'05 Grand Cherokee - possible head gasket problem

Wipe that out, and take it for a long drive. About an hour should be good. Does the oil look like that also.

No the oil on the dipstick looks fine, and took a good look at the antifreeze too and it's super clean

I'll probably go ahead and do an oil change next weekend. Since it's last change we did a 2600 mile road trip, with camper in tow, so I'm sure its due.
