Wear on valve stems

Mate a fellow sandgroper , you're the first one I've come across on the forum! Sounds to me you may need to replace a few parts (thats the problem when you do strip the motor) where do you stop & how much coin you gotta spend ! Get a good manual that will help with most jobs to be tackled . If something doesn't look right usually its not . There is some good info on the Porcshe tappit upgrade on this site too . I've only had this SR for 2 years I purchased it off a dude in Wanneroo for the right price in a lot of bits but licenced but mechanically it seems OK so I aint fixin nothin if it aint broke cheers from Dave in Dunsborough .
