Ok I have had this problem for a while now but I never really posted it because it happened few and far between but now since i got my car tuned it has happpened twice in 2 days. I keep breaking rocker arm studs. I was told by boosted performance that my pushrods was the wrong legnth. Now how do I get the right legnth? I know they make something that looks like a pushrod that you can screw to find out but i dont understand how you measure it with the rocker arm on there. You would have to have the rockerarm adjusted to have the right legnth right? Well how do you adjust the rockerarms without a pushrod lol
