Hi guys, here is a chain of events of my problem :
1)Experienced misfiring/engine stalling but no BLUE smoke.
2)Checked plugs to find them all oily.
3)Compression test OK.
4)Removed stock airbox - MAF sensors, Filter, Hoses all oily.
5)Removed hose at Turbo compressor to find a pool of oil contained there (refer to diagram).
6)Removed intercooler pipes - more oil flooded in there.
7)Removed Turbos to check - exhaust side is DRY.
8)Blowby control valve - need to check?
9)Turbo oil supply/return pipelines, hoses - OK, no blockage.
Engine is FULLY a stock setup (including crankcase vent. hoses and PVC etc.) except for the N1 oil pump and Tomei oil restrictor in the Block.Prior to the rebuild, piston #5 and #6 cracked, and I forgot to check whether that could cause a residue of oil in the intercooler, which I did not drain out.First thing came to my mind was that the Turbo SEAL could be defective, but on the other hand, the exhaust wheel is DRY.
Secondly, would the residual oil in the intercooler be re-circulated back to the intake/turbo??
Lastly, I suspected that the oil could leak past the new piston rings but that would be very unlikely because compression test passed and the exhaust ports on the cylinder head are dry.
I am desperately seeking ANY help or useful INFO out there,and I really don't know what else to check or do because I just bought the car. Thanks a million and I would greatly appreciate it...
