In my 2006 Dodge Charger RT (126k miles), I noticed yesterday that there was a slight buildup under the oil cap. I did an oil change approximately 600 miles ago. I change the oil with synthetic 5W-20 every ~6k miles. The engine sounds great and I thought it was working excellently.
I checked my oil level yesterday. I noticed under the oil cap that there was a slight white-ish color residue on the inside of the cap. I never noticed this before. It easily wiped away with a bit of paper towel. I have never noticed it before, though I cannot recall ever specifically looking before today.
I drove the care for about 40 minutes today and checked under the cap later. It's as clean as when I wiped it yesterday.
How clean should the cap be? Does any white-ish schmutz at all mean that I've got a coolant leak?
