Has anyone considered the possibility, that the problem of wiped cams is not so much the oil, but the quality of the parts (cam, lifters), themselves? I have never run a roller cam, only flat tappet cams, in every thing from small blocks from all three american auto makers, to big blocks, and six cylinders. I have never wiped a cam lobe. I also have not run any cams that have been made in the last 10-15 years...QUOTE]
I'll bet poor quality parts are a big contributor. So much stuff if off-shored these days, and you have to wonder exactly who's checking the materials and heat treatments.
