I just bought a 1998 dodge 2500 v10 with a engine noise. Coming from top end on the passanger side. It is a strong ticking noise. Any ideas. Im thinking its a bad rocker. Truck does burn oil at start up which i am assuming its an oil seal because it goes away when warms up. Also has a miss...that could be related or not. Anyone have this issue before....please tell me what you think it maybe. Is it hard to take off valve cover. It looks like ;you have to take the intake off first.
