86 3.8l Looses Oil Pressure

[86BIRDMAN]

3.8l 86 Bird Looses Oil Pressure When Engine Gets Hot. When Its Cold Its Fine. Drive It On Long Distances And The Idiot Light Comes On And Looses Pressure When I Stop At Lights Or Stop Signs. If I Keep My Foot On The Gas It Seems Ok.

the first thing you need to do is determine if it's actually losing pressure by hooking up a mechanical gage or replacing the sensor. you could try using a heavier oil. oil pressure problems are usually expensive to fix the engine bearing clearences might be to big or the pump screen clogged/ worn out pump.
