I heard a pop earlier today when i was driving and the truck started spewing lots of white smoke...Like so bad that cars were stopping because i was filling the whole street with white smoke from the exhaust. There's a ton of oil at the top of the engine, slightly behind the turbo that is visible from passenger side but not the driver side. There is a small metal line going into the top of the turbo (I think this is the feed line?) and there are no visible leaks here. I think I can see from the driver side where the fat (about the size of a garden hose) line is and no leaks there, but i cannot see behind the turbo. Where is the oil coming from?
What year is your truck do you have the icp sensor under the turbo 2003 to 2004.5 i believe or 05 and later its on your valve cover .rubber o ring could have let go
Hard to say if it is the EGR, the turbo, coolant, or injectors. That said, anytime I see a post on excessive white smoke I cringe because if it is injectors (and excess fuel), that can ruin an engine.
1) There was a bunch of oil dripping down the block on the passenger side (left a small puddle on the ground)
2) The exhaust tips were wet with oil
3) EGR Cooler and EGR Valve have been deleted. I can see part of the hose from the delete kit and it is dry, where I can see it.
4) When it first happened there was some white smoke. I came home and let truck sit for a few hours. Then drove it again and it seemed to drive normal. Took about 4 min of driving before smoke came out like crazy. Could this be excessive crank pressure? I'm tempted to start it now and see if it smokes again just idling in the yard now that its sat for an hour or so.
I hope this helps narrow down a bit more. Anything I can do to further investigate? Thanks in advance.
So you are pretty convinced it is oil burning that is causing the exhaust smoke? Not losing any coolant? Also, the exhaust doesn't smell like diesel fuel?
Assuming it is oil, I guess I would first be looking for oil in three places.
1. How much oil is in the air inlet to the turbo (ie coming out of the ccv vent)
2. How much oil is in the turbo air discharge boot (possibly from the oil coming in with the ccv vent, but also could be a leaking turbo seal)
3. How much oil is in the turbo exhaust to the downpipe (would have to disconnect the downpipe or pull the turbo to examine).
Here's a couple of pics. The downpipe is a 4 inch and doesn't look like it would have enough room to move back off the turbo and see inside. I did feel under the downpipe clamp and it was wet with oil.
If you're that far into it, how much farther away are you, from simply removing the turbo itself for inspection? From your description, I have a feeling pulling the turbo will answer a lot of your questions.

I could definitely do that I’m just not sure what I’d be looking for once I had it out. Would I need to disassemble the turbo itself once it’s out? If it is the turbo can it be rebuilt or would I need to buy a new one?
You would be checking for radial and axial shaft endplay. By your description of oil leaking from the passenger rear side, I suspect it's leaking the downpipe the to turbo connection, through the Marmon clamp connection. This is why I suggest removing the turbo itself for inspection. From how far apart you have it so far, it's only the oil supply line and three 10mm bolts away from removal. If it is in fact shaft seal failure, you will either need to replace the center housing assembly (if it's even still available) or replace the whole turbo itself.
ADDED: Having the turbo removed will also enable you access to inspect the inside of the up-pipe connection into the turbo as well as the inside of the downpipe. If you see it dry on the inside of your up-pipe but wet on the inside of the downpipe, then you know the turbo is your source.
m-chan68 nice to see you in for a visit.
I agree. he is in that far and should go ahead and pull the turbo.
Also I think pulling the EGR valve would give some answers
That way he can see if it is dry or not in there.
Turbo is out. Up Pipe is dry and down is wet with oil, as well as the driver side of the intake manifold had some oil as seen in the pictures. I spun the turbo wheel by hand and it felt like there was a dry rubbing feeling, not quite grinding but it didnt feel right. There wasn't really much play in the shaft . Based on what you all have told me it sounds like the turbo. Is it worth having someone rebuild it or is it time for a new one? Any other things it might be before i drop money towards a turbo? you can see oil on intake Up pipe side on turbo you can see oil inside the turbo
Thinking about it, there shouldn't have been any oil on that driver side intake if the oil was just leaking out of the turbo. Maybe that dripped out of the PCV where it connects to the air intake tube? Could lots of oil come through the pcv and pass through the turbo? If yes, which pipe/s from turbo would have had oil pass through them? What could cause that to happen?
