I don’t buy that, it's a Roller Rocker. How can it push latterly? I think it’s bad machining from the start.When you align the rocker on the top of valve the rockers are pushing the valve out before it descends down. Their for wearing out the valve guide prematurely.
I still say BDM should be swapping them out!!!


it don't matter.I've seen all 4 guides,and on some less.I still change all 4 on the heads that have the problem,even if it's only 1 bad one.:up:
