have you found that oil lk yet? I would suspect O=Ring leakage in cyl hd cover. get some directions and you're going to need the camshaft(s) lock tool. I made one. About forty bolts holding it down.

Yes, I broke two of the cyl hd bolts. Getting ready to drill them out and want to be prepared with the tap. Specs pls ! Also, looked at the posted description of the timimg tool for holding the cams (mainly dimensions). Any dwgs available ?
