Oil On Maf? Cleaned MAF! NOW Car Running To RICH. HELP!!! check sig for details on car. but i recently had some dyno tuning done. i was getting oil out the tailpipe on high boost when it was on the dyno. i thought i might be getting oil on the intake side, so i took the pipe off the throttle body and pulled the pipe with the maf and it was covered in oil. ok so i got the oil problem cleaned up. cleaned maf with electronic cleaner. now the car is running very very rich. car bogs down, hesitates smoke and exhaust smells funny. maf seems to be reading everything ok. any suggestions or do i just need it retuned? tried to lean it out with my predator but not helping.......

Sounds like your getting excessive blowby...I dont think tuning will cure that. What does it look like when you take the oil cap off at idle? Choo-choo train? I would get a leak down and compression test done and see what shape your engine is in. I started having the same issues...I wont know exactly what is wrong until I tear it apart but my #7 Cyl def has some oil control issues. 402 is on the way!

the engine is fine. it all stated with the oil coming from the turbo. i believe what was wrong with the turbo was i didnt have it clock staight up and down it was sitting at 11 and 5 instead of 12 and 6 so i fix that and rerouted my return oil line to the pump. once i got all the oil out of the pipes and back on the car, and cleaned the maf with electrical cleaner. when i start the car it runs real rough when the air pump is on. when air pump turns off car smooths out but is still running really rich. i have a wide band hooked up. the AFR are dropping down to 8.7 to 9.3 when just cruising. i cant get on car at all bogs down and hesitates.

If you're running a MAF, and the tuner did any sort of a MAF tune while it was covered in oil, it's now sending different data to the PCM. Re-tune it.
