It could be the reed valve. Question becomes what has changed that is allowing oil to gather in the vent area vs drain back into the engine?

Im gonna go ahead and order a new breather reed valve assembly { $30} and install it and see if that stops the oil coming thru the vent tube into the carberator assembly. I only paid $600 for this mower and it really does run good and cut well , so maybe the reed valve will fix the infrequent blue smoke issue.

At least I now know, it is not the valve seals.

I Just remembered that when I bought this, the guy told me that he just did a oil change/ filter change . I checked the oil gauge and it was slightly above full. I was reading some info online, that if to much oil had been put in this engine, it can cause the oil to bubble up and feed into the breather tube- carb assembly. I drained out about 1/2 quart of oil which brought the oil into the proper range on the dipstick.

This simple issue may have been the problem but I wont know until I mow the yard again.
