So I was out fiddling with the truck this afternoon and looked under the oil fill cap, and found this:




Now I've never seen a blown head gasket before, but I have heard oil after it described as "baby ****". Is that what I have here?

If so, how much am I looking at to have it replaced?

Normal in the winter time when the cold air causes water to form on the cap after the engine cools down. When you pull the dipstick is the oil normal or milky if milky the that is water in the oil if normal then no worries.

That's most likely just condensation as that's where is accumulates.
Unless when you drain your oil it's obvious.
Drain your oil and spin it in a centrifuge to see if there's any water/coolant in the oil.

Watch your coolant and oil closely if you suspect head gasket. White under cap is normal (Mine looks exactly like yours right now).

PS...searching would have been quicker as it's been covered numerous times.

Or send it in for a UOA to see if there are any indicators of coolant. Looks like a little more than normal condensation, but with a lot of short trips/old pcv it can be normal.

I checked the dipstick, and other than being a bit dirty (Oil change planned for this weekend) it was fine, no trace of anything but oil.

As far as I know, the pcv has never been replaced, and at this point most of my driving is less than 5 miles, so I would say thats probably it.
