Oil burn cloud on engine deceleration

I thought I eliminated the smoke! Till I didn’t...

I tightened the intake bolts to 30lbs. Took it out for a run, first time down a hill, NO SMOKE! Second time down a hill, smoke :(

When I get to the bottom of the hill now I give the throttle a bump and it burps/clears the smoke out. Give it another bump and no smoke.

Anyone want to buy a 69 Coronet?
I love 69 Coronets. Pics? Dang, too far away!
