broke down on the way to the tire shop

[fatboyracing]

So I was driving to drop the truck off for new tires in the morning and

I get a message to shut engine off for lack of oil psi, and psi gauge is way low. So I pull over shut down pop the hood check the oil level its full.

I am 1 block from the tire shop so I start it up oil psi looks ok drive the block park it at the shop. I looked around the engine the little.All that I could see in the dark was what looked like oil on the oil cooling line near the radiator.

The fact the oil psi dropped and it looks like I have a leak has me confused. I would of thought oil sending unit but know with the leak Idk

Does not help it is 7 degrees outside

Any Ideas

So I can sleep easier tonight

Sorry to hear that.
See if there is a puddle in the morning. Ask the tire guys to see if they can identify the leak while it's up in the air. The leak might just be coincidental though. If the sending unit isn't faulty it could be the oil pump is a goner, thus the low pressure but full reading on the dipstick. Depending on mileage, the oil pump may be the culprit.
You could always throw a new sending unit on there and see if that corrects the problem. That's fairly cheap and quick.

What kind of milage do you expect on the oil pump I am at like 70k

way more then 70k

Ok I was sitting here stressed out so I got dressed drove up here and looked around with a flashlight for a few all I see is these two oil lines with oil on them what is weird is I also notice my coolant level is low
This is a real long shot but any chance with the weather being so cold and I have not run it for 3 days that somehow the radiator froze or something causing the leak? and actually caused the pressure to drop I also started it up and let it run for a minute I saw no leak and psi looked ok

Seepage from the oil lines isn't unusual at higher mileage. That needs to be addressed though. Cold weather can put your starter and battery to the test but once the motor warms up everything should function as normal. Even if you had weak or no coolant and the radiator froze, it's no different than a stuck thermostat. It won't affect the oil pump. Did you open the radiator cap or squeeze the hoses? Does hot air come out of the heaters vents?Regarding the coolant level, was the overflow tank empty or below the "add" line? When you pulled the dipstick, was it just oil on it or was it white or creamy colored?
Also, Check the connection to the sending unit. Make sure it's clean and tight.

Or it could be something as simple as the stepper motor for the oil pressure gauge going bad.

I should of updated this but I took it home and changed the oil psi sending unit

I need to order the oil cooler and transmission cooler lines

You can fix those with out ordering new. You will need a hose clamp for each end and a can or two of brake clean.

Use a dremel type tool to cut the aluminum off over the ends of the hose.
pull the hose off of the end --- Expect oil to come out.
Clean off the end of the metal tube and the hose very well. --- The better it is cleaned, the less likely it will leak.
Put it back together with a screw type hose clamp. Tighten the clamp until the rubber is just beginning to bulge through the openings in the clamp.
Rinse and repeat for each end of the hose.
Problem solved. For a few hours of your time and a few dollars in screw clamps and brake cleaner.

Another option, and one I would take if I weren't going to perform the fix above. Take both hoses to a shop that builds hydraulic hoses (some Napa stores will do this) and ask them to replace the rubber part of the hose. They do much better connections than factory and have never had one fail.

Excellent suggestion!!
