oil pressure gauge not working-6 cyl
Finally got around to swapping my oil pressure sending unit to mechanical instead of idiot lights. I ran a line from the block to the gauge but I'm not getting a reading. I can see the oil in the tube but no swing to the needle.
When i shut the truck off the line is oil,air,oil. But when I rev it up the oil goes all the way to the gauge. What's the problem? Picture is with motor off.

Re: oil pressure gauge not working-6 cyl
I'd bet that the gauge is bad, since it looks like oil is getting in the line. Don't worry about some air in the line, it makes no difference. I suppose you could unhook the line from the gauge and crank the engine(don't start it, could be a big mess) have a catch can ready and see if oil is getting all the way there.

Re: oil pressure gauge not working-6 cyl
I can watch the oil go all the way to the gauge when the engine is revved up, but it never moves.
I got out and ran in 3rd gear wound up,should have been max pressure.

Re: oil pressure gauge not working-6 cyl
Thats why I think the gauge is bad, Since oil is getting to the gauge and it doesn't read anything then the gauge is bad.
