I have a 1950 Willy's Jeepster with the F-134 engine. Last time I started it up oil started leaking out of the crankshaft ventilator. Any ideas why this happened? It made a mess!

Does your jeepster have a PCV Valve or just a road draft tube?


Item S is the PCV valve. This illustration is for the military jeep so you won't have the valve assembly shown as item L.


This illustration is of a WWII L134 but the F134 road draft tube (item 28) is the same.

it has the road shaft tube

Oil dripping from the road draft tube is indicative of either extreme blowby (worn rings) or a plugged vent system or heavy foaming of the oil usually caused by adding oil above the full mark.
