Check the PCV system, make sure there is a good vacuum supply to the valve and the fresh air tube and filter is clean for the PCV system. Remember these motors are low RPM torque motors, so keep the RPM's down. I never turned mine any faster than 3000 RPM. If it still kicks out oil after you have checked everything out then chances are high that the rings are worn out.

You shouldn't have a breather cap. There should be a tube going from the valve cover to the air cleaner assembly with a crankcase ventilation filter on the inside of the air cleaner assembly. HTH. -Jim

It's called blow-by

Could be. Or it could be caused by a clogged or misrouted PCV (Positive Crankcase Ventilation) system. I used to get oil (blow by) in the air cleaner assembly of my '70 Catalina. But at 42 years old and nearly 200,000 miles I considered it normal. HTH. -Jim
