Slightly rough idle after driving with oil leak
Hey guys! I'm starting to run out of money on maintaining my 6.0 and now I have another problem. Once my truck hits operating temperature and is driven for about 20 minutes the idle starts to get a little rough. It's not really bad yet, but I can see it getting worse. To combat this I thought the oil was overfilled, so I changed it. However, when I was under the truck I noticed a lot of oil residue by the oil pan, transmission, and by the starter. I'm thinking I have a slight leak that is causing this problem?? Any suggestions?? You guys have helped me in the past. I wish I was as knowledgeable as you folks.
