Traveling along the Mountain Loop highway I had noted the sound of misadjusted rocker loads. I had heard this sound before, and in fact had just done a valve adjust the morning of. I had hoped that I simply had a rocker nut that was loosening up, so got on the Internet and ordered up some polylocks. It was a bit far fetched, given they were brand new rockers pushrods and nuts, but that’s what hope and denial will do to you. Somewhere in the back of my mind I knew that was not going to do it, so when the polylocks arrived I committed to pulling a rocker or two and doing a close inspection.
The results of that inspection were pretty conclusive. My pushrods were eating themselves at the rocker arms. The worst had eaten clean through the welded ball of the pushrod end. Clearly, this is going to be a problem.
Next up was valve geometry. Which was perfectly centered across the valve stem. No problems there.
The plot thickens.
