Oil in the intercooler

[DJay]

Finally did the "spring cleaning" portion regarding cleaning my intercooler.

I was kinda surprised to find a thick coating of oil on the inside of the uppipe and on the inlet and exit of the intercooler. U don't wanna know how dark the carb cleaner was that i poured outta the intercooler! Even the sleeves that cover the connections from intercooler to upipe were saturated with oil.

Weird thing was ... no oil (and i mean NONE) on the exit of the turbo! Where is this oil coming from? Is there something terribly wrong with my car? Pls help!

TIA!

Do you have the tube that runs from the passenger side valve cover to the turbo bypassed? If not, thats where it came from.

Should i have it bypassed? I guess what i mean to ask is ... will it hurt anything if i DO bypass it?

Thx fer helpin out a newb!

Nope, it doesn't hurt to bypass. Being the "cheese captain", I removed the tube, stuffed a chunk of oil saturated foam into the factory breather elbow (after cleaning the factory breather), and zip-tied a black rubber cap on the turbo inlet hole. BAM! No more oil.
