maybe its just my complete lack of mechanical knowledge,but how do you check the bolts on the car, i mean what bolts?engine mounts?
-----------------------------------------------------------------------------------
bolts on your manifold, wastegate.
Like "trik" said,
you need to use 94 octain
synthetic oil (any kind, oil is oil)
ya, should let your car warm up first(and in the summer that'll take, what? 5 minutes.)
if your driving under normal conditions you don't have to let the car cool down, but if your running it hard like hittin' the boost alot then let the motor run for 5-8 min. No big deal, buy a turbo timer and lock your doors.
