91’ f-150 5.0

During the winter the water pump pretty much exploded. Thank fully it was so cold it never overheated. Got it fixed and it has been parked for the last 5 months. I was waiting for a non raining weekend to pull the tranny and replace rear seal and tranny pump seal. That sucked because it was one piece.

Got it it put back together took it for a drive and noticed after it warmed up I had some noise almost a rattle. I pulled the belt and I thought it went away.

It it seemed like the bearings in the alternator were maybe going out. So I replaced.

Not it! Well it might have been something, but still have issues.

Oh oh when I drained the pan it was full af water. I am thinking from when the pump went out.

I noticed a time or 2 it was like the engine had a hiccup. The oil pressure gauge seemed to have a very slight fluctuation. I don’t know that I have ever seen it or my other Ford fluctuate.

If the shop used any rtv they didn’t let it cure befor filling with coolant. It leaks. Going back.

Back to my issue is there a possibility of the oil pump going out?

Has anyone experienced an oil pump go out?

Could i I have another accessory trying to lock up?
