I took off my oil fill tube a few days ago to put in some Seafoam to clean out my engine and when I took it off I notice a bright yellow gel built up around the top part of the oil fill tube. I continued to drive until the next day when I changed my oil, I was kinda worried still about coolant in my oil but there wasn't any. My coolant level never dropped and I've never seen any "chocolate milk" oil in my car.

It only happens on the very top of the oil fill cap, not the actual tube. It has never went below that level and it burns away when the car gets up to temp. Does anybody know what this yellow gel could be?

If it is just a little, when the engine is cold, it could be normal condensation. However, if you haven't done you upper and lower intakes, you may want to put that on the list of things to do. At your mileage, you could be on borrowed time.

I noticed a little bit of this stuff in the fill tube about 6 months-ish before I had to have my intake gaskets fixed. I think it was a sign that it was on their way out... Hopefully your'* is just from a bit of water that got in somehow.... Good luck, and just keep an eye on your coolant level.

Here'* the link from when mine failed:

Hope this helps!

Yeah, it'* only a little and it only happens when the car is warming up in cold weather. If the car is warmed up then it goes away. My coolant level hasn't went down at all since I did a Prestone swap in January, and the last owner had the intakes done before me in 04. He had the uppers and lowers replaced along with the Manifold.

It sounds like normal condensation, at this point. I'm not sure when the aluminum framed LIM gasket was introduced, but do you know if that was used? It should have a silver or gray color, instead of the black of the plastic gaskets.
