I got slick stuck on some ice this morning,,, I put it in 4 wheel drive and it took and I was going nowhere fast,,, I put it in into forward and backwards to try to get it rocking back n forth… I finally got some forward motion and I put the footfeed to the floor… I got out and then my truck just died.. it took a few tries to get it started again… I noticed on the way to my sister in laws funeral that my oil pressure was low,, it would go to practically zero oil pressure when I was at a stop light…. I went and got the oil changed after the funeral thinking it might be dirty or broken down oil… my pressure did go up some,, but now I hear a tick tick ticking… I don’t know if it’s a stuck lifter or what.
I’m not overheating, my temperature level is good.
Does that sound serious to you guys?? I know a few things about cars but
I’m not a mechanic.. lol.

How cold was the engine/oil when you "put the foot feed to the floor"?

No oil pressure and a ticking is a serious problem. Eric

To the OP , how much oil pressure do you have now ?

Put in a quart of trans fluid but don't over fill.......I heard you can run all trans fluid for some time to clean the engine....

It had been idling for about an hour.. I got up early to warm it up and to wait on the school bus with my granddaughter…we sat and waited for about a half hour and no school bus.. so I wound up taking her to school and then I had to really bust my chops and get a few traps checked..
I’d say it was pretty warmed up

What year is it and how many miles on it?

Did it have oil in it before? How long since you checked/changed the oil?

That may very well help a stuck/plugged lifter, but if its spun a main bearing that won't do anything good.

OP, is it a deeper knock, knock, knock sound or a higher tick, tick, tick sound?

The needle is fluctuating from the middle (40) to (20)

It’s a high tick

High tick would tend to point to valve train issues, not main bearing/crank issues. If you over revved it, a push rod may have bent. Lots of things may have happened.

What kind of truck/engine?

I check it every other day because it does have an oil leak. I really don’t remember when i last changed the oil. The blasted oil mileage sticker never stays on my windshield . but I went and got it changed today .

Push rod engine then. Could be a lifter, push rod, valve issue.

You'd start by pulling the valve cover on the side that is the loudest and looing for anything obvious. Or doing a compression test.

Correct. I concur.
That's a good engine.

Put a pocket notebook in the console/glove compartment and write down the mileage and date it was changed. That's what I do when I change my own.

It was used too much when it was new.

Does flooring it make you stop spinning the tires in IL? Asking for a friend that is going to drive through there.
