Hey guys i have a problem and was wondering if you could let me know what was going on with my motor. About 2 months ago when i did my first oil change i took the oil filler cap off and noticed a foul smelling yellowish white residue that was all in the oil intake tube. I wiped it all out and went on with the oil change thinking it may have been just bad oil or something from before. Well about 2 weeks ago i went to do a basic checkup on the truck and it was there again, i will post pictures of it and maybe y'all can let me know what might be causing it or whats going on.
