Well, I searched and couldn't find the same problem so here goes. I noticed today that my oil pressure is going up and down. 1980 c10 2wd with 350. When I'm at a stop with the truck in gear, the pressure drops close to zero. I put it in neutral and the pressure comes back up to just under the half-way mark. When driving the pressure is just under the half-way mark also. The guage is stock. I'm not sure of the age of the sending unit or oil pump. Any suggestions?

I heard so dont qupte me on this but a bad pump can cause this if its about to fail

Well then it probably wouldn't be a bad idea to go ahead and get one. Thanks!

I would check the sending unit, and gage first. Allot less work!

Blazin, thanks for the advice. Since there aint no noise and the engine aint runnin hot, prolly not much to worry about. Right? I need a day or so to get a new sending unit. (the bell shaped by the distributor, right?)
-
Yes.
-
had the same problem with my truck. turned out to be a bad sending unit just as blazin said
-
yeah yeah yeah whatever lol ::)no go with what they said i don't know why but that should of been the first thing that i said.
-
hey who knows i guess i was just hoping it wasnt a bad pump ::)

Replaced the sending unit today and seems to have fixed the problem. Oil guage reads around 12-15 at idle and 30+ when driving at highway speed. Thanks for all the advice. Now, what will be next?

Guage will go from all the electrons that are correctly flowing thru it... :D
