OK, indulge me and forgive me if this isn't posted properly. I looked at an 05 today and noticed some oil accumulation in the exhaust tips. The dealer has had the car since the beginning of the year and it only gets started once a week unless it's being test driven. I noticed a little smoke at idle but the car wasn't up to operating temp. Normally this sounds like valve seats/seals but I don't know if it is an engine starting to go south or just the result of sitting for long periods. There were no unusual engine noises. I did a search but didn't find anything. Anyone care to make a guess?
