This is common with high mileage engines, or any engine with worn oil
control rings.  The Gunk treatment cleaned out the gunk that was helping
the worn oil rings to seal.  The oil in a flat four like ours drains
down overnight and gets on the cylinder walls.  Worn oil control rings
don't sweep it off well, so it burns off, leaving a blue haze.  The more
gas you give it the more you burn, hence more smoke.  Fortunately, they
work better as they warm up and expand.

BTW, smoke on acceleration indicates worn rings, smoke on deceleration
indicates worn valve guides.

Not much to be done, you can try some "no smoke" oil additives if you
want.  Time to start saving for a rebuild, I have the same problem!
