1994 F150 XLT 4x4 Extender cab 5.0L .
187,xxx miles.
I have owned this truck 7+ years. Lately I noticed on cold start up the oil gauge barley makes it to "N" on the scale. After a couple of miles it slowly
creeps to between "A and L". It stays there from then on regardless of engine speed. My concern is engine damage on startup.

Do I have a bad sender,gauge, or poor oil circulation due to sludge etc? The dip stick reads full.
Thanks in advance for any ideas.

 

Unscrew the sending unit and screw a mechanical pressure gauge into the hole and start it up. See what it reads.

If you are using a Fram or other cheap oil filter, toss it and put a Motorcraft, Purolator, or Wix on it.

 

The factory gauge is fake, but it can be easily converted to work.



Any needle position for the factory gauge, OTHER than zero & mid-scale, is an electrical fault - not oil pressure.

Only the oil gauge is faked-out. The rest work.

The picture was too small to see.
How do you convert it?
thanks

 

Click it.

 

Click it and it opens in a new tab the exact same size.

 

Then F150online is screwing up that link because it's formatted correctly. Try this one:

Yep - it's this BBS. They've changed the way images are handled, so probably NONE of the ones in posts that were working before will work now.


Yep - they're all screwed up now.

Steve FWIW you can still use the [img] brackets like you used to be able to. Just have to do it by hand

I hate the new image setup too, but I don't have any say in how the ownership IB handles changes

Thanks for the info.
