's truck oil filters, part # 1794. It probably has a quart and a half capacity and it's length is longer but I've never had any ground clearance problems or blown out any gaskets on them. I also run melling high volume oil pumps. All on everyday drivers. I enjoy your videos.

I saw an urgent video about oil filter by pass so I jumped to your site as well I just cut open a fram filter for sbc and it’s just like in your video I am finishing a sbc re ring job so I got worried I plugged the bypass just like you did and with a better filter choices I feel confident sometimes you got to slow down and think it through keep up the good work

Wix and baldwin actually make the NAPA gold series of filters. My trucks are diesel , so good fuel filters are important as well as oil filters. Baldwin, wix and Napa gold are the filters I use on all my engines, unless , like the wife’s car, it calls for a specific filter from OE because of the weird new low weight oils. Even my harleys get good filters. Either OE or those 3.

I built a flat tappet 350 with a high volume oil pump. I had a rear main leak during break in. Figured I’d address it while it was still on the stand. Dumped the oil (with plenty of shimmer) and pulled the pan and main cap. The rear crank journal had light scoring already from only 25-30 minutes of break in. I could feel it with my finger nail. Checked a rod main just to make sure but it was fine. I put molly lube during the build and was how that journal could have been gouged. The high volume oil pump opening the bypass and letting unfiltered oil pass through, makes sense. Fml. Wish I’d seen this vid 3 months ago.

If I`m not mistaken performance filters have a courser medium in the vicinity of 60 nanometers where as a stock application is around 20 nanometers, much finer. If you use a high volume pump on a bargain filter with no bypass the filter can rupture or the element can be collapsed and cause loss of oil pressure, I use wix "r" filters in my shop on my track motors with no bypass and baldwins on the work vehicles and grocery getters. By the way I really like those 062 vortecs, I been hanging on to a set for myself that flow 244 @ .500. The napa filters are Wix

I am about to add oil to my new , for me , 350 Vortec , but first I will drop the adaptor and use the pipe plug >Thank You for the video .

Baldwin, Wix and Hastings are very good filters. Purolator filters are decent also. I use K&N filters with Mobil 1 extended performance synthetic oil. I have been running this in my vehicles for years and never had an issue.

Never had a issue on my sbc without a bypass running 15-40 shell Rotella in the winter it’s been down to -11 F where I live

I've heard from 2 other mechanics that fram filters killed 2 different engines. On initial fire up both had the same complaint the engine produced next to nothing for oil pressure and shutdown the engine quickly upon further inspection found that the oil filter imploded or sucked in the case to the core of the filter destroying the engine immediately.

You only loose one engine to the oil filter bypass valve to make this mod very very cheap. Somehow my cam and crank survived but the bearings didn’t. Engine had 300 miles on it. I Ran the oil filter bypass blocked on a big block on the street for several years with no problems. You do have to make sure that you have a filter that can withstand the additional pressure when using high pressure pumps and heavier single viscosity oils. Can’t go wrong with Wix. I’m sure there are many others that would be suitable. Cutting a few open reveals the inner construction methods used by the manufacturer. Asking the provider for information on what particle sizes it can filter out is also a good idea. Thank you for sharing your knowledge.

I’m definitely gonna look into this on my current rebuild. I may just leave mine as mine as it’s just a service vehicle and I’m running stock oil pump. I’d think that bypass would temporarily fluctuate open/ close all the time though if it’s 10-13 psi spring and most stock vehicles are running 30-50psi. One question I have is, do you use a gasket when installing the oil filter adapter?

You think if that motor with the clip that came off lifter if the oil pan drain plug would of been magnetic if would of caught it? I run a strong Derale magnetic plug on my new engines when I break them in and leave it there. I always ran the bypass and know what u are doing. It can get 20 below zero here in SD so I leave the bypass in place, I plug in my engines but the oil is still cold and if u block your bypass when the oil is stiff and cold the heavy oil can just bypass in and out of the oil pump if it has to much resistance being to heavy and can't go through the filter. Just a thought if u have thought about that? With the magnetic plug It will catch fine metal particles from a cross hatch cylinder breaking or camshaft breakin and u can clean plug and monitor things when u change the oil.

Great video for me an eye opener thanks I’m just DIY my sbc 350 and getting all the info I can thanks one question is the B6 filter for sbc? Thanks

I would run a much larger oil filter with more filter media volume.

I replace those cheap wire springs in the lifters with good C clips and use a screen between the filter and block and finally use magnets on out side of the filter or filters as well as auto tranny pan and I used a bolt and nut in the by-pass.the racing fram filters are good.i did see testing of filters on you/tube where they found that the k&n silver or gold was actually a smidge better than six racing but there are many that are more than adaquate,ac-Delo,motor craft,six racing as well as fram racing and GM has some qt truck filters like the Baldwin you showed and bigger.I’m running 2 right now with screens

if you do not have an external oil cooler should you have an oil filter bypass?

The most likely scenario is the clip was busted to pieces prior to entering the oiling system. If the filter used had poor filtration efficiency, something like a Wix XP which has the efficiency of a tennis racket, then pieces of that clip can (and have) go right through it. This problem is made worse when the bypass is deleted as that causes the pressure differential across the filter media to increase which causes the filtration efficiency of the filter to fall substantially. In testing a modified version of ISO 4548-12 (the standard for oil filter testing), blocking the bypass caused pressure spikes as high as 40 psi across the media (with a large Ford FL1A sized filter and 5W-20 oil, much higher with more viscous oil and smaller filter) and caused the filtration efficiency of a standard Wix to fall from ~90% @ 20 um to

That retaining clip for the plunger on the hydraulic lifter; my buddies engine had 2 lifters lose their clips, I found one on the valley & the other was stuck in the pickup screen. The break-in procedure was probably neglected & it’s my guess that the valve train was probably never adjusted properly or even at all.

I would rather have a differential warning than a bypass - maybe 15 psi, but setpoint depends on element used. Something like a 100 micron screen maybe make it 8.

When installing a Chevy style bypass clock the bypass to the outside of the block , your demonstration shows it to the inside. When installing a aftermarket oil filter adapter with out bypass ramp goes to the inside .

I may have missed it but that clip looks to be from a hydraulic lifter where it holds the inside tab of the plunger.

The bypass opens during cold start when the cold oil can't flow well through the filter. I've always blocked them. The filter itself has a bypass ability as well. The Fram part number is PH373, - easy to remember to cross reference to other brands. This one is the large high capacity filter. I use Fram for engine break-in as they are cheap and I'm just going to toss it soon.

Twice i have found a bypass stuck open. The first time there was a piece of nylon from the cam gear jammed in it ( a 1970 400 SB). The second time ( a 1988 350 TPI) it was just cocked and open. I could get it to close but if I pushed it just right it would stick again. I plug the bypass on all of my builds now. As far as ballooning a filter or losing oil; pressure during a cold start., the bypass in the pump should open preventing that. I have seen an external bypass on a diesel engine fail. This engine was failing and pumping garbage through the pump which stuck the bypass and plugged the filter. When the filter plugged, the pump and oil won, completely crushing the paper and center tube in the filter. Total destruction followed!

Have you tried swapping out the spring with a stiffer one?

I had rocker arm bearing clips break due to wrong clearances from manufacturing on my SBF. The pick up tube filter is crimped into place and has gaps all around which the clip went through. It took out my pump and then resulted in spun bearing.

Did you cut the pickup apart to see where it got through?

Carquest filters are made by Baldwin too, 85060 is the tall, 85061hd is the tall filter with no anti drain-back, and 85069 is the short, 2 quart filter is the 85794 and also has no anti-drainback.

I would think that oil control is everything. Also if you change the oil frequently with good quality oil, and a good filter Wix or K&N Gold series it should be fine.

I always use a filter Magnet.....

Fram filters are junk due to their “Core shift” issues. Core shift being the filter media breaks loose and restricts the flow of oil. Long/short circa 1992 I experienced a Fram core shift issue, how did I know? Because both Fram and Walmart admitted the core shift issue so I filled out my claim and submitted it to Fram. I had a fresh 357 SBC at the time; the core shift restriction caused the lifters to collapse! I wasn’t asking for a new engine, only a new cam/lifters but Fram never paid one cent even after admission of fault. I was a young guy in my early 20’s with no way to setup a lawsuit. JD

I use 15-40 rotella in my small blocks most are hydraulic flat tappet I have a vortec too, same oil and I use delco PF-932 filters on all of them, the big long tall filter, I’d never done this because I was skiddish that it would get enough oil pressure in the winter when the oil is cold. But I might reconsider that seeing this.

You can get that housing, without any provision for a bypass. It's a Chevrolet factory part, my 76' k20 4bolt had one.

Are we talking strictly built by pass filters or also separate by pass systems suck as Franz ?

I have a new car.. i was wondering how bypass works on cold starts... think i should get a early first oil change ?

I have A old 60s GM repair book and it says that the bypass only works at very low pressure 15 pounds

You are very knowledgeable that’s why I viewed. I’m building a vortec 350. But this I would not claim. That that clip went through an oil pump. Try it. Take a junk pump on engine on the stand. Engine bottom up. Cut pickup off. Put clip in with oil. Using a priming tool power the pump.

I was doing this in the 70's on my round track engines. I never told anybody about this. always use a Wix 2 quart filter designed for 366 Big Blocks log truck motors. Never had any oiling problems.

you should review the Fram HP series oil filters they seam well made, baldwin seams to be a great filter too..

Seen needle bearings on ford trucks get sucked up and chew up the oil pumps

Good deal

I have used gram oil filters for 20 years with no problems and I use it as a daliy

The adapter bypass opens when cold, and at high RPM. Any time you see more than 5psi drop through the filter its open. High oil pressure due to filter restriction is not good, most people check pressure after the filter, so they may not see the high pressure before the filter. You put more load (wear) on the timing chain, cam bearings, distributor drive gear, run the risk of shearing the oil pump drive shaft. Oil quantity is more important than oil quality thats why they put the 5psi bypass in em.

The same thing happened to me with the lifter clip on an old engine. I have real snap ring lifters now.

So you're saying the Baldwin B6 filter will work fine on my Vortec engine? Right now I'm running the Mobil 1 filter, and is the Baldwin the better filter?

Moroso 2 qt filter , personally I run wix on dailys , hotrods I use a System1 filter .

Many oil filters have a internal bypass just in case the filter clogs. I've cut many filters apart, if it clogs, you probably have major problems.

Fun fact. Wix makes filters for a lot of other brands. I know at one time Carquest filters were Wix filters. I believe (don't quote me) that Napa filters are made by Wix. I've never had a problem with Fram filters, but I went to Wix after hearing all the horror stories and seeing one cut open. I've always run a bypass, but you bring up a good point about bypasses and high volume oil pumps. I think I might start blocking the bypass from here forward as I always replace the stock oil pump with high volume even on stock rebuilds and even when just changing out the pan gasket or a rusty pan. Cheap insurance against a spun bearing.

Great video mate. Never understood bypass side effects till now. One question, I have a 87 Chev 350 single rear main seal with factory oil cooler lines. I'm removing all those cooler lines and going back to the Gen1 SBC oil filter style. There is some sort of thick adapter connecting the 2 cooler lines that needs to be removed. What do I need to buy after I've removed the cooler lines and adapter? Cheers

When the oil is cold and thick and or heavy weight oil will open the by pass until the oil heats up and thins out.

Did you remove the pressure relief valve is well in the block?

Are there different types of adapters or just one with and without the bypass?

Chinese lifters that aren't hardened are probably to blame for wiped cams more than break-in sequence.

I’m curious as to how improper break-in would cause that lip to come out of the lifter.

Somebody tell me what that aluminum pipe sticking up across from the bypass?

Hi thanks for the video. I have been having an issue with my sbc, 81 malibu w/ 350. The hot oil pressure drops to 12 to 15 psi at idle after a running it on the street for 20 minutes. I disconnected the aftermarket oil cooler to see if the improved the hot oil pressure at idle, maybe a small change but not much. My late brother did the build, I assume he knew his stuff but I cannot ask him at this point. Is the bypass always blocked when using an aftermarket cooler and filter relocate? I took a pic of the oil filter adapter but it is hard to tell from my pic. I was thinking of buying a new adapter from summit to see if it will help with my op. And did you say that there is no gasket there? Also, the rabbit hole that led me here was the question of oil viscosity. To go with 10w40, 30 hd or 20w50, seems like everyone has a different answer. And the best thermostat for a street beater, 160, 180, 195 or open. I am leaning towards a 180 to hopefully add a couple psi and trying hd 30 valvoline vr1 with a kn filter. I believe the block is a 350 four bolt with a single piece rear seal. They say my oil pressure is fine for that motor. I would like to see 25 to 30 at hot idle. So hope I didnt get to far off topic, they always act weird when I do that at aa...best. Ps, any advice on hot oil pressure at idle would be welcome,

You can also use A duramax filter on a small block. I run high volume pumps and always recommend them. They are almost identical size to the Baldwin in length. (About 1/2" longer.) And already have a bypass in them for more than what the small block normally has. And they filter well. I have run everything from 5w-30 to 10w40 with them. (5w-30 w/lucas and ZDDP additive) or 10w-40 with ZDDP only. And they do great. At least the ones I've recommended this to. I use & recommend this combo to quite a few people and most of these engines have already made it well over 100k miles; or about 170,000km and they run great. They are mostly mild builds (such as mellings mtc-1 & summits k1103 cam kits) with reasonable compression. 9.7-10.5:1. And I'm not sure that they all had the bypass removed as I never tore into everyone of them. But they do seem to keep oil clean enough.

Have a strange lubrication problem with my lifters on my CSB. Yesterday I began thinking about this bypass valve. I have just changed my lifters, pushrods and rockers. I took real care to make sure that everthing was clean. Adjusted them well. When cold starting the engine it makes a hell of a noise from the lifters. So I removed a valve cover and made a cold start. And there wasnt a drop of oil coming från the hole in the rockers. It took about 30 seconds for it to start to dribble a little and another 4-5 minutes before it was ok. When its up to temperature it runs smoth with no bad sounds. So my theory is that this valve is stuck open and when the engine is shut down every drop of oil is draing back through it, Basicly making every start a dry start.

I have a 95 trans am LT1 seems to drop oil pressure at high rpm wot pulls, also seems to have barely any oil in the filter between oil changes. Any input would be GREATLY appreciated. I bought the car done back in 07 I would assume the engine has been out as it is cammed. I tried changing the oil filter bypass and that did not seem to change anything. Have yet to put a mechanical gauge on it... right around 20 psi maybe a little less at hot idle 1,000 rpm. Any help would be great thanks!

Oil filters have built in bypass for cold weather startups.

No BS I’m in the middle of my cam swap right now and pulled the lifters out and one of them came out with that little clip missing. Hopefully it’s in the bottom of the oil pan ..

Run a good size magnet on the filter,or outer bottom of the pan..........you never know.

Where do they sell the baldwin filters?

You ought to do a oil filter comparison video.. wow have things changed for the worse. Some filters have been “discontinued “ and their “replacements” are way, way smaller.. like the old school long 2 quart fram PF-373... the replacement is At least 60-70% smaller. I wouldn’t have believed until they brought the replacement to the counter. Sad indeed.

I have actually seen an oil pump that one of these clips went through

Need a higher volume filter if you’re using a high volume pump or you’re going to run on bypass quite abit

Those non - by pass types are kinda expensive, about $40.00 from what I have seen. Nice to see a way to save some money and DIY.

I'm a little surprised the clip wasn't still in the lifter valley.

I had 6 of those damn clips break on me a couple years back, I put a new set of comp lifters in , no problems since , the lifters that broke were new , however not brand name, so I wound up blaming the lifters for being made out of Chineseium

I'm not a mechanic .... not smart enough to be but. I think if you in beef up your pump and don't change much else... pressure you'd figure would increase and the bypass has some sort of return spring. Calibrated * LOL ... makes sense to me as I'm looking at it like a pressure relief valve ... thanks for the video enjoyed it. Made me think lol

Oem puts a bypass in incase someone doesnt do regular oil changes and its better to have dirty oil flow thru the motor than no oil at all.

That's pretty bizarre. A little off the topic but this reminded of it. I bought a built 327 once from a personal friend and built by a local reputable machine shop. Started it up and was breaking it in when Kaboom ! Oil filter (brand new )blown off engine. The engine sat in heated house for 25 plus years. Has anyone encountered the same problem ? I found the answer after tearing into it.

Is it OK to have bypass after break in?

Power it through the distributor gear. If it doesn’t apple core it.

I believe oil filters have a built in bypass, that’s what the spring is for in the filter. Seems like the filter adapter bypass is redundant.

Fram oil filters are JUNK

Da grump lives on ! ( Lol )

I just rebuild my motor and I pulled out all of them little clips from my lifters are they supposed to stay in the lifters?

Do they have anything like this for a vortec 97 5.7

A friend of mine built an engine for his round track car it had 60 psi oil pressure he ran the motor 5 miles and changed the brake in oil, he put a new filter on it and filled it up with oil. the filter he put on there this time was a Fram. He started the car it ran five minutes and the oil pressure went to zero. I mean zero! I said that’s impossible you must have broken an oil pump shaft, the valves started rattling so we knew that the gauge wasn’t wrong. We pull the oil pan off and replaced the oil pump with an M 55HV. Put the oil pan back on it filled it up with oil started the car oil pressure went up to 10 pounds then back to zero. We put the old oil filter back on there just for the hell of it & the oil pressure went up to 70 pounds cold. That brand new Fram oil filter would not let any oil go through it and I thought the bypass had to be blocked but it wasn’t and I do not know why or how the oil pressure went to zero but as God is my witness it did and we fixed it by removing the Fram filter. I used to be a diehard Fram user never again will I ever use one!

I've run them both ways on my SBC race engines. I've also checked the bottom ends. With the bypass I would always see scratches in the bearings from debris. Once I started running it blocked, I don't see that. IMO, the bypass is there for people that neglect maintenance or everyday drivers that see extended oil change intervals. I don't believe they belong in any perfrmance engine.

You’d be surprised that the SuperTech oil filters are pretty good. Not saying you’d want to use them on a performance engine. *They are made by Champion Laboratories.

I run no bypass in northern Canada -40 400 small block 10 30 no problem WIx 1060 .. I build engines on a regular basis and they all get filter bypass delete

Wow, that guys is like me, if he didn’t have bad luck he wouldn't have any luck at all.

I always thought that shimmering in the oil of my newly built engines came from the bearing, tire my 355 down for a freshen-up after 7yrs of abuse and the crosshatch was still there.

Same here no bypass and have oil pressure in single digits with 10 /40 conventional oil

Gasket or no gasket Brother? Thanks

I've had 2 failures with Fram oil filters. They are junk. Luckily no harm. I use ac Delco or a K&N on my Chevrolet and a Mopar filter or K&N on my Dodge.

if you plug the bypass do you need a filter with a bypass? And does the filter need an anti drain back valve?

bypasses always leak a little, if they're poorly made they leak alot all the time. Ford hasnt run oil filter bypasses in their engines since the 60s

Hi I 90 1500 and I keep blowing my oil filter seal and the oil filter keeps cracking my oil filter adapter and I can't figure out why
