Yellow gunk on oil cap in engine bay?

[EWC88]

Changing my oil, have oil drained, I take off the cap in engine compartment so it shoots out the oil faster and I notice on the cap and inside where the cap sits is this yellow gunk, what is this? I stopped everything and haven't finished job because I'm worried. I will get a pic up.

Condensation. Pretty typical for 4.7s that don't see much action on the highway.

AGH

nasty ****.



Pull the baffle out, clean it all out. Then treat the oil with seafoam and you're gonna have to change it again more than likely.

How you get baffle out? Well new cap fix this?

Pull up on the tab in the middle
And no, not a cap. It's purely the design of the 4.7, keep it from properly circulating the oil to mix the water together.
You might also check your PCV valve and make sure it's not obstructed

My first oil change had a yellowish/orange tinge too the cap....I used mobil one and some of this stuff called motorkote, cap looks new after 20,000 miles.

You add it to the oil? If so how much of it?

my durango's 4.7 had that starting. I think for the durangos there was a TSB for that. New filler neck or PCV replacement i think

My 3.7 had that when i first bought it 2 years ago. I cleaned all the crap off of it and its been fine ever since

at 28 bucks a quart, not very much!...seriously, add a few ounces right now......then again when the oil change is due......by the next oil change it will be gone.
