Has anyone experienced low oil pressure due to wear of the Renesis oil pump?

My Renesis engine on my RV-7 has had decreased oil pressure for a while.

I changed the oil pump and now my oil pressure is back to normal.

I have 780 hours on the engine and about 2500 engine heat cycles – most of my flights are very short.    On takeoff with relatively cool oil the pressure went to 80 PSI but as the oil heated up the pressure decreased to as low as 65 psi on a hot day during climb out.

I change the oil at 50 hours  I always inspect the oil filter material and had some very small shiny flakes in the pleats.  The particles appear to be non-magnetic

A month ago I decided to remove the engine and replace the oil pump.

I found the aluminum oil pump housing had a slight amount of wear where the steel  pump gear seals against the housing.   Replacing the oil pump has resulted in much better oil pressure.
