m1009 Oil Pressure Light

[boe403]

Howdy All...

Just acquired an M1009 recently, 48000 miles, starts and runs, Noticed the other evening that OP light would VERY dimly be on at idle. Started looking further, upon starting light goes off, but again VERY dimly will come back on while idling, both warm and cold. Could this be a faulty sending unit?.. (BTW, I despise Idiot Lights!!).. Is there a prefferred pressure gauge that I can install?? Also, I looked for the location of the sending unit, didnt see it (Tho didnt look REAL hard). Where IS the sending unit located on the engine???.. Thanks...

The oil pressure sending unit is on the drivers side rear valley. Right behind the head.

Have you downloaded the free technical manuals? They have the troubleshooting sections, parts manuals with diagrams and GM part numbers.

It could be a simple as needing a new sender or a painful as the bearings being bad. Without furture testing it is just a guessing game.

Just about any gauge will work. Many guys will keep the light and add a mechanical gauge.
