I just can't win.... I see all these cool diesels at the tracks, running great time and driving away.... I can't seem to get there. I have no diesel mechanics in my area so, I'm having to go at this myself.

Took my truck to the track yesterday and after a couple great 14.0's in the 1/4's the trouble set in.

Third run down the track at about the 1/8 the power changed from kickin' butt to spitting a sputtering and white smoke started to bello out.

I was running on the Smarty beta 4.3 #7 and had the TST on #2 and TT03 everything else was shut off. It saw some very high EGT's but, from what everyone has said... in a 1/4 race everyone does.

At the end the track crew is yelling at me to pull over and shut down ! They thought I was on fire there was so much smoke.

Popped the hood and it looked like a oil bomb went off in there. The entire engine compartment was covered in oil.

I have ARP studs so I don't believe my HG gave out. In looking at the motor I don't see any signs of HG failure either.... no water that I can tell in the oil.

What I do have is a ton of oil in the exhaust. At the clamp that connects the down pipe to my muffler, oil was pouring out... at least a quart or more.

I was figuring I blew out the turbo but, what's weird is the oil all over the motor seems to be more on the drivers side. The turbo barely had any oil on it.
My dip stick didn't blow out and neither did the vent tube.

Can you guys help me with some in site on what all could be wrong here ? Don't be shy... I can take. I played and now I pay... some more

The truck runs but, very rough. If I start it, the oil will start to drain from the exhaust, nothing but white smoke comes out but, I think that's because of so much oil in the exhaust.

Ok, I got the turbo out and also took the exhaust manifold off.

4,5 & 6 cylinders were wet with oil in the ports. More in 4 & 5... 6 was a little dry. The turbo didn't have any shrapnel but, the exhaust side wheel has a grind to it when turned. It does spin freely but slowly and sounds/feels like it has sand in it.

If the seal on the exhaust side of the turbo went out, would that cause oil to back up into the exhaust ports ? I'm grasping here hoping I don't have piston problems.

I don't have water in the oil so, does that rule out a head gasket ?

This is my plan.... replace the injectors, turbo and exhaust manifold. I have a ATS manifold that's been waiting on my turbo.

When that's done.... dare I crank it ? Or, since there oil in the exhaust ports....do I need to break the motor down to check valves and pistons ?

did the turbo seal go and send oil out the front and through the intake maybe???
sounds like turbo to me but the oil in the ports is kinda throwing me

so I say check the intercooler see if you got oil in there?

tritont

in looking at the port out of the turbo to the cooler and the hose leading to the cooler, there's no oil that went that way. All the oil was on the exhaust side.

What gets me too is, I can't figure out where the oil came from that was all over the engine compartment.

Well, let's go through the flow here a sec. Air comes in the air intake, into the turbo, through the turbo and into the intercooler, then to the intake manifold and into and through it's necessary engine components and out to the exhaust manifold then through the outlet and out the exhaust. Either your turbo is crapped out, or you have internal (engine) failure...i think that if you drop the turbo and feel inside your exhaust manifold and there's oil in there, you have completely troubleshot and narrowed it down to engine internals...I personally think that you may have cracked a head, head studs or not. Just because the head GASKET didn't blow off and the studs did their job correctly, doesn't count out failure internally that it contained. I'm sorry bud, but if you have oil all the way from your exhaust manifold out the tail pipe and NONE going into your intercooler and intake manifold...you're problems are in the engine.

As far as oil being on the DRIVER side...that's weird...I can't really explain how it would get there. You have checked EVERYTHING good for leaking/damage on the driverside EVERYWHERE? I see that you have an FS2500 and I'm assuming it's mounted next to the intake manifold right? could that be your culprit?

tritont

well, I do hope your aren't as right as you are about the FS2500 with the cracked block. That was my thought also that oil leaked BAD from the by-pass and the fan blew it all over the engine. Haven't got to that yet

So what are you talking about internally ?.... pings ring gone, melted piston, valve blown out ? I find it hard to believe the block is cracked... I guess it could happen but, that's one solid hunk of iron in there.

This does suck but, I suppose gives me the opportunity to go ahead and build the motor from the inside out.

Sounds to me like the turbo came apart and probably blew the oil supply line, that's why the oils all over the place. What kinda boost were ya running?

$oC@l CTD

Oops...worded that wrong...I didn't mean to insinuate that you had a cracked BLOCK...but if your engine is running badly then I would think that you have a jacked up piston or valve, maybe blown injector. Have you checked your oil levels and smelled the oil for fuel, etc?

tritont

the oil does smell a little funny. Not necessarily like fuel more like a funky pungent smell.

By the way it runs and the bellowing white smoke... I'm hoping it is injectors. Have a set in the works and that would be a whole lot better than the alternative

buckshot... thanks but, I don't think that's what happen. I just took the turbo out and the oil on the engine definitely didn't come from there.

My oil smelled like that after I blew the head gasket on my 97 antifreeze and oil together stink.

tbarbee1

Hey tritont does your exhaust have that same nasty smell ??

tritont

I didn't check that. What would that say ?

Totallyrad

Head gasket sure sounds probable. It would explain oil in all the places you describe. How long have you had the studs in and how many times have you re-torqued them since installation?

53 willys

if a injector(s) where blown then why would there be oil in the exhaust????
the turbos I have seen blow oil seals have no oil on the head exhaust ports...just oil from the turbo exhaust back down the tail pipe....




is this stock turbo???
what psi where you pushing???

tritont

Yeah it does but, I just don't see that that's where all the oil came from.
The studs haven't been in long... a month. From what Garmon told me though, they way they he torque's them... in 5lbs increments all the way to 150lbs... a retorquing wouldn't need to be done for a while.

plug the turbo return line and fire it up with out the turbo on.....if it still smokes like crazy you have got to have some head-gasket/head issue of some sorts......
