Next time you start it up, smell your exhaust. Should be pretty easy to tell if its oil or coolant. Just because your heads are not cracked does not mean they aren't warped. If your exhaust smells like coolant when it first starts up, I would pull the heads and have them checked for cracks and deck flatness at a professional shop.

So just incase what are some tests and stuff I can run. I added a quart of oil and hasn't been over 1000a miles since my last oil change. The coolant is still fine. But I pulled the oil cap off and there was a milky thickish substance on it and looked like condensation on the top? I might as well start at square one and try and figure it out. Also if the heads warped what's the best thing to do? And if its cracked what's the beat way to go? Thanks guys ill check on a bunch only got 2the days off that ls for the help...
