Anyone know? it is a 88 T2 and I am losing oil pressure in 4th and 5th gears but in 1st , 2nd, 3rd its perfectly fine. Anyone know wtf is going on. ?

What is the oil pressure reading for the same rpm in each gear? The same vehicle speed will result in lower rpm for a higher gear, hence, somewhat lower oil pressure. If the pressure varies at the same rpm in each gear, then, you've got one weird problem.

Ok here is all the crap... First his car is idling at 15psi you hold it above 3k rpm's on idle it will raise to 60psi. And then the driving comes you drive it and it will go above 30+ in 3k+ rpm mode but never reach 60 .... and then if you let off it drops straight to 0. Not fast but slowly. It does it in all gears and I cleaned the sending unit.

BINGO

Wrong front cover gasket was used. You have a leak/bleed through on the front cover oil O-ring.

Yea it was rebuilt supposdly by mazda GOD KNOWS if they do but me and my friend are schedueling a day to remove the front cover and replace all the stuff that might have come out on the front cover and also change his oil filter and get him a aftermarket gauge. For sure.
