Hmm, maybe check the breather hoses to make sure they
are not clogged.  Other than that, do a compression
check to see if anything is out of wack.  I'd expect
~150 psi. on that motor?  (somebody with one could
tell you better)  I doubt it's valve seals, they
usually are smoky on decell and startup. Your probably
looking at rings, or hopefully it's just a clogged
breather, which can cause oil to go into bad places.
