A few weeks ago I changed the oil in my mother-in-law's '05 Volvo S40, at least I think it was an S40. Small car with 5 cylinders. Lest anyone think I'm a complete moron, I knew the model at the time of OC, just not sure of it right now. Anyway, the underside of the oil cap had some goop in it that kind of looked like butterscotch pudding (very light tan color) and was almost the same consistency.
I cleaned the goop out and at first thought it was from an overfill of oil. When I drained the old oil it darn near overflowed my drain pan there was so much oil. But then when I filled it, it took seven qts instead of four or five. So them I'm thinking the goop was not a result of overfill. Now I'm thinking it's from condensation. This '05 is seldom driven (7500 total miles) and when she does drive it's always very short distances.
Am I correct in thinking that the soft goop is a result of condensation? If not, what do you think it's from?
I don't know when the last oil change was before the one I did, but I do know that it had been changed at least once before my change.
Thanks for your input.
