Defender of the Universe
Ok guys here are some specifics. At start up my oil pressure is 40 psi @ idle (cold)and I can peg my VDO oil pressure gauge if I rev. After the engine warms up my pressure drops to 8-9 psi with engine idling 800rpm (hot). When the engine is warmed up my oil pressure while driving is 14 psi at 1200rpm, 16 psi at 1500rpm, 21-22 psi at 2000rpm. If the car kicks down to 3rd or I just build speed the oil press rises with rpm staying just above 10psi per 1000rpm. THE CAR HAS A BOOSTER PLATE ON THE OIL PUMP. When the new front cover was put on new oilpump gears were installed also. I also put a new oil pickup with screen and new gasket at this time. Why does my pressure differ so greatly hot and cold? I know oil thins as it heats but should I see this much of a difference? I use non synthetic 10w30. Steve you mentioned teflon from timing gears but I have a double roller set installed. The front cover is the one that takes the front seal from the outside (front) of the cover.
