I am hopefull the rattle is one bad pre, and pray the GP ( which are working well btw) comes out of that cylinder! I wont mess with it for a few months.

Must say that I dont really want to change the cam timing. Car pulls strong ( as well as a turbo I should think) and gets over 700 miles on a tank w/o AC just under 700 with A/C on nearly all the time ( like now). Sure dig its hum when its runnign smooth!

Putting this lil' black girl on a diet next week. A biodiesel diet. See how it likes that cetane rating. Dont know where I'll start though 50% 20% 70% ??? Buying a few fuel filters in anticipation, and trying to identify a few good sources for my " WINGAS" !
