I never thought much of it until I realized that the valve cover on this truck has three small slits that vent it. Never noticed them before because they point aft. This valve cover (on the 216 motor) isn't one with the vent/oil add pipe that sticks up from the cover. So....does anyone know what the original configuration was? The cowl drain ends right over one of the three vent slits. Bummer. Thanks. | | |

I was thinking about this the other day , I think I will extend the drain with a tube down to the bell housing area , or somewhere near there . | | |

Does your vent gasket seal when the vent is closed?
Maybe a short-term and partial solution is to direct the drainage tube to the other side of the block (the intake/exhaust manifold side). I thought that this is how it was supposed to be directed.
Next, connect an extension tube, long enough to reach the bottom of the block.
I have never had this problem with my trucks - just lucky, I guess. My drainage tubes are pointing to 4 o'clock (when looking from the front of the truck).
