I was traveling down the interstate, when I lost power with what felt like a miss. She stalled on side of interstate, and would not start. Towed it home and discovered water in the oil. There was no noise, no smoke, and no loss of fluid under car. Can someone please help figure out what happened?

 

Start with a compression test.

No need to, when I checked, there was water in the oil. 😪 it has been slowly losing coolant since I bought it. With no leaks showing, I can only guess it was that. I don't have money to send to dealership to have looked over, but I can go ahead and test compression.

 

There’s a couple of different ways water can get in your oil. One is a blown head gasket but the other is lower intake manifold gaskets, A common problem with these trucks. Since you don’t feel it’s necessary to do a compression test I don’t know how else to help you. I will remove myself from this thread and let anybody else who can help you do their thing. Good luck.

 

I agree with GeorgeLG that the issue could very well be a blown lower intake manifold (LIM) gasket. This was an issue with the late 90s 4.3 motors.

The failure takes the form of coolant leaking, sometimes catastrophically into the lifter valley with the oil mixing with the coolant. This then can ruin all of the bearing surfaces. However, if caught early and if using synthetic oil, the engine can perhsps escape being damaged.

 

I did set up to have the compression checked. I really appreciate e eryones input. I have put it up for sale for parts or to fix. If anyone is interested. Just hollar. Thanks again
