yo my ka-t has been having some low oil pressure problems, like its fine until it warms up all the way anywhere between 50-75psi then once its warm it works its way down to 25psi at 3,000 rpms in 3rd gear. i replaced the oil pump about 2,000 miles ago hoping to fix the issue, its an oem nissan full kit. i changed the oil to 10w30, and changed the oil filter as well. i cant figure it out, any insight. btw the motor was just rebuilt about 5000 miles ago....

do you have a dented oil pan? maybe the oil pickup is pressed up against the bottom of the oil pan restricting flow.

it is a little dented but not too bad, i'll take a picture tomorrow morning before work, thats the only thing i can actually think that would cause it... but at the same time wouldnt it do it all the time, not just when warmed up?

get a new oil pan anyways, especially if it the dent is in the middle or near the middle. a little dent can cause a big restriction. thats how my sr went out. spun 2 rod bearings.

ok, is there anything else this could be other than the pan, just wondering so i can try different things, since it's a bitch to take the pan off the ka while its in the car, so i dont want to take it out and fix it if it really isnt the problem....
