What could be a cause of this milky engine oil cap? 2010 Chevy Colbalt I4

Question

So I open the hood and see this cloudy thing, what could it be?

Answer 1

Notice around the bottom of the threads that you can actually see water on the lip where you add oil. And what I can see of the inside the engine looks like a oil change or two may have been missed. I am assuming this by the burnt oil inside the fill port. I may be wrong as I have little hands on experience with this engine. Adding your year make and model would allow me Google into your engine to see any really common issues.

In the title I put 2010 Chevy Cobalt I4, its the 2.2L sedan. I just changed the oil, so hopefully I see some changes. I wouldn't be surprised if it missed a couple oil changes. Thanks for the info

Haha I totally missed your title. My bad. How long do you run your oil changes?

Truth be told, I have no idea. No sticker was left on the inside of the window, so it could have been a long time since. I work for a small dealership and using this forum helps out when I need to brainstorm ideas as to what may be going on. Since the company left the vehicle on the lot for a while it could've been months since its last change. Filter looked real nasty and the oil looked like my toilet bowl after a meal at taco bell. But she's running good now, lol

Yeah. It's been short tripped and not changed. I would change again withing a few thousands miles. If you continue to short trip I would change at 3k miles or less.

Check the dipstick. If it looks fine, then it's not a head gasket issue. This is normal condensation.
