I took off my intercooler and found what i suppose is a normal amount of oil slick from overfilling oil, which i have done before, plus there was some old thick black layer on there.
I went ahead and installed a DIY oil catch can off the rocker covers and PCV, and cleaned out the intercooler, sloshing gasoline around in it and hosing it out. I was pleasantly surprised that cleaning the intercooler gave me a better idle-> cruise throttle response. I was wondering if there was any sense in trying to clean out the rest of the induction works between the MAF sensor and the turbo itself,or even inside the throttle body/runners. Any sense to eliminating the existing oil slick layer in there.
