Ok, sounds like the Linhai 400 equivalent is compatible then. They have a slightly different cover design with a bulge at the top which is why the gasket doesn't work.
The liquid gasket is a pain. I had the same oil leak that you have because I didn't use the exact recommended liquid gasket. Pulled it all apart and back again to fix it. I think that is why my wires are frayed now and need to replace the stator. Thanks for the response and good luck with the next bug.
