Massive smoke issue...HELP!
Ok I recently bought an 88 turbo II with a s5 engine, turbo and manifolds. When I picked the car up it smoked a bit but quit after a short warm up period. I suspected the turbo was the culprit as I was told the engine had been rebuilt recently. (I had concerns about the quality of the rebuild for various reasons but the price was right) After doing a few test drives and tightening up quite a few loose nuts, bolts, etc. I wound up with a massive oil burn problem, to the tune of 1/2 quart in 15 minutes of gentle driving. I have now checked the turbo (cold side) and pulled the UIM off to get the turbo out and check the wiring under the manifold. The cold side of the turbo was pretty clean as well as the rest of the intake path. Shaft play was minimal and the turbo spins freely so I don't think its the problem but my turbocharger experience is limited so I may have missed something. All 4 of the plugs do have some oil on them but not nearly as much as I would expect considering the quantity of smoke coming out of the tail pipe. Could it be the hot side of the turbo? How would I go about nailing down exactly what the problem is? If it is the rotor side seals can I replace just those seals and what would cause them to go out like that?
