    Got an Idea..........

    I am sure it's a major problem and expense? I will give you $800 for the bike and I will try to fix it....

    Honestly I don't know but I am sure someone will help...at least you got something to fall back on.....

      Mine leaks there too and I rebuilt the engine and just put a new valve cover gasket on. If you get it figured out, let me know. I just wipe it off after a couple of rides and forget it about it. Too many other things to worry about.

        Cromwell,

        I'm not sure exactly where your leak is but it sounds similar to one I had some years ago on my '83 1100E. Take a look at the parts diagram below, items 14 and 17. Item 17 is an o-ring that had gotten hard and caused a similar symptom to what you are describing. If your leak is coming from around item 14 there's a good chance the o-ring will fix it..........and it's only $2.49 from BikeBandit.



        Good luck,
        Joe

                Dave,

                That's just how mine looked. It was right after removing and replacing the head and I thought it was a head gasket leak. Try cleaning the area up and watch closely for the leak. There are passages on either side of the cam chain housing that will let oil from the o-ring mentioned above run down onto the bolt you're referring to.

                Thanks,
                Joe

                    It's just a funky nut (or bolt but I believe it has female threads) that helps hold the head on. The o-ring (item #17) slides onto #14 and seals a passage in the head. I can't see how item #14 would need to be replaced unless it got really chewed up somehow.

                    Thanks,

                        Interestingly, I went out and checked mine and noticed some oil residue in the exact same spot. Not sure it's enough to worry about right now, but something I'm going to keep an eye on.

                          You didn't say whether you pulled the valve cover and adjusted the valves too and replaced the valve cover gasket?
                          The '83 1100ES I recently had was leaking oil between #2 and #3 cyl between the exhaust and down lower around the head gasket.
                          I pulled the valve cover to find a split in the valve cover gasket about smack in the middle as you look down and because the way the head is shaped the oil dripped down and out the opening to the front making it look like it was coming from the front of the engine.
                          Long story short I adjusted the valves and carefully replaced the gasket with a genuine dealer one for about the same price($20) if you factor in shipping as the cheap ones online.
                          Judging by the way it was split, I'm guessing either the PO had not carefully lined it up, thereby stretching it(breaking it?) or it was just a cheap quality aftermarket gasket.
                          Before people get defensive about non-dealer gaskets, I have one of those that I put on my 1100G 2 years ago and have no problems with leaking.
                          Maybe it's more bout being careful lining the gasket up and I put a light coat of grease on both sides to keep it in place as I line up all the bolts before tightening anything.

                            I had the same oil leak in that area. I found that the area where the breather hose connects to the top of the airbox was completely plugged with rust which prevented the engine from breathing. After fixing that problem, no oil leak, Ted

                              Joe nardy, I hope your right, i really dont want to replace the head gasket, do you know, if that o-ring gasket can be replaced without taking the top 1/3 off, thanks for the helpful diagram. Pic below, it looks like it might be that o-ring
