Re: IML:oil pumps



Just some oiling facts, the standard pump supplies more than an ample amount of oil to the engine. If engine clearances are in spec, the oil pump actually "dumps"more oil than the engine needs, through the pressure relief valve. Installing a high volume/high pressure pump will "dump" more oil, and add to crankcase oil temperature. On racing, high performance engines, the clearances are increased, that helps to reduce friction, but also carries heat back to the oil pan. Larger oil pans with more oil capacity as well as helping to dissipate heat are used. The minimum standard rule is: 10 psi for every 1000RPM. So if you have a worn tired engine, and it meets that spec, you're OK for now, if you just rebuilt and thats your spec, you did something wrong. On the Chrysler type pumps, there is one problem. Since the outer rotor is forced against the housing (by the oil pressure) the housing wears in one general spot, along with the covers. I've had high mileage motors that would loose prime, after sitting for a few days, or it would take a bit of time for the light or gauge to register. Just some food for thought. Ya'll have a nice day, Dave.
