I have a problem w/both my screw blown 481x's, Both of them have the pleuger pumps,Dan Olson oil pans,Steffs dry sump tank, 16 quarts of oil. With the oil tank filled apx.5'' down from the top, when you start the motor the level will fall some and not refill, Ok,The big thing is after making a 1/8 mile hit and letting the motor idle allmost to the end of the track or clicking it off early, the oil tank is allmost empty and I have to take the diaper down,Drain the oil pan,and refill the tank,every stinkin pass! Terry at AJ's said with a screw blower it's the nature of the beast and something about the boost created, the oil suction side can't keep up. Other than switching to the daily dry sump system, is there a option in a bolt on pump to replace the pleuger pump that will keep up with the suction to refill the oil tank ? Is there a wet sump setup for the AJ 481X so i could posably do away w/ the dry sump? Draining the pan every pass sucks, Please help.
