oil pressure problem

[Kenney Kelley]

This might not solve your problem but here are two things you might think about. # 1 Do you have the proper gap between the pick-up and the bottom of the pan ? #2 Do you have a couple of coils in your oil pressure line going to your gauge? Kenney Kelley

What kind of oil pan do you have...some oil pans are really bad and will let the oil go to the front of the pan as soon as you let off and hit the brakes...how many quarts does it hold and how many do you use?...just trying to eliminate things...Luke

ok heres what ive found. we took the drain plug out of the oil pan. ran a clear 1/4" hose into a threaded adapter and installed it where drain plug goes, measured normal oil level, then i started it up and kept quick reving it to get the pressure to drop. when the pressure dropped the oil level in the tube droped to. when we measured the difference its only leaving a 1/4" of oil in the pan which is how far the pickup is off the bottom. it also starts pumping air into gauge. ( we put a clear tube on it to) so. Im going to throw a std volume pump on it. and remove the trap doors in my oil pan. if that dosnt work i will remove the plugs out of the lifter valley. at least it appears to be a cheap fix. not bearings.

High volume pump? There might be your problem it sounds like its sucking the pan dry faster than the oil can return. I dont know about removing the trap doors though. thier job is to keep the oil in the sump on deceleration to prevent uncovering the pickup just make sure they are working properly ( IE they are not stuck shut). You might just fix one problem and create another if you completely remove them. If it were me I would try one thing at a time untill you figure it out. And it sounds like you are doing this in the car. But if you have it on a stand dont roll the engine upside down and then install the pan. Reason being on some pans it will cause the trap doors to open and stick. Moroso and others recomend the eninge be sitting up right when the pan is installed to prevent this. Good luck and let us know what you find.

i already pulled the doors out. i really think that as sticky as the lucas oil is it was holding the doors a little. i went ahead and removed them because its so hard to drop the pan on this car with it in. i still have plugs in the lifter valley if this dosnt cure it i guess i will remove some of them or go to a thinner oil. i really think the std pump will help a lot if not fix completely
