6.4 and 6.7 powerstrokes have positive crank case pressure there will always be steam coming out of the oil fill and vent

Ford tech here. A bit of smoke out of the oil cap is normal, your friends 6.7 seemed more smokey than normal though. Just as long as there is not positive or negative pressure when you put your hand on it. Will be a bit hard to tell since he has a CCV reroute. If you’re concerned about the compression, have the dealership do a relative compression test on IDS. The 6R140 trans in the 6.7 is stout as fuck, too. It’ll take a beating. He must have a 11-14, because he has the twin scroll/dual boost turbo. They’re not bad turbos, but definitely not like the 15+ turbo that went back to a 6.0/Duramax style. You can actually retrofit the 2015+ 6.7 turbos using all factory parts.

I paid $32K for a 2012 F350 Lariat Super Duty, 6.7 Powerstroke, 4 door, 8 ft box, 4x4, not a dually. I added a block heater and air bags. Was at 169K miles. Now 176K miles. I like it. Twice the horsepower over my 1995 F350 7.3 Powerstroke, 4x4 dually.

Who has a mechanic as a friend and doesn't take them with when they go and buy a new vehicle?!?

Power strokes all have a little blow by!!! Run that baby like you stole it! $27k is damn good for a king Ranch! Very clean truck

Hope it has the heated tailgate! Wouldn’t want him to get frostbite pushing it home this winter.

Glad you were able help fix it. I’m sure he really appreciated it. Not everyone has shop like yours.

I've come to the conclusion that with trucks made after 2000, it's really a matter of choosing which set of issues you want to deal with. They all have some major upsides. They all have their downsides. But which set of downsides vs the upsides do you want to deal with?

The “smoke” out of the oil cap is somewhat normal on these 6.7. Mine was doing it brand new, my friend bought his new as well and I asked him to check his at 5k miles and it was doing the same thing. What you don’t want is pressure in the oil cap. It it pops then you have an issue

First time I rode in a 6.7, I was blown away by the acceleration. 7 people loaded up in the truck on a pool trip. The owner let it RIP, and I couldn't believe the stark difference to my dad's dog-slow 6.0.

Very common a freshly rebuilt engine to have blow by until the piston rings seat. See it all the time on rebuilds especially diesels

If the blow by isn’t lifting up the oil cap I wouldn’t worry about it.

I have a 2016 6.7 and it huffs out the oil fill too but with no pressure behind it. Been told it’s normal. Keep us updated

I bought a 2007 LBZ last spring, boy did i get screwed, someone was in it before me that had no clue what they were doing. So here i am after doing injectors, cp3, turbo rebuild, headgaskets, water pump, and a harmonic balancer later. Sucks that i had to blow through over 10k. No one should ever have to do that. Really made me want to get out of a diesel.

Work it hard for break in! Nothing worse than babying the truck right after a rebuild. I was told by my Dad that a customer once brought in a 11 liter cummins less than 100 hours after a rebuild with loads of blow by. They took it for a road test and hooked it on to a heavy trailer and gave it all she had and came back. When they checked for blow by after it was gone.

I've had multiple 6.7 trucks in at my work as we work on a large fleet of f450 trucks. There's been a few trucks with the crank case filter clogging and causing excessive pressure but that's a simple fix. Just had to replace the filter. There's been a few deleted trucks in with the ccv reroute and I'm not a fan of the reroute kits. They've all smoked like that and it just doesn't seem like a good kit to me. On my 2013 f250 6.7 I left the factory ccv housing on.

Josh, everyone i know with a diesel truck carries. i was thinking he is missing 1 piece on that truck! then you showed it! nice job with the fix on it. check the ccv areas for that blow bye. Keep Rollin!

Soapy water in a spray bottle would help you out when checking for boost leaks

6.7’s are absolutely bulletproof. Chevy guys hate on them but the hate is beyond misplaced.

I have a 96 7.3 600,000 plus an 01 with 400,000 plus and now a 14 6.7 with 230,000

I build cummins, from 300hp-1500hp when I set my ring gap on higher Hp trucks I set them lose and I always get fumes/vapor. It’s nothing to worry about. The only time you need to worry is when you are getting actual pressure out.

I’ve enjoyed watching and learning about diesels from your channel. Nice to see you working on and showcasing PSD on your channel 😁 Literally down the road from you and if you’re ever up for changing glow plugs in a 7.3L PSD, hit me up 👍🏼🤞 Keep up the great work, Josh.

I had a ccv reroute and had blow by. I then put the stock ccv filter on an the blow by went away. It’s because when the ccv hose is routed into into the turbo it pulls a vacuum on the crank case so when people do a reroute there isn’t negative pressure and therefore creates blow by.

Certified ford diesel tech here, The vapors are normal especially when it’s cold out it’s more noticeable my 6.7s has been that way for years also after a fresh oil change but Make sure there’s no kinks/ restrictions in the ccv reroute.

Heard on the video for sure. That 6.7 is miles a better motor than the 6.4 and 6 liter are. But, I still love my 6.6. No need to change it.

Ccv reroute isn’t leaching the pressure out of the case enough. Put back to stock or put a new/better reroute kit on

I have a 2014 with the retrofit turbo and HPFP. 566 to the tires!!! Love the KR interior!

My old 2015 6.7 would push vapors out of the oil fill, but no pressure. From all the research I did, it was a normal thing. I can't remember if it was to that extent or not, but I wouldn't be to concerned. Just keep an eye on it

Minute 9:00, spray bottle with water and some dawn dish soap in it. Not sure if it would affect anything but that’s what we use on dive boats to find leaks in our compressors, bailout tanks, etc. just look for any large bubbles. Saves time rather than trying to feel where the air is coming from. I’m not a mechanic so not sure if that would be all that helpful but just thought I’d share. Cool truck

Gotta love when people slap on "super duper race performance" parts but leave massive boost leaks everywhere

That blow by is not an issue. Unscrew the cap and set it on the hole if it doesn’t blow the cap off it’s fine. Your going to have some crank case gasses on a diesel.

We are ALL overpaying for new or used, me included! My 2012 KR F350 DRW Had 28,800 miles on it and I gave $50k for it 5/22. Same colors. Love it, so worth it to me, it did have everything and some extras. Private party, owned by an airline pilot, garaged, looks new, everything aok so far, now with 30k miles. If I keep it 20 years the price really won't matter much. New one is 95k, so.... yeah it's all relative. 50k was below black wholesale. Pilot went and bought a f450 Platinum for $105k, so were all paying bigger bucks than just a few years back.

Josh you are the man to figure it out. Love to see you helping other people. That's what we all should do. Man I am waiting on WIFEMAX!!! Like a kid in a candy shop. 👍👍

Josh, your friend should have taken you along to look at truck before he brought it 🤔

I rebuild diesel engines. Give it some time for rings to seat before condemming it.

I've seen on a similar style air intake system where you reroute the ccv system through an aftermarket ccv where a incorrect bolt had been put in and wasn't allowing crank case pressure through and was causing excessive pressure through the cap.now that style of ccv was a type of air oil separated and was too far down causing it too stay closed.now you might have a different style of aftermarket ccv however I'd make sure it venting correctly and allowing enough pressure through and not restricting.aftermarket parts can be hit or miss, even if it is venting it may not be enough.

I have the same exact truck. Bought it from a friend who put a brand new Ford long block in it. Had 150k on the chassis when I bought it and like 200 miles on the engine. I’ve had it 2.5 years only maybe 15k miles on it but it’s had zero issues. It’s deleted but I don’t hot rod it at all.

Make sure the hose on the crankcase reroute isn't kinked. That engine should not smoke like that if the reroute is installed correctly and the hose is not kinked.

You are good friend ,help the other came from God, God bless you, today just fixing my duramax lb7 put a new fuell filter keep on shep thank you Bady

My wife commented that the boost leak sounded like a sad ballon ( letting the air out by hand to make it squeal) 😆👍. No offense to Ford , or Ford owners , but their latest offerings aren’t “ Better Ideas” in my opinion . Give me a mid 1970’s Ford F-250 4x4 any day over a new one . And I’m a G.M. guy ……. Love my Non Emission 2002 LB-7 2500 GMC Sierra …👍 Glad you found the leak on your Buddy’s truck , as ANY leakage causes issues , especially with all the sensors & interplay between ECM’s & components.

Ccv hose is kinked. Cut the hose short and let it vent to the atmosphere. Route it over the brake booster and down beside the shock. Avoid a catch can in really cold temps. Condensation freezes and will cause increased crank case pressure and puke oil through the turbo and out the exhaust. Make you think the motor blew. I have a 15 King Ranch I’ve spent some money on. Learning things the hard way. I’ve learned quite a bit over the 2.5 yrs I’ve owned mine. Bought it with 75k miles, it now has 113k miles. Catastrophic fuel system failure at 85k led to a bunch of new parts.

Make sure the reroute hose isn’t pinched if u have blow bye with a reroute check to see if u have anything coming out the hose under the drives side

Always great to have a buddy extra set of eyes and ears when troubleshooting

My 2018 smoke out the oil fill as well. No pressure behind it. Was told if there are pressure to replace the crank case filter.

Blow by could be from the ccv re route depending on how it’s re routed. Needs to be routed into atmosphere towards the rear of truck.

On a fresh inframe on a semi truck you get a lot of blow by until the motor is broke in maybe the 6.7 is the same way

I just bought a 15 PS. Also light smoke out of oil cap. I was told it’s definitely normal with these trucks. I came from a fully stock 2018 cummins Night and freakin day from the cummins. But my PS is completely taken care of and tuned Maybe it’s cause the cummins wasn’t deleted. But I don’t think I’d go back to a cummins after driving a 6.7 PS. Truck is insanely fast

Josh if the oil has coolant in it sometimes that can thin the oil causing the blow by or a cheap break in oil take a look at the oil from the pan if there are shavings also if the piston rings were not clocked right blow by can happen or whatever cylinder it was that had the injector tip issue wasn’t sleeved just reboared and a stock replacement piston and rings were put in on drag racing engines after a number of times where the rings are not touching the cylinder wall a bigger piston and rings get put in

Purchased my 2011 king ranch psd with 219k it has oil vapor similar maybe a lil less. Been to the floor more times then I can count and it doesn't care at all. Truck has 242k now still loves the abuse

The smoke from the oil is normal but when it blows it off thats when you gotta start getting ready for it

I always put my oil cap on upside down while it's running if it doesn't immediately blow it off I'm not too worried There's always a little bit of blow by on every vehicle. Plus it looks like it's pretty cold out so it looks worse than what it is.

fresh built diesels will inevitably have blow by until the rings seat themselves and get a working groove in and seal completly. not to mention that amount of blowby is normal for ANY diesel with a CCV that vents to atmosphere. i'm assuming its got a CCV that vents to atmosphere. if it had a CCV. that was piped into the turbo like factory. then it'd definatly be cause for concern

My 6.4 was that way. They were notorious for the gases coming out but never did it blow the oil cap off. Always a worry with them.

Check the ccv. If it’s re-routed, put it back to stock with a new filter and see if it still pushes blow by out the oil fill and dipstick.

I just put a new motor in my lml and it does not have any smoke or steam coming out of the oil fill or dip stick tube like his does. It also didn’t have any smoke or anything close to that before the original motor blew. That would definitely worry me

That’s a good friend you have. I drive tractor trailer for a living. This is all normal.

I’ve seen the turbo kit he has in action before the non vgt turbo sounds great slightly laggy but hauls the mail compared to factory

Love the Trigicon Night sights on the 9mm 😄 not a Sig for sure passes for G19 😇 .a surprise in every vid you post !!!

my biggest mistakes buying used trucks was once buying a used ford

I learned how to drive a towed vehicle by my dad before I had a license. Michigan born and raised.

We had this same noise on a tractor trailer truck it was a loose clamp on a rubber hose coming off the turbo

Great job the new stanadyne s&s pump is a game changer for these trucks

The engine is fine, the PCV system creates the smoke. See it on trucks all the time low miles

Fresh motor new ringd. Little blow by. Is normal. Give it a few thousand miles. Then rings should seat. If it blows cap off. You have issues.

But I would change the crank case filter frist be for thanking anything bad

Mine was the exhaust manifold bolts. The gasket was like a blade of grass between your fingers and would make that sound.

Great channel brother!

6.7s have positive crankcase ventilation the have a haze from factory

Pulls out the handgun😂🦅

Soapy water in spray bottle is good for finding boost leaks. My 2011 6.7 with 160k miles doesn't have any blue by yet. There are metal shavings in my fuel filter though, so my high pressure pump is probably gonna fail.

Soapy water is an easy way to check for and locate boost leaks, or any kind of gas naan.

That does t seem out of the ordinary for these 6.7 trucks. My old work truck was a 2012 and it had that much blow by off the lot. Sold the truck with 270k and no issues. I also have a 2012 6.7 and they have crank case pressure that’s a little more then most diesels. I wouldn’t be concerned.

The blow by on that truck is nothing to be concerned about. Seeing vapor is pretty common, but as long as there is no pressure, then the truck is healthy. As far as the issue of the glow plug breaking, it’s actually the exhaust valves on the 2011 trucks with a build date prior to 04/11 on the the door. There was a bad batch of metal and over time the valves crack and break. Pieces fall into the combustion chamber and mash up the piston and break the glow plug tip as a result. That’s where this truck most likely had it’s failure come from. It also has a non-VGT kit on it as well, looks like a Smeding piping kit and most likely a Smeding turbo. That should be a pretty reliable setup over the GT32 found on the 11-14 trucks from the factory.

So the engine was just rebuilt and you have no problems letting it sit and idle but you don't want to push it hard? Good luck with that break in strategy.

You guys are right. They are all awesome. The most fun I have ever had driving & I’ve owned some fun vehicles to drive. I’d certainly sooner drive a diesel truck any day over a 4 banger or EV😂

Best ford engine was the 7.3 still got one on the road with over 500 thousand with the original engine. LBZ to me was the best engine Chevy put out

Hey Josh good test and a good job.

i have that excact same truck mine is 2012 107k mint condition! i love mine get comments aLL THE TIME

When doing a break in that’s the time to get on it so the ring's seat. You shouldn't take it easy and let it idle for extended periods of time like in the video.

I'm not a Powerstroke guy but one of my 6.7 Cummins has a small amount of vapor with no pressure, no issues with it so far. I think some motors just do it.

That’s common on a 6.7. Just run it and it’ll be just fine

check the vacuum pump and lines..... I know on my cummins if theres a vacuum leak it causes what looks like bad blow by

The problem with a rebuild is and will always be the human factor. Who can you trust. Without knowing the shop and mechanic personally I would never risk it.

Can you post up a link to the boost pressure gauge setup you used? I’d like to check my truck for leaks.

Glow plugs weren’t the issues with the early trucks. It dropped a valve and took the glow plug tip off.

Looks and sounds great!

Hello Josh. Your friend got a new Ford F250 Powerstroke 6.7 is sounding good. You can solve the problem.

Should open up a shop, truck master diesel!! 27k too much for the truck. Just my thoughts!! Love the content!!

That sounds like my exhaust manifold/ up pipe leak, which I need to fix, since putting on ppe up pipes.

I had to brand jump. I wanted another Ford but they haven't been able to build a decent one since the 7.3. Did some research and was able to pick up an LBZ with under 100,000 miles in the Southwest no rust for 29 plus taxes and fees. It took me two and a half months and had to travel close to 300 miles so I hope I made a good purchase

As a 6.7 powerstroke owner I'm not at all worried about that blow by.

Replace the crank case ventilation filter, they get clogged up

That was a good video, but I sure would like to see you use the Cummings more

Check the ccv reroute hose make sure it’s not pinched.

2011 had issues with ceramic bearings in the turbo, bad ideal, and dropping valves in heads

Check the crank case filter it might be clogged

I did the ccv re route on my 17, no blowby under normal driving but it does have about what u have with my 21k camper behind It

I think the blow by is from the ccv is plugged.

27 is about right for that truck. It appears pretty clean with a fresh reman . Mine was nearly same price and not a KR but lariat about 180k miles one owner and stock

i beleive on the right side it has a filter in a black box for crank case pressure they clog up too if their not deleated
