Crazy how that little o-ring causes all these problems. Thanks for the idea to check it out! Back up to 40 lbs at idle.

The video quality, lighting and amount of detail you put into this video is excellent. You simplified something that could easily turn into several days worth of work. Well done, and thank you.

As a backyard mechanic you are as thorough as any full time mechanic . You,ve included all the little secrets ,like rivets ,pickup tube screen ,o ring etc. Excelent job ,bravo on you .Thanks so much from another longtime backyard mechanic . Recently purchased a 2006 Avalanche with the same mileage ,this,ll help me a lot ,thanks a ton , a full time pro couldn,t have done a better job.

One of the BEST videos out there!! Very professionally done!👍👍Need to make more videos on other situations 🙂

I second the safety glasses suggestion. I've had dirt fall in my eyes working on stuff and it's hell. You increased the life of this truck quite a bit.

Hands down the BEST tutorial/ "how to" on the o ring replacement!!

Great video. I have a 2001 Silverado 1500 with 227K miles, original engine and transmission. I will be looking at my oil pressure more closely now. Thanks for sharing.

Very good video Boss.. I looked at many videos trying to find out what my problem was. Your video gave me good info & details about what I needed to know & answers. Very informative!! I appreciate this video & will be checking out more of your videos. Thank you 🤙🏼

Excellent video sir, I just completed this job on my 07 Silverado at 205,000 miles. Im pretty religious about oil changes and thankfully my oil pan was pretty clean, but the O Ring was flat.

Great video ! Awesomely explained and very clear viewings. You explained every detail very well. One of the best mechanical videos I've seen. Thanks

Thanks bud ! Best video I found on this, will be doing this on my truck this weekend ! 👍🏽

Best video on changing the pickup tube O-ring I've seen...doing it this weekend on our 05 Tahoe. Watched several videos and I think you're the first to prime the oil system (or mention doing so) before starting it up.👍

You my friend did a great video. You really were thorough with every step and the detail of the process in your video was 2nd to none. Kudos!

You put a lot of work into explaining and editing. You’re awesome buddy

Dropped the pan per your instructions and replaced the O-ring on the oil pick-up tube. Have great oil pressure again and my lifter ticking is gone! (2006 Silverado, 2 wheel drive} Thanks for the great video!

Thanks for the great video!, the oil will get sludge if a shop gets lazy and doesn't change the oil filter!!, had that problem, did a couple of engine oil flush, and it helped, been changing the oil more frequently, but going to replace the red O ring on the oil pickup tube as well!

Just got an 01 6.0L, this is the first thing I’m doing to it as it’s going to be a highway truck. Take care of them and they’ll take care of you!

I got a 05 Silverado single cab short bed that's black, love the truck definitely subscribed! Keep it up

Man, great video! Very detailed! You should've seen the Lm7 i tore apart that I swapped in my 83 Camaro. The oil wouldn't even come out of the drain plug! I had to poke it around with a screwdriver. Inside the pan there was handfuls of black oil jelly. It was horrible! It runs great, cammed with some other goodies and has almost 60psi cold and about 42-46 hot. Its horrible to see ppl don't ever change their oil at the proper intervals. These are great engines, possibly the best made of all time and if taken care of they will reward you for a long long time! Also, I always use the tall WIX filter as well. On my swapped 83 Camaro & on my 04 Tahoe & the part # is 51522. Cool to see that there's another tall WIX part # that also fits.....you used the 51045 right? Anyways great content!

I woud of just started the truck , im glad you did that oil prime ima do mine tomorrow just like that. Im changing the oring too

My trans is out for a rebuild. I'm taking the opportunity to change the rear main seal, barbell, and lift engine a few inches and pulling the oil pan for this o-ring/cleanup. hoping to lift enine and not drop front axle since trans is out:) Excellent video! Thanks. PS Thanks for the hint by a professional below to floor gas pedal upon startup as computer forces it to NOT start..and you can prime the pump!

Wow great video, I like how you mentioned even the smallest details, I definitely feel more comfortable doing it on my truck, thank you

I've always changed all of my vehicles oil at 3600 miles. A couple of years ago, i found out what happens when someone hasn't changed the oil for 2 years. I helped clean out the oil pan and engine that was just bad with all that sludge. Now for sure I'm going to continue to change my oil every 3600 miles. Once that oil becomes sludge and really thickens the engine is toast. Great info and Awesome, video.

Thanks For the Video! Just Changed the O-ring in my 2007 Silverado 4.8 liter (322000 Mile) Back to 40 PSI on cold start 1500 RPM Running temp 40 PSI / 26psi @ idle 800 rpm. But all lifter ticks and rattles are gone.. Would have changed the engine if I had not saw your video!

Awesome video. Great step by step directions.

Been fighting this tick/tap for a while. Glad I came across this video. This made the job easy. Pretty surprised how one o-ring can make a huge difference. Also went to an AC Delco PF61 oil filter for my 05. Taller than the original. I have better oil pressure and the truck seems to run smoother. Happy truck, happy owner. 300k and still going 👍🏾

Very good video my brother! I did this to my 2001and it gave me another 150,000 miles before tranny went out

Great video!! Was a little intimidated by the job, but not now. Question about disconnecting the coil packs. The mechanical action of the engine is the same when the pistons fire as when the don’t, correct? Are you doing this to limit the rpm’s at start up to prime the pump? Do you do this every time you change your oil? Just curious.

You did an awesome job. Your was video very helpful and very through! It took the job 4 hours to complete. My oil pressure was from 39# to 79# when it was completed. Thanks a bunch

Yep. Same on my 02 Tahoe 5.3, 274k mikes. Now 45psi idle and 55 psi, hot, 1500 rpm. Be sure to upgrade the pcv system (replace drivers side valve cover with new version w/better baffling and orifice). Oil consumption now down to~ 3k/qt.....

Were you loosing any antifreeze from your reservoir? My 2000 Silverado 5.3 was and I found out the heads were cracked letting antifreeze mix with the oil. I kept adding it but never saw any sign of a leak. my oil pressure went down like that because the filter would stop up with sludge. I replaced the heads and pulled the pan and there was enough of that goop in the pan that my truck would only hold 5 quarts to fill it to the upper mark on the dipstick. just curious.

Great video. that pick-up tube screen was a job for Brake-Kleen if I ever saw one.

Wow! Looks like a well seasoned skillet! Must change oil!

Video quality and your discussion were excellent:-)

Couldn’t agree more with all the comments, thanks!

I’m working on a Gen V L83 and suspect the same thing, except it doesn’t have an o-ring, it’s just the metal pickup tube into an aluminum housing. I suppose it’s supposed to be a tight fit but it’s got a couple thou wiggle room to it. I am curious if it’s the cause of my low oil pressure also. If an aging o-ring can cause aeration I am wondering just how little air is necessary to ineffectualize the oil pump ratio producing the target oil pressure.

Gonna be doing the same soon. Central Wisconsin I have a 2005 Trailblazer 5.3L with 228k. Still runs butter smooth however when it's freezing and below freezing the oil pressure drops. I've replaced the oil pressure screen and sensor however it drops quick when the oil is cold. Soon as it warms up in that cold it slowly drops if I don't have a rev up to 1k or higher. But when it's 40°F or above it's fine. Being that the fresh oil that is in the truck as I replace my oil every 3k. The pickup tube has to be the issue. The colder it is the harder it is for that oil to go up and if that o ring is broke or in the way obstructing it when the oil is cold that being the problem is the most logical issue since it runs and holds pressure fine when it's above fridge temp outside at idle

Brother you don't know how much you help me thank you so much I just subscribed

Did you use any type of silicone on the oil pan gasket when you went to mount back the oil pan

Thanks for this video! Just decided to replace mine and it was nice knowing exactly what tools were needed so I didn’t have to keep climbing out from under the truck. Also bumped my pressure back up to 45ish.

Hey Man, Nice Job. Keep up the great videos, Just subscribed.

You can buy the aftermarket oil pans with the oil filter relocation kit. I did this over a weekend and my pan had sludge all on the inside and full of coolant. Yes i did a full engine rebuild.

That was very Helpful...

Big dawg thkz for tha knowledge 💯 well explained and video viewing of wha 👌🏾 waz done ✔️ you learn sumtin new evryday 👍🏾🤟🏾

Nice video I'm about to do it to my 07 sierra classic just one question wouldn't it be able to be using water to clean those parts ?

best instructional ,video, lighting. speed and detail was awsome. best gm video out there.

Really good video. Very helpful. Thanks.

I've got the same truck except I have the crew cab. I installed a manual gauge on my truck and I have 25 psi cold. And hot is super low. I'm going to change the o ring and shim the spring slightly for my channel and see how that helps

Awesome now I know what I need to do for my 2000 Silverado Z71

Just replaced the one on my 05 Z71 worked like a charm. Idles at 40psi and runs around 45-50

That was a proper oil prime you did there.

Including the filter how many quarts of oil do you think you put in? I did this to my Silverado today and I got 40psi at first but then it dropped back down to 33/35ish when it warmed up. It got above 40 at driving and highway speeds but nowhere near 65 like you said ok your video when you were reving it up

I got a question hopefully you see this. Got a 2011 Silverado 5.3 with the DOD. I replaced timing chain and oil pump year or so ago. And now out of no where when I start the engine it goes to roughly 20psi, then starts to go down till 0 and the display says shut engine off low oil pressure. You can turn off and start right back up and it goes back to 20 then slowly goes down. The truck never knocks at all making me think that it does in fact have oil pressure. Would this be the oil pressure sensor/switch? The screen under it? Or is this a bigger problem

Awesome video 👍

Great video!

Wont disconnecting the spark allow fuel to spray still? Wouldnt just pulling the fuse to the fuel pump work?

Did the truck make a ticking sound prior to and after changing out the the Big Fat Oring on the pick up tube?

The best stuff for cleaning those old engines is "LA's Totally Awesome Cleaner" and it really is totally awesome. Soak parts in it for a few hours and u can spray thay old crud off. Or spray it in and scrub and it will come off quick.

I just fixed my 5.3 on monday morning just fell off tube oil pressure back to normal was not a bad job .

I changed mine, while replacing leaking pan gasket. at 272k, the inside looked really good for mileage. Cleaned every thing including pickup tube and screen. Put every thing back together, waited 24 hrs for gasket sealer as per recommendations. Filled with oil . unplugged coils and no oil pressure at all. BRIEFLY started to a noisy engine which confirmed no oil pressure. Any ideas other than pulling it apart to confirm o-ring wasn't damaged ? I am an autobody tech , with mechanical training. I followed GM service procedures and did not use screw to force the tube in ect. I am surprised and confused. Could the oil pump lose enough oil in those 24 hrs to hinder pump from priming?

Just picked up a really clean 2005 Z71 4x4. Oil pressure isn't terrible by any means (these 5.3L engines will run forever especially if taken care of), but it's a bit low at hot idle. Thanks for all the information and attention to detail in this video! I'll be doing this some time in the near future. Liked and subscribed to the channel!

I have an 06 with 412,000 miles. Repair shop wont do it because of the fear of the rear main seal blowing out with all that new pressure. I have been running lately @ 38 psi driving and 20 idleing. Use to be at or near 40 psi all the time. Looks like i will be doing this job myself. Thanks,

nice video..i have a question , you said @ 23:29 to disconnect coil pack before start the car..can i know the reason..? also is it important to disconnect it ..

Great video! I have to ask, you had the oil pump right in your mitts, why didn't you change it out?

Do you think doing the oring could quiet down noisey lifters?

I just bought a 2001 chevy tahoe 5.3 rwd and oh man i like the truck but it's been giving me a bunch of codes B2722, C0265 and P0332. The first two goes away by it self sometimes I erased the codes. The 3rd one is new. Is it worth replacing the body control module and EBCM?

You don't need to disconnect the coil pack harnesses if you don't want the vehicle to start. Just floor the gas pedal while cranking, and the ECM will shut off the injectors. No fuel, no start.

Hey, I appreciate your help, I couldn't have replaced this without you. I think I screwed something up though, my truck now is telling me to service the 4wd. Any ideas as to what I could have done to the differential when I let it down? Thank you.

Great video

Next time when you go to prime just hold the gas pedal at WOT it’ll kill the fuel if I’m not mistaken to help prime with out unplugging anything.

Curious. Do you have to rivet the new oil pan gasket or no? Do you add any sealant or just install dry? What’s is the torque specs for everything that was removed?

I get a ticking sound @ cold start,then goes away about 30 seconds later. my oil pressure is at 40psi any aideas,thanks.

Good job and love watching your videos. Are you going to the V Club Invitational at Ennis on the 26th of Feb?

Nice work

Our has 221 and doing same thing Will fix it this next summer so I parked it and start it every 3 weeks

Would this repair generally be the same on a 6.0 2500 Silverado 2WD?

Thanks 🙏

Hey did this solve ur issue it’s been a year since u did this. I believe I have same issue I replace few things n the end of the stick I replaced screen n sensor n o ring is broke

Mines on cold start is at 50 once it warms drops to 24 can it be the o ring aswell?

Very informative!

I got a 4WD and really want to do this but no lifts only ramps and Jack also my idle rpm is under 1k lol what would cause that ?

are these the same as a lq4 or any differences in procedure

Great work

I just did this job on 4x4 YukonXL. It’s a nightmare. You’re lucky it’s not a 4x4 like mine. I had to drop the diff to drop my pan. Replaced oil pump as well using a Melling high volume oil pump. Cleaning up the sludge was just as much a nightmare as the job . My pan was full of it as well as my timing cover, and valve covers. I used gasoline and brake cleaner to clean it all. After the job was done I I removed the sludge from the rest of my engine using a quart of diesel fuel in the oil. After I installed everything I ran diesel fuel in engine at idle fir 10 min then changed my oil.

did I miss something, did you not install the aftermarket second bolt holding the pickup tube on?

Did u add silicone to the corners of the pan?

Since the rack and pinion needs to be dropped from it's mounting position to do this repair, did you have to get the front alignment done? Or is it fine to just bolt up it back up?

Nice video, I just swapped my camshaft and a lifter and now at idle it fluctuates from 20 to 40, could it be the o ring? It got moved around during the install. Any help appreciated

Worked for me - back to 40lbs at 415000

Have you had any problems with head cracking losing antifreeze

Did you have to replace the 2 rivets on the oil Pan that held the gasket in place?

I just did my 2005 Z71 5.3L Tahoe with 330,000 miles on her, exact same problem but I also replaced my oil pump while I was there, four wheel drive is a much bigger pain and I did not want to do it twice just incase, now I get 45 psi on cold starts and over 55 with a light engine rev. I am hoping for at least another 100,000 from the old girl.

What's the difference of dry start from oil pan off vs oil change?

For all the sludge use gasoline and rags. Let the gas soak and it will wipe clean. And before i pulled the pan i used marvel mystery oil in the oil for a few hundread miles.

Just did this to my 05 Tahoe. I had around 25psi at idle and 40 max and lifter chatter almost constantly. Now it’s quiet as a mouse and idles at 50psi and up to 80psi under load.

thanks

i’d always like to replace the oil pump with a 10296 aswell

5⭐, amigo,,,My problem is with the oil pressure marking in the gauge when i start it, the gauge needdle don't move most of the time untill i press gas pedal it moves up but needdle keeps up n down, so i deside not move it, untill gett an honest diagnóstic...what can You do to guide me to know what to do with My old backupfríend in the outthere Chevy taho 2005, 4.8L, and Big thanks for the help

My 05 sierra 2WD has 190K miles on it... Im gonna do this job and will obviously change the oil. Should i get the thicker oil or stick to what it should be? I know some people say to add thicker oil at some point in the trucks life but dont know if thats a good thing.

Great video. Lots of gratification seeing that pressure go up. I have an 03 5.3 an thought i had a bad rear seal but I’m guessing the bigger leak is the oil pan. Getting psyched for the job- you have some good tips. One question I got, a while back I snapped one of the long bolts trying to tighten up the pan. 🤦‍♂️ I’m not planning on extracting if it’s buried. hoping a new gasket will suffice 😬.
