Trying to diagnose scion issues...

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.

sounds like gasket. have compression test done.

blinking light = misfiring. chocolate milk = oil and coolant mixing together. loss of power with the combined symptoms = usually a headgasket.

You sir need a head gasket.

head gasket…ftw
