Have a question for anyone with an idea. I bought a 89, lx coupe with a b303 cam, 1.7 rockers, crane cams valve springs, and stock heads. The car has been sitting for a couple of months. The car was one of my friends and he had it running fine for a year. He then sold the car to someone else that said he ran the car to 6000 rpm when running hard. He then broke a valve spring on the driver side on the #8 cylinder. I can't remember if it is the intake or the exhaust. The same one has broke 3 times now. I am just wondering what could be causing it. If it could be the pushrod, valve, or just over revving it. Any ideas? Just wanted to have an idea before I dig into it.
