    Oil from cam ends

    Sorry if the title is 'off', i'm still learning all the parts.

    The bike came without the nice chrome cam end-covers. so it has helped me see this problem. My guess is that the half-circle plugs are worn or something along those lines. The gasket itself seems OK.

    You can see the oil pooling in the seam there.

    Thoughts?

    You were planning on adjusting the valves and replacing those anyway, right?
    Yes, it is clearly leaking.
    Don't forget to apply a thin film of sealant on the new ones and at the top two points where they fit flat against the cylinder head.
    Ultra Black Permatex is recommended by me.

      Eric is correct, and I would also like to add that you should replace the valve cover gasket with an OEM gasket. It appears that the PO used some sort of sealant on it. Those gaskets were designed to be installed dry. Be prepared to remove all that sealant when you do it.

        As KK said. And be extremely careful getting all of those bits of old gasket off.
        Try like heck not to get them into the engine.
        Some people place paper towels or rags in and around the cams.
        Shop Vac might also work in getting the bits out too.
        Also the best time to change the oil and filter.

          carefully remove the sealant and dont dig gouges into the machined head surface or the cover surface. Also stuff a rag in the center tunnel the cam chain goes thru to stop any pieces from falling down into the engine. Anything that falls on top of the cams or buckets can be sucked off with a shop vac when your done removing the gasket stuff. Or blown out with an air hose.

              OK so valve cover gasket and new plugs at the minimum, making adjustments to the valves if needed (probably). Any thing else I should do/look at while in there? I'm assuming this will all have to be done with the engine out, yes?

                  Take off the breather cover..smaller one on top of the valve cover. Take off the valve cover. It will be tight but it will slide out. Rag in the cam chain tunnel. Remove as much gasket by hand and use a utiity knife blade to go around and remove the stuck on places. Do the valve adjustments. Clean all the mating surfaces with a rag and some rubbing alcohol or whatever oil cutting wipe you wish. Do the sealer in the half moon areas as stated earlier. New gasket and wiggle the valve cover back in. then do the breather cover. Pretty straight forward process.

                    NO, the engine does not need to be removed to remove the valve cover...

                    Remove the tank, unplug the spark plug wires, might have to remove the horn(s) too, but the cover will come off with, usually slides off to the left side easier, after raising it up to clear the cam chain.

                    Z1 sells aftermarket cam end plugs that work nicely, but as other have said, use a light coating of sealant on the radius to seal them into that half-moon cut-out.

                    http://www.z1enterprises.com/Cam-End-Plugs--Black-4-GS1100-GSX1100-GS850-GSX400-2086.aspx

                    After you scrape off the old valve cover gasket, use an OEM one, but appy a thin layer of light grease on the aluminum head surface, and on the valve cover side too - this will facilitate a clean & easy removal of the valve cover in the future. If you are careful, you can re-use the valve cover gasket several times without leaks.

                    Good luck,

                    Mike

                        This should be helpful - different bike, but essentially the same process.

                            Most of the time those rubber half moon pieces can be reused after cleaning them. The sealer should only be used on the curved portion of the half moon, you shouldn't need any on the flat portion that contacts the gasket. If the half moon sits down below a level surface where the gasket contacts, then the half moons should be replaced.

                              And I turn the lip around so it is toward the cams..kinda help it from squishing out when ya tighten everything down..look up the bolt torque specs as well.
