thanks Ed. I was going to put a small line of caulk down the center of the gasket, depending upon how fluid it is, I might brush it a little with a glue brush. Figured I'd do the one side first, apply the gasket, do the other side, then put the cover on. And it's all going to stay right in place while I do all of this. yup...
The good news is that the oil/lube only fills up the bottom 8 or ten inches of the cover so the only place to leak is right at the bottom. I don't even have to do anything special for the top 80%; oil never gets there, chain just runs through a pool of oil at the bottom. Need to get some more 90/140 lube today.
