    Engine Oil Leak Questions

    My 80 1100ET has what seams to be a serious oil leak. I am fairly sure that it is leaking between the head and the cylinder. I have re-torqued everything but it continues to leak. I believe that with my limited knowledge of motorcycles I scratched or gouged the head or the Cylinder or both while trying to remove a difficult gasket. My questions are:

    1. Is there something I can add to the gaskets to correct this problem?
    2. Would it be better to take it to the shop and have the bad areas
    resurfaced?
    3. I assume I will need new gaskets to correct the differences of the shop
    work. If so where do you purchase them.

    Any assistance or advice would be greatly appreciated. Learning to work on a motorcycle by trial and error has been very expensive!!!!!!!!!!

    You need to disassemble, CLEAN, possibly do a resurface on the head & cylinder, install new head gasket, AND change the base gasket also so it doesn't leak after you put it back together. Ray.

      Just a thought, but I was running those open top head nuts for a while. if you don't put a little bit of sealer in the top of the nut oil will leak down the threads like a mother. Not sure what your setup is, but I thought I would throw it out there.

      Oh and after I blew out a stock paper base gasket I switched to a rubber coated metal gasket for the base. Cometic makes them for me. I get 0 leaking from the base gasket now. I don't remember what they called it.

        If you just aassembled it and it was not something that has progressed over time. I have cut the O-ring that are used on the two inside head bolts before. Talk about oil going every where.

        If it's leaking this much, what did the cranking pressure come out to for each?

          Also install new 0-rings on #1 & 3 head nut's cause if they leak you'll think it's a head gasket problem.
