I really need some expert advice here. The issue is a scored cam lobe.
In replacing a leaking
oil pan gasket, I decided to look around a bit and found the pictures attached. Two witness mark grooves on the cam lobe, in at middle of the motor. Does this look like a roller failure or about to be a roller failure. I could really use some experienced advice here.
Facts as I know them: Bought used, so the internal motor info is not verified, yet.
Motor is a 418 sb, roller Comp Cam, but unknown specs.
Motor made 510 at the wheels, so I guessing the cam is a bit lobe radical.
Rev Limiter is at 6,250[img]
If pictures of the top end valve train would help, I can do that.
Frustrating, I just wanted the tiny leak to stop. Better here than the side of the road I suppose.
Thanks of the help!
