1995 chevy pickup studders when started and has rusty-like oil

I was driving home and my truck overheated and had to be towed to my house. Now its hard to start and when it does it studders and i checked the oil and it looks liquidy and rusty.

Please help!

Sounds like you have coolant mixed with your oil from a possible blown head gasket.

would that also cause vibration and a weird running sound?
