also when i got the truck the breather was missing so the valve cover was open, is it possible dirt damaged something?

Are you sure it's engine oil and not trans fluid?

More likely to have water in the oil over your oil in the water issue.

I'd be checking both trans fluid condition and engine oil.

i belive its engine oil, its pretty brown in colour, there is a bit of water in my oil but looks way too clean to be coolant, my buddy was thinking its just condensation because i pluged a hole in my valve cover where a breather should have been. I think im just going to change the head gasket and what not.
