Does anyone have any idea why my cam won't come out without pulling the engine? Meaning why won't it come out from the front like it should (easily) could one of my bearings spun? Or did one of my cam lobes grenade thus preventing it from being pulled out. I can turn the cam over and over but it won't come out more than six or seven inches, it will go back in the engine but it still will not come out. I was wondering if this has happened to anyone before....and did they have to beat it out from the back with the engine out?
