    Question Turbo Blown??

    First I want to start by saying I have not done any sort of breakdown or "real" testing.

    I currently have the Technique Tuning Stage 2 Turbo Setup on my '03 330i.

    I have forged CP 8.8:1 Pistions, a .82 exhaust housing, and ZHP cams.

    Everything else is Nick's Stage 2.

    So my starter was bad and I ran in Chipotle and left the car running and I come out to the car still running but a cloud of smoke(coolant). What happened was I worked on the car earlier and forgot to plug the fan back in so a hose busted. A guy outside said it had been smoking for about 5 min.

    I got the car towed home fixed the hose and started it up. It runs fine but now after the car is warm and say I pull up to a traffic light about 30 seconds of idle and It starts pouring out smoke(oil).

    It only smokes at Idle and I had a friend follow me to make sure it wasn't just because I was going fast and I couldn't see it.

    I automatically assumed I blew the head gasket but I have to Oil in the coolant or coolant in the oil. Also the car runs great and its been about 2 weeks I figure (from previous experience)that if oil was getting in the combustion chamber I would have killed my spark plugs by now but I haven't......

    So multiple people tell me its a good chance the engine is fine and I actually just blew the turbo.

    if you blew the turbo, it probably has nothing to do with the chipotle incident. Do you spend millions of dollars on underwear? how do you deal with it?

    I was almost on the floor laughing at this....my better half didn't think it was so funny.


    Greg,

    What happens if you rev the engine up while the vehicle is stationary in neutral? Does the smoking decrease?

    Well unfortunately these motors have a hard time with overheating and pulling the threads in the block. I would do a leakdown test with the engine cold and check to see if it starts pushing coolant out of the expansion tank (with the cap off). what type of head gasket and studs are you running?

    So the smoking is a continual thing?

    You schedule a leakdown test?

    Pull your intake and Downpipe off. Check for oil pooling on either side, and check the shaft play on the turbo. That's where I would start.

    While by all means not a bad idea conceptually, it's much easier to look in places like the intercooler for pooling. The bearings are not in question here, just the seals.

    Though, iirc, there is a known seal issue on the intake side... which would resultantly render this turbo useless and in need of a rebuild. The OP has a blow-through MAF
