My engine does seep a little from one place or another, but really does not leak. I wipe it down underneath with a rag from time to time. I credit the use of red silicone on all cover/gasket interfaces I have done R&R on. Overall, as my third air-cooled experience over all time, this engine has been pretty good. As delivered, the rear main seal spun out some oil. IIRC, I replaced that with two new ones, back to back, and things are good now. And have been for some time.
