White condensation Foam in oil cap

[ZZman]

I have a 2002 Buick with a 3800 super charged engine.
I just changed the oil yesterday and noticed for the first time the above mentioned oily foam. Not alot but some. This is a first. I am thinking the fact that it has been extremely cold and the filler neck is very high up from the lifters that it allows this to form.

Your thoughts?

Yes its condensation, I see you too are from MI, short trips or even longer ones where the oil is not getting up to temp is why your seeing this,no concern.

No worry. The filler cap and hole does not tell much positive or negative. If the oil on dipstick looked milky then you have an issue.

It's probably nothing, but this advice is good. It's generally an easy replace, anyhow.
