OK guys, i get the point! I'm doing it myself!
Wayne: I actually ordered gasket-kit and adjuster tool from Pelican one week ago, but i'm still waiting for mail with my shipping options. (It's going over to sweden, you know) Order number is 1000999515-XXX.
How do i know i need valve job? I just tracked down and fixed all exhaust-gasket leaks (which involved lot's of helicoils, mind you) ... now engine is so quiet (well...as quiet as it can be with dual-pipe sport-exhaust) that i can clearly hear ticking sound all a way in in the cupé. It's quiet when engine is cold, but it starts ticking after few minutes. Yeah, i don't really know if it's valves , but it sounds same as ticking originationg from a friends 930, just louder. Also, gaskets are leaking and previous owner was a ***** who just drove the car for 15000 miles without adjusting valves (he was a pimp-type guy).
I'm doing it as a (preventive) maintenance. Bout things that need to go off...well i'm planning to remove air-filter box, and maybe intercooler to get more space for fixing upper valves.
