Re: Oil Pump Test
Back in the early 90's when I started rebuilding engines for sale I used Mellings new pumps. I had to replace several because of low oil pressure. These pumps had a number of problems that I hope have been corrected by the manufacture. However, I've never used an aftermarket pump since. I have JWL test the stock cleaned original. Lately I just clean them and inspect for end play and reinstall. And yes, the original early pump works very well and not having a relief valve is aplus in my opinion as this is the cause of heat in the oil. Placing the relief valve at the end of the oil supply line insures the engine of better oil flow and less heat. JMO
