Here is a good problem for you folks to chew on: Low or no oil pressure. I started my car up the other day. It made horrendous noises, so I shut it down immediately. I restarted it, and the gauge read "0" pressure....WTF.
So I do the following: 1. Check the oil level - full 2. Pull both valve covers - no issues with the pushrods or rocker arms. 3. Pull the distributor - the hex in the gear is perfect 4. I pull the oil pump shaft - No issues here So, I pull off the oil filter, and fill another filter and screw it on. I then proceed to put my oil pump priming tool on the pump drive shaft and spin it both CW and CCW. I remove the sender fitting, and spin the drill to get about a half quart of oil out. Put everything back together, and fire the car up - perfect oil pressure and no noises. I drive about 15 miles, and the oil pressure drops to about 15 PSI. I limp home and change the oil filter again. Fire it up - perfect oil pressure. Go for another drive, and after about 20 miles, the oil pressure drops to about 15 PSI AGAIN. So, here is my prognosis: the pressure relief valve is sticking due to debris or some other reason. Comments????? It appears that an engine R&R is in my immediate future......:( BTW - Oil pump is a Melling HV with a Milodon 7 quart pan.
