Whiteish slime

[Budguzler]

Poking around today, I noticed this slime in the overflow tank and some in the filler neck. Any ideas wtf it's from ? Will be stopping by the stealership to see what they have to say but I'm assuming this ain't normal. Btw its a 2010 6.2 with 22K miles .

motor oil?

Hmm,didn't know it was piped to the rad. But it's super clean and at proper level.

It is not supposed to be. Motor oil in coolant is a sure sign of something broken / cracked inside of the engine (oil cooler at the filter, block or a cylinder head).

Are you the original owner? Could be stop leak build up if someone put a lot in.

If it is a head gasket, there are a few other ways you can try to figure out it.
1) look at your oil cap, does it have condensation in it? If so, could be blown.
2) white colored exhaust when it's running.

I am going to offer a thin thread of hope. You have less mileage than I do, so that makes me wonder, is your Raptor driven enough? Lots of start it up, and only drive one or two miles wont allow the engine to reach operating temp & "boil off" any condensation in the engine oil. if this is the case, do a oil change, flush out the reservoir tank, wipe out the rad neck and make a point of allowing the engine to reach full temp, even of that involves just driving around.

Yeah that's really not good.... The dealer might want to check your oil cooler to see if its leaking. I know mine leaked because I had to replace it when my truck had only a few thousand miles and the oil and coolant started to mix.

OK I know my truck has this as well and I noticed in my security camera the mechanic cleaning the sides of the reservoir while he was doing a trans flush.
I figured it was just maybe the coolant had bubbled and left a residue on the sides.
No?
