Update: The guy that built the motor installed the gear on the cam that runs the oil pump
backwards. Surprised I had oil pressure to start at all. Not good.
Thanks for all the advice. I have a feeling it`s the knock off pump you described as he bought a lot of parts from Speedway. Pulling the motor the next day or two and bringing it to a reputable shop in Minneapolis. Thanks again, Dave
Bored and stroked, I was surprized to find how dirty the oil was after not even five minutes of run time ,if that. The old builder had to miss something,to bad he passed away last year.
