David, since rebuilding the engine, mine is pretty near oil tight, but with a similar leak to the one you mention. I have used a silicone valve chest cover gasket but after a run there is always a bit of oil on the bottom right hand corner of the cover. I suspect it is oil mist coming out of the vent holes being blown rearwards by the 4 blade fan, or possibly a poor seal on one of the hold down screws. I have decided that it is less hassle to just give it a wipe down after a run rather than take it apart to try and cure it.
