Noticed some sludge while changing the oil today

2015, 112000 miles. Changed to oil today and noticed some white sludge around the cap. It’s running fine. Oil I drained looks dirty and red but not milky. Coolent level looks a bit low, but clear. Should I be worried?

 

Probably no reason to be worried. This can be due to short trips where the engine doesn’t get all the way to temp. Most of my trips are in a city and my cap had the same thing when I first went to change the oil.

As long as you’re taking it out on the highway to get it up to temp for a good while 1x a week or so, you should be fine.

 

That's common during winter time, it's just condensation. If you do a search for "condensation under oil fill cap winter" you'll see tons of instances of it.

 

Normal don't loose sleep.

 

Does your value train look like this? If it’s gummed up you have sludge.
