All,

Hopefully someone else has had this issue. I was towing my camper the other day and the truck lost oil pressure then died. It wouldn't crank like the engine was locked up. Ended up getting towed back to the house 93 miles. Then took my older Dodge on the trip. I just got home and went to see what was up with the truck and figured hey why not try again, in my mind I was in for a rebuild. The truck cranked slow and was hard to crank. Then it just fired up. Runs smooth with a small tick.

 

I hope you put oil in it?

If you lost oil pressure, how is it now???

 

The oil was just changed and was and is still full. Low oil was not the cause of this. Currently the oil pressure is great. Right above an 1/8 over halfway which is where it always was.

 

Wonder what happened to it......

Trouble is, if it happened once, it'll happen again. Not good for the engine......

 

A gauge indication followed by engine shutdown is cause for concern.
If low oil pressure was caused by engine wear, then it would be constant vice intermittent.
I'm thinking one of two causes; electrical, or, clogged oil passages/filter that cleared themselves out.
Rec check all battery grounds. Also check them for flexibility as they can deteriorate under the insulation.
Clogged oil passages doesn't explain the shutdown though.

 

Thanks for the recommendation. I will check all of that and see if there is a problem. I cannot explain the loss of oil pressure then the shutdown. It doesn't make since. If the oil pump was electrically ran then maybe, but seeing how it is a mechanical pump I have no idea.

 

Pull off the oil pan and check to see if the sump pickup is clogged.

 

That is on the agenda for this weekend.
