My 2006 scipn tc has 34000 miles, 15000 oh which have been supercharged. I’m running a 10.5lb pulley, with a tuned aem f/ic piggyback. I did my last oilchange (redline 10W30 oil) last weekend. During the week I noticed a loss of power, especially out of boost, smoke (I think it is white), a flashing check engine light, and the oil I drained from my catch-can looked like chocolate milk.
Head Gasket? I’m thinking maybe, except I have not yet noticed a drop in coolant levels. The car also idles poorly now.
I have not yet had the chance to do a compression test either.
If anyone has suggestions, or any input it would be appreciated!! Thanks.
