Not sure if i've been sleeping during my oil changes, but i really don't think i've ever noticed this before. It really reminded be of mustard! it was almost the same consistency too, it we more of a jelly-ish consistency. Has anyone ever seen something like this? and what's wrong? when i drained the oil it looked the normal color and consistency. here's the images

here is in the engine bay where the cap screws into.

Condensation build up combined with blow by results in that emulsion. which is normal in colder weather. Longer drives which allow the oil to reach operating temperature for an extended period of time will help prevent this. It's nothing to worry about. Hope you didn't drain oil too early.

(major sigh of relief). I thought a gasket was going. This truck has taught me a ton. I never new that happened, and fits inline with recent events. The weather started to get colder over here, and i've been going to the train station that is close by and have been in a rush and haven't been letting the truck get to running temp fearing that i would miss my train. I'll be sure to let it warm up now.
thanks for clearing that up for me
