Hi Rob,

Not an expert by any means, just a Ford guy building and modifying all types of race engines since I was 15. Dad had an auto shop, and I got my Physics degree.

Details are very important to understand failures. Lowering valve spring pressures
to rediculous low values is not a fix for (allegedly)poor cam quality or poor cam lobe lubrication.

I have suspected for a long time that CVH cam problems are a direct result of inadequate
oiling to the lobe.

Other engines have had similar issues. One being the early Porsche 911 2.0 six. Early versions had oiling through hollow cams to holes in each lobe. Latter versions had oiling spray bars in the cam housings.
Pinto race engines (and Datsun L20B's if you are old enough to remember that one ) use oiling spray bars to enhance camshaft lifetimes.

Solve the camshaft oiling issue, and you will solve your camshaft wear issue.

I know I am not one of the CVH "Gods" on this forum, so many will probably dismiss
what I put forth.
