Broken ring?

White smoke out of oil catch can line and oil fill.

Nothing out of exhaust.

Car had been sitting for a while, started every 3-6 months.

After last drive this happened, changed oil and filter drove it for about 15- 20 minutes still smoking.

They all smoke after sitting. Take it out and spank it like redheaded stepchild.

Does seem a bit excessive. even a sloppy valve guide can pressurize the crankcase. that won't show on a compression test though. do a comp and leakdown test for starters to hopefully eliminate a ring problem.
