dont trust the stock gauge , go buy a cheap 15$ mechanical oil presure gauge and hook it up temporaily to verify oil presure

to hook it up u can unscrew the stock sending unit above the oil filter and hook the mechnical gauge in its place

Hi project89.
I def will check with a pressure gauge. There are no knocks or ticks in the motor so.. I cant see it being the motor. I would think different if the gauge did not jump up when ya hit the gas. It has a stumble when ya first hit the gas but seems to run fine when if ur on it.

so im pretty sure i may have found the problem..lol or part of it..
the sensor by the oil filter (oil pressure) i think. was barely threaded into its base. also had a small leak from there too. seems better since i tightened it.
