An Abberation in Cam wear - ZR-1 Net Registry Forums

Dynomite · 12-10-2012

With several posts recently discussing Camshaft wear on associated mating surfaces (Head and Cam Cover)......here is a new aberration to think about

This is a low miles (less than 30K) stock 90 Head.

The tips of all the cam lobes (8) on one intake camshaft (the other camshafts have a perfect wear pattern) of one head are shown here. Can this be explained in terms of cause and effect?

The two photos are taken on drivers side Head with front of engine toward the right.

The lifters related to this camshaft seem to have a normal wear pattern.
