Chev 216 Oil Pressure

[Ken Thomas]

Hi Phil, the speed of the camshaft and distributor is half the crankshaft speed and I allowed for this. I cannot understand that the relief valve can't limit the pressure to 15 PSI for whatever reason. I can only assume that for some reason the tightness of the bearings etc is causing some kind of pressure behind the valve ( I have seen this in other types of motors). I will push on for the time being until I have rebuilt the starter motor & then turn over the motor at the same time as spinning the pump. I will check the dipper sprays through the fuel pump mount. Will keep you all posted.
