Just wow on the carbon build up!! I had to pull the head on my 944 turbo with a 150k miles and it was no where close to that! I cleaned my piston tops off with carb cleaner, a rag, and a plastic scraper. I do not know if premium gas had an impact or not, but when I cleaned my intercooler last year it was pretty oily from 25 years of air being ran through it. In fact, none of the turbo cars I have had the head off had that much carbon on the piston tops... Of course since I value my FI engines, I only run premium (93 oct and no ethanol).
I like coffee.
My e39 is fixed and moving towards atrophy.
