I'm going to move this to "General Technical Chat" since the first thing needed is to get this running right.
SVT upper cam cover
This thread from the SVT performance area will give some info. on the VCT.
Cam belt is extremely important on these since valves WILL be bent if it lets loose.
Posting in general tech for repair problems & SVT performance for upgrade info. will make your questions easier to answer.
P.S. - Welcome to FF!
