| 66' Fairlane 390 GTA engine oil pressure(update) |

Thank-you all very much for your responses. I installed the liquid-filled mechanical pressure gauge at the filter and noticed no improvement in pressure. It reacts quicker than the cheap gauge and I'm still waiting on the Auto-Meter unit. I talked with the engine builder and he said the oil pump he pulled out did have a stuck relief valve in it. I asked him what clearances he had on the rod/main bearings and he said .0025" on each. He said he put in new cam bearings. The pump that is in the car is a Melling high volume/hi pressure with a new stock oil pickup. I asked him if the oil filter could be defective. He said it is possible but hasn't experienced any with Motorcraft FL1-A filters. I asked him if a oil gallery plug at the front of the engine or on the rocker shafts might be leaking. He said it most likely would be the one behind the cam gear if any were leaking. I told him I would change the filter and put in new 20-50wt. Valvoline oil and get back to him. He said if it didn't improve that he would come down and pull the motor and repair it. Makes me feel good he is standing behind his work. If it does have to be pulled It will be a bummer since it sounds very strong and I have never heard the lifters make any noise either. Any more ideas anybody?
Thanks! |
