I would like to thank you guys after reading this thread, I used a piece of 1/16"steal cable chuck in my 3/8 cordless drill and ran it down through the oil returns on each head while still on the motor, Then air up the cyl and pop the valve springs and all of the oil seals were either gone from age which I found most of them ( rotten rubber) just under the valve in the oil return valley on the head and used my trusty shop vac suck the shit up and replaced them, put new valve cover gaskets on. Fired it up ran it for about 15 minutes and wala no more smoke then change the oil and filter. the perfect ending to possible mess...
