TUBE CRANKCASE VENTILATOR VALVE
Crankcase Breather Tube - Valve Cover
Steel tube for crankcase ventilation
Steel breather tube connecting the valve cover to the crankcase ventilation system of the L-134 engine. This tube forms part of the early PCV system (Positive Crankcase Ventilation) and ensures the evacuation of crankcase gases to the inlet manifold where they are burnt.

Features
- Steel construction for durability
- Part of the PCV ventilation system
- Connects valve cover to crankcase ventilation
- Prevents excess pressure in the crankcase
- Essential for correct engine ventilation
★ Replica manufactured to original specifications for the crankcase ventilation system of the L-134 engine.
Installation notes
The tube is installed between the valve cover and the PCV system. Ensure a good seal on both sides to prevent air leaks. Check that all connections and hoses of the ventilation system are clean and free from blockages for optimal operation.
Compatibility
This tube is specific to vehicles with the L-134 engine with gear-driven camshaft. Not compatible with early MB/GPW engines that have a chain-driven camshaft. Different variants of the PCV system were used - early systems ventilate via the side valve cover, later ones via the top of the valve cover.
Historical context
Willys was one of the first manufacturers to use a closed crankcase ventilation system, where crankcase gases were not released to the atmosphere but directed to the inlet manifold to be burnt. This system was particularly important for military applications where jeeps had to drive through deep water.
