Looking at my dip stick, it is milky brown, It looks like a blown head gasket, but the car been sitting 5 years, and never has been ran, I brought the car and parked it, wiring harness was later eaten by a rat

Could this be from condensation getting into the oil? I remember when i drove it home it was back firing white smoke?

Last owner said the motor was rebuilt 30k miles ago, If it's the head gasket, Then i guess i was ripped off, paid $3000

Could do an oil change and run it gently and see if it gets nasty again.
Also is the oil over full? That would be a sign of coolant in the oil as well.
But if you had white smoke exhaust that is a sign of coolant in the combustion chanmber, head gasket failure aslo likley for that.

nevermind

You can get lots of odd problems with a car sitting 5 years. Clean it up and see what it's doing now.....you might get lucky.

What year car and motor. Dukes are much easier to change a head gasket. V6 more work. I just changed one on my son's 84. Pretty easy. 84's all had the duke. Add some info as far as the never mind response. We may be able to help.
