I have a 90 5.0 and when i first start it the oil pressure gauge will be in the middle but then when the car warms up it will read low until u get on the gas and when i was doin donuts it started makin a loud tappin noise i think from in the oil pan but then if you turn the car off and let it sit for 10 min and then turn it on it will be gone but the oil pressure gauga will be low so im tryin to see wat it can be any info would help thanks

Did you check if you had oil in it to begin with?

If you are losing oil pressure when the oil warms up try running thicker oil. Could also be a bearing (main/rod/cam) is worn and has a greater tolerence so the oil pressure is now lower.

If you get a tapping noise then you for sure are losing oil pressure. Is the oil fresh? Did you do any head gasket work recently? Check for simple things like a crushed oil filter too.

Thicker oil will help but you'll need a rebuild time to call Turbo50. 20-50 or that molasses like oil will work for a little bit but It gave me time to have Dan build another motor.

that loud tapping noise is your rockers going dry, meaning theirs no oil circulation. try thicker oil like they said and if that do not work then your oil pump about gave up.
