Oil pressure gauge flipping out.......

[sweetwaterbroncoII]

My oil pressure gauge keeps going from normal to low normal to low normal to low.....could the gauge just be going bad...I have bought an aftermarket gauge to install, but I was just curious if the factory ones go bad?

maybe is not the gauge, maybe the sender unit, i have some issues with mine too, it goes dead when the truck is cold, once the engine warms it works fine. check your sender unit first

True...I was just curios, I'm replacing it this weekend!

did you get a manual gauge?
if so pick up some plastic wire loom to run the line thru.

 

[sweetwaterbroncoII]

Yeah I got a manual gauge...but I also bought copper tubing so I won't have to use the plastic tubing....do I still need the plastic wire loom?

 

[Wicked_Sludge]

you dont need wire loom for either, it just makes it look nicer.

and protects the line from getting a hole rubbed in it (insurance).
don't like the copper line,Ive used the plastic line for more than 20 years in almost as many vehicles with no trouble.

 

[sweetwaterbroncoII]

I heard that the plastic line could melt....is that a common problem?

 

[Wicked_Sludge]

only if you let it lay on your exhuast manifold

Cool...I understand!

once i used a oil pressure gauge but mine was electric i just replaced the bulb with the needle gauges bulb and connectedthe wire, its easier to do

Easier to do, but you essentially have the same guage as the stock unit. If I can have a mechanical unit, I would much rather use it than have an electrical sensor telling me what it thinks the pressure is.

I put in a mechanical guage with the plastic tubing over 2 years ago and it's still working fine.
