I got the pan off and found chunks of gasket material in the pickup and in the pan. I was able to scrape some out of the pickup with my finger tip and there is a piece hanging on in this picture. This does not surprise me since I have made three cam swaps with this pan in place over the years.

My next move is to check the bearings.

Note: The existing pump has a HV tag and has been in this engine for 22+ years but only about 5-7k miles.
