I have a 99 Diesel. Today I was riding and something happened that sounded like an exhaust leak. When I got it home I found a small machined hole in the cylinder head leaking. The machine lost power from it (could it actually lose any more? LOL!) Near this hole is the decrompressor. Has any one ever had this problem and how did you fix it. I have the service manual but it gives no information on this hole or the decompressor.
