Recently, I, with the help of a friend, installed another stock short block in my 87 turbo. (I shattered one of the pistons) The guy I bought it from said it only had like 70k on it, but I think he was full of shit, because it only has like 40-45 psi oil press at 80mph, and only slightly more than 10 at idle. (With 20W50) I used my old oil pump, pickup tube, oil filter housing, and oil control nozzle thing between the block and the head. With my old short block, I would have 20 idle/60 psi cruise with 10W30. WTF? is there anything other than main and rod bearings that could be causing this? When I start the car, the gauge creeps up very slowly to full press, around 70 psi when cold, when it used to jump up very quickly. This engine's code is BS instead of A20A3, now I know what that stands for, BULL SHIT... If any of you guys have any ideas, let me know, thanks
