The cam and lifter seem to be perfectly fine. I did buy a replacement lifter for good measure.

I, too, have wonder if the push-rod was incorrectly hardened. On the other hand, once the clearance is too much on a solid roller, it's like putting a demon in your engine with a sledge hammer. Something is going to get the **** beat out of it.


I also agree that the roller lifter has had the **** banged out of it. I wouldn't trust it. I'm not a fan of solid rollers. I hope the cam lobe is good. It's hard to see through a lifter whole. I would NOT spin it with my finger in it, but I would want to. Move it then feel it, in small movements, for two crank rotations. Man that would suck.

With the powdered metal, I would pull it, disassemble it, clean it. After I cleaned it, I would clean it again and again and again. Then make sure everything that goes back in is good. I would inspect the cam real carefully.
