I was doing my oil change and came across this. I had overheating issues and i thought i had fixed it cuz it was running good. But now not sure, doesnt this mean my head gaskets are bad?

Do a compression test,

You have coolant in the crankcase. Compression may or may not be affected.

What good is that??? There is clearly coolant mixing with oil.as stated above your problem is clealy going to be a headgasket.

I assume by the post that the oil looks fine and the cap is the only thing that had that. Also it will look like that on the valve covers.

Yea the cap had it as well as the neck of the valve cover.

So would i need a compression test?

Well I'd pressure test the cooling system if anything. Do you have low coolant ever? is it staying filled? I had that on my oil cap on my 50 and I cleaned it and never came back. its been 2 years. It may be nothing . Clean it off check the condition of your oil day to day. See if this happens again as mine never did it again.

drain the oil..compression test to..i think if the timing cover has a crack in it it can leak coolant into oil..but usually it will be the head gasket

Seen this alot on engines with absolutely no problems at all.Its called...."condensation",...LOL!

The compression may or may not help you.

How I found my leak is by using a leak down tester.

You hook it up like a compression tester thru the spark plug hole. You do the test on each cylinder by popping off the distributor cap and following the firing order. (example: the rotor is pointer to cylinder#1 fire, hook the tool to that cylinder.) Then you hook the air compressor up to the tool and shove air into the cylinder. While the air is going into the cylinder, if the guage shows there is a leak you need to track it down. If found mine by popping off the radiator cap and putting my ear next to the fill hole. I then heard the bubbles coming up. I would check cylinder #1 and #5 first in your case.

Good luck and stay away from that GM orange coolant!!! [Smile]

+1

it's not a sign of a problem, it's an indicator that could mean absolutely nothing, or when combined with other signs could mean a failed gasket.

I had the same thing going on with my car, new trick flow top end with less than 1500 mi and my car would do the same thing but it wouldnt lose any water. I would drive it on short drives for commute and my commute would be like 3 miles so it wouldn't really get the engine hot enough to burn off the condensation, so I would clean the cap and check the next day same thing but if I went on the freeway for a few exits or drive it for like 15-20 mins and check it was gone and that was almost 2 years ago and it still runs strong

I see that a lot on forklifts that don't get driven very often or don't get warmed all the way up. Condensation builds in the valve cover and gets in the oil cap. Do you drive the car all the time or does it sit a lot? I also had this same issue with some tall aluminum valve covers I had, the problem was there on 3 different engines.
