My 20 valve did it awsomely on the track! on corners leaving large clouds of smoke right on apex.
Reson? i had far too much oil in the sump, and pulling huge deacceleration revs. Blue smoke when got back on gas.
Cure? drain oil, (needed changing) fill to correct level and clean plenum of lake of oil sitting on the bottom of it. Its a task that is quite frequently needed as oil likes to collect in the plenum. Judging by oil markings on intake pipe id say its from the rocker cover breather that plumbs into the side of it.
Internal wind created by 4 pistons moving at 8000+ is pritty ferce...
