I installed a pcv valve which helps immeasurably.

First, I Installed a PCV valve in a hose from the 2nd opening in the top of the rear intake manifold to the top of the valve cover T and created a negative pressure in the engine and crankcase thereby reduced the oil leaking into the bell housing, but not before coating the clutch disk. As a result, I have slippage at high-speed shifting.  2 weeks ago, I have installed the pan you have mentioned and the 1/8 copper line to the intake manifold. That has helped to keep most of the oil from dripping on the floor of my garage.  I am watching the color of my spark plugs to see if there is any problem fouling the last 3 plugs with oil.  So far so good.  I can now drive farther than
