Went to change the oil on the Taurus I bought 2 weeks ago and to check out a few other things. I could smell something getting hot once in a while and found oil leaking onto the exhaust/cat on the passenger side. It's not a huge leak but definitely getting oil seaping all the way around and a oil build up on parts. How much of a bear is this to replace? Since I don't have a garage (live in an apt) is this a job for my mechanic? I didn't end up changing the oil as I figured it'd be a waste of good oil with changing the oil pan seal. I don't think a HM oil will help or fix this.
