Here is my dilema. Had been having problems w/ my turbos and after many moons I finally got a set of 99 spec and took care of that. Here's the problem, my car is still smoking pretty bad. Car runs great now, engine sounds great, boost is good, vac is between 10 and 12 at idle, and it idles pretty constant at 800. I don't think it's the oil left from the bad turbos b/c it smokes as soon as you start it up. Smokes lightly at startup and idle, when you're driving the faster you go the more it smokes. I can see a tiny bit of oil in the tip of my exhaust. I had my compression tested not too long ago and had 7.1/7.2 all around minus one face that had 6.7. I don't drive my car hard either. What should I be looking for here, bad motor, omp, pcv? Every time I fix one problem I find another, someone plz help me.

My mods are mp, dp, air pump removal, pettit remapped ecu, pettit open air intake, street ported pettit engine w/ about 40k, M2 medium SMIC

doesnt sound like a turbo problem,,ive had lots of experience with busted turbos,,they tend to smoke after you let off throttle after boost, and not really on tick over (and if the seals where that bad that it smoked on tickover you would know about it because you wouldnt be able to see for smoke),,, so id be going somewhere else how olds your engine, was it a full rebuild,, i hope its not the rotor oil seal rings..,,,are you 100% sure the smoke is oil,,,if like you say you got oil in the tail pipe thats not good. (i dont think its the oil metering pump,,,,because i think even if the metering pump was set to pump full oil,,,it wouldnt be enough to get oil in the tail pipe),,, lets see what any of the other guys have to add here

If there's anything I'm sure of, it's that the smoke is definately from oil and not coolant. I've been working on cars long enough to be sure of that. Thats about the only thing I'm 100% sure of right now. As for how old the engine is, I don't know. That's about the only information I don't have from when I bought the car.

Perhaps the check valves in one or both of your OMP injectors is bad....

I'm not familiar w/ the omp so I don't know what that would cause or even where those are located.

rynberg

The OMP injects oil into each rotor chamber using an injector, which is mounted on the passenger side of each rotor housing, near the top. The injectors are "pressurized" by vacuum lines from the intake tract. If the check valves in the injectors go bad, the oil can be blown back down these vacuum lines into the intake tract. The higher the boost, the more oil blown back into the intake tract -- making for a smoke screen AND depriving your poor apex seals of oil.

Just another potential source of trouble to keep in mind.

I meant, by not familiar, that I haven't worked w/ it. I did understand how it works, however not that specifically so thanx. On that note I've changed all the check valves w/ viton ones from dale clark. So, I would assume that can be ruled out. One thing down, lots to go, lol.

Is it a lot of smoke or a little? I wouldnt worry about it unless its alot.

rynberg is on about the check valves that are built into the oil injectors (not the little white and green plastic ones),,, when you unbolt one of the oil injectors it has a check valve built into the top of it (check manual for more info) ,,, i still dont think its oil meterring system ,,but i think theres a guide in manual for checking the oil injector check valves.

Perhaps the oil return line from the newly installed turbos is kinked / blocked?

pearlyellow

Return lines are clear checked those already.

when was the last time you changed your spark plugs? I thought I had a bad set of turbos and it turned out my plugs were really fouled. Had intermittent smoking. Just another possible candidate.G

pearlyellow

Changed the plugs I put the turbos on.

what do you know about the turbo's,,, are u 100% sure they are good(was they new),,,try pulling the pipes off the turbos,,,there should be no oil in the compressor housings.

pearlyellow

The turbos are brand new 99 spec. I am starting to think the oil in the exhaust was just what was left from the bad turbos. Drove it home from the garage today which is about 30 miles, exhaust dried up and the smoke died down but still smokin. I have no doubt the plugs are fouled so I'm gonna change them and pcv next weekend. Still would like some help to nail the problem b/c at this point I'm lost.
