The roller rocker stud snapped on the exhaust valve. The exhaust valve was not opening and what a banging noise through the intake. I guess when the intake valve opened the the exhaust gases went through the intake and back fired. What causes a stud to snap. The poly lock was unbelievably tight! I cant get the broken stud out of the poly lock.
Also can anyone identify what roller rocker I have? It has a sledge hammer insignia, color is red
350, 3/8," 1.6
350 must be max spring pressure, 3/8 is stud size, 1.6 is rocker ratio,
On the bottom it reads SPL08
Could not post photo
Thanks
