<VV> Oil fouled plugs

I do think replacing the valve stem seals on the intake valves is a quick and 
inexpensive way to see if that is the problem.

I rebuilt the engine on my 140, 67 cpe. engine 7,000 miles ago (October 2010) 
but, some months ago, started fouling plugs with oil.It happened on the left 
bank only. Must of the time it is the #3 and sometimes #1 or #5. It just 
happened on city driving or at first start on morning.While on the road, even on 
500 miles trips, it runs fine without any trouble and minimal if no oil 
consumption.Suspecting on broken rings, today checked compression and it is 120 
psi. on all cylinders.
What could be happened ? Broken oil rings only ? Worn valve stem seals ?
It looks weird to me but maybe some of you wizards could lead me on the right 
path.
