Oil In The Exhaust? What Causes It and How To Troubleshoot It.

[@camshaftP16]

Good use of the smoke machine, we see lots of slobber issues when drivers idle for long periods in the cold. Use to see lots of broken rocker arms too, on the acerts when it gets cold out (-30c) or colder drivers would say they were getting great boost, 60 psi or more then POP! there goes an intake rocker. good video thanks.

Maaan you saved me some stress.... Oil exhaust blow back and blowing smoke like a train. New turbo and replacing oil lines... Hopefully will fix the issue. Very helpful video 👍🏻

[@Gabriel-x3r4r]

thanks man I was freaking out but I think it was oil somehow getting into exhaust! Great video

[@manz1397]

I have a tractor (JD 4020), that has a oily residue coming from the exhaust manifold where it goes into the stack. I have concluded that it is more than likely caused by the engine (apparently designed to not use valve seals at all). If you don't heat the engine to a good temperature, or if it is not worked hard enough it will not fully burn the diesel, and it collects in the exhaust.

[@petermolnar8667]

That would be called wet stacking 👍

[@kamalnadan6114]

I just experienced excessive white smoke and oil leakage on my Cummins N14 exhaust pipe, this video helped a lot, thank you. Unfortunately in Fiji they don't keep N14 parts...

[@JackJensen-il6ji]

This is l exactly what I have on a C4.4. Engine would also runaway when it ramps up. Did cylinder cutout none of them are dead . After running away when you pull piping on the tubing side it’s dry. Ran the engine for 1 minute and it was a puddle of oil. Pulled CCV filter it does look dirty but I’ve seen worse . Pulled air filter it’s not too bad . Will replace the turbo and retest.

[@afc-sw5qn]

Love the channel being a cat tech myself its nice to see different ways of doing things to make the job easier. The smoke machine is a great idea and will be ordering one soon. Keep up the good work.

[@enchantedwenis4994]

For you Cummins ISB guys. A restricted air filter or crank case filter can cause the turbo impeler seals to leak. For you Hino guys, a leaky turbo is normal. Hope I saved someone a couple grand!

[@lukasgrincevicius6245]

That oil return line can be really problematic, since the return tube/sealing surface really doesn't want to stay flush with the turbo side and it's so tempting to just tighten up the bolts to make it seal. Wondering what could be done better than just using rtv sealant on oil return to seal the gap and not over tightening the bolts ?

[@mikejankoviak8542]

So when this happens would there be oil in the manifold when you take the turbo off?

I just found a turbo on a c15 that the exhaust side was dry of oil.. but it fails the smoke test. Engine was consuming oil. Going to replace this turbo and hope the blow by shows less vapor and froth.

[@Darth-Nihilus1]

We had a oil seal fail on a 6v53t and it ranaway on us, luckily with 2 strokes is that is doesn't need the turbo because it has a roots blower. Sit runs since we removed the problem

[@timbendomscelestine1312]

very nice Sir it is truly enlightening

[@FleetTech97]

So what direction would you go in this scenario? White smoke that really burns the eyes. Lots of blow by coming out of oil fill cap. Iv tried turning individual injectors off to see if smoke stops but it stays the same with all cylinders. I did find a little bit of oil in the intake turning on the turbo and the rest of the intake piping. No misfires

[@ramilacilo435]

Push rod failure looked like a 5EK. Good use of smoke machine, I'm going to have to use that one. Thanks!

Adam Cole yea I should think before I type sometimes. I was looking at the style of lock nut on the rockers when I was thinking that. 5EK and push rod don't go together. LoL

Would the presence of oil in the exhaust side of turbo be enough to tell you seal is bad ?

Hi I have a caterpillar 3406-DL and the serial number is 4CK03404 and it doesn’t have the sticker where it has the information for the motor and I want to know what the fuel timer for this engine is you can help me in any way please write me back

[@johngoldsmith6629]

Have no ideal what a DL means. The 4CK03404 engine is a 3406C. You have a PEEC engine, 350 HP, FLT. The timing sensor you need a special tool and a electronic tool to read timing in ECM. You can adjust pin timing. Your fuel system camshaft static is ten degrees. Timing is controlled by the personality module.

I always thought turbos use centrifugal force to (seal) them throwing the oil outwards towards the drain Turbos will never seal

you missed one cause that iv seen before, crank case filter plugged up, will cause hight crank case pressure and push oil through your turbo seals leading you to believe you have bad turbos

@@Uc9uE3pKsS6uQ , it's called Crankcase breather filter or Oil Separator Filter. Drivers side by the oil pan. If your truck has a Breather Filter and it gets clogged, it will cause high oil pressure.

[@samm9174]

What if you do have alot of blowby and steam coming from the breather? Only when it's at temperature.

[@AdeptApe]

Well if you have steam, that is probably only going to come out when the coolant/water in the crankcase is close to the boiling point of water. It isn't going to steam very much at 70 degrees. Hope that makes sense.

[@samm9174]

@@AdeptApe ok yeah I'm pretty sure it is the coolant that is being eaten up. It will slowly drip dirty water out of the breather when the motor cools. My guess/hope is it's a head gasket. I can hear bubbling coming from the heater core and it eats coolant. It's a 94 12 valve. Probably need to pull the head to figure out of its the gasket or something really awful. Are those motors prone to cracked heads? The blowby isn't horrible and seems normal when it's cold.

Hey y'all, I have diesel fuel coming out the exhaust ports. I have no issues driving. It actually starts up no problem (cold or hot), drives really well, has great power and very smooth operation. The only issue is that the 2 of the exhaust ports are wet with fuel when I shut off the truck. I thought it was oil, but my oil level doesn't dip. I replaced the thermostat and serviced the cooling system to make sure the operating temps were up to spec. Any suggestions? Bad injector? Cylinder problems? Wet-stacking?

[@JaGGeR-]

I would suggest checking the injectors first. Could be as simple as a missing or damaged o-ring.

[@generalcaeser9176]

I need help. 2006 Jeep Liberty CRD Diesel: I was pulling 4k pounds for about 500 miles and the last 80 miles was a solid gradual up hill. I noticed it wasn't going into over drive about 20 miles before the big problem started. We heard a pop. Not a super loud pop but a pop any way. Noticed there was zero oil but was idling fine, just no power at all. It would move a foot and stop so I quickly shut her down. Sent a friend down 6 hours from home to pick it up. He poured a gallon of oil in it and it all ran out. He said a lot of oil was coming out of the exhaust. It doesn't overheat or smell like burnt antifreeze. Also there was no check engine light on but the oil light did come on a little and I added some oil but the oil light went off and never came back on. Did I blow my motor or am I lucky enough that this could be just the turbo or something even cheaper? I can't afford this right now. =(

Gamet logging did you ever find out why you're cylinders had excessive oil in them

[@TANKERMONKEY]

Can this also go the other way and cause blow by

[@danielstarnes7354]

Do you mean exhaust leaking through the turbo oil seal into the oil system? Doubt it, oil pressure is higher than exhaust pressure. Blowby is caused by cylinder compression leaking around the (worn) piston rings and into the crankcase. In some cases of blown head gaskets or cracked heads you will see exhaust getting into coolant channels and pushing coolant out of the engine, but this seems unlikely with oil.
