    OIL Leak

    I recently developed a leak on the shifter side of the bike. I just changed the cam cover o-ring, the valve cover o-ring and they are not leaking. The oil appears to be coming out of the long head bolt near the front of the engine. It looks like it is seeping out the top. The oil is going down covering the front left corner of the engine and the starter. I put all new gaskets at 42,000 miles, including a new head gasket. I am leaning towards a possible loosen and retorque the head as a fix. Any other ideas about a hidden o-ring or anything?

    Picture?

    Me think Ken has identified the source and a re-torqueing of head bolts just might solve the leak.

    Oil goes up the right rear head bolt to lube the camshaft etc. on top of the head. I am not sure what oil would be doing in the left front head bolt but then re torquing is such a simple quick task I say go for it and see if it solves your problem.

    Thanks. It looks like retorquing is my plan. I didn't have time for pics today. I had some family in so I have been out visiting. I took another bike for the day. The TW just made a quick trip to the store. I cleaned the engine the other day to try and find the leak so pics won't show the leak other than the location. I'll try for a couple of pics tomorow.

    I've found the head bolts like a re-torque a few hundred miles after re-assembly of the top end. I initially torqued them with a digital wrench and maybe 200 miles later they all took another 1/2 turn or so to get back to the spec torque.
