CRAP! I'm smoking!
It's generally agreed upon that If it's burning oil on deceleration its sucking from the valve seals/top end; if on acceleration it's the rings/bottom end.
It was mentioned before, check the intake bolts; I like to use #2 seleant on such devices.
And if you really want to know where the wild goose goes; leak it down.
Curious.... What weight oil are you using? If it's something like 5-30 synthetic, that's too slick.
