Re: no oil pressure when stopped

it could be a simple oil pressure sending unit issue.
buy a cheap mechanical gauge, or replace the sensor.
problem persists, its going to be worn oil pump, cam bearings, or main bearings.
doesnt sound like it needs to be your DD at the current time.

na i still got my dd as another car but i wanna check it with an oil pressure check (forget the name friend has it) but it might be my oil pump my oil pans pretty banged up so i guess it might have damaged the oil pump i wanna buy a new one anyway so if the problem persists then its the gauge
