The PCV system needs to be hooked up. If you have both lines blocked off, there's nowhere for the crank case pressure to go. That's why oil is blowing out your dipstick.

The PCV valve in the front of the valve cover needs to be hooked up to vacuum below the carburetor. The vent at the back of the valve cover hooks up to the air cleaner.

Unplug your plugged transmission vent if it is your transmission dipstick tube.

Choke type should have nothing to do with the pcv valve. You need to hook that up to release pressure in the crankcase.

I had this problem up until my engine finally nuked itself on the freeway. Bad PCV plumbing, bad oil, cracked head and worn out piston rings. This was at 180K so there's definitely some life left in your engine. Check your PCV plumbing.
