Installation notes
This bolt secures the front of the valve cover and passes through the ventilator baffle. Use moderate tightening torque — over-tightening damages the thread in the aluminium block. Check the cover gasket when replacing.
Compatibility
Specific to L-134 L-head (flathead) Go Devil engines. Not applicable to F-134 Hurricane engines (with overhead valves). Note: this is the front (long) bolt — the rear bolt has different dimensions.
Historical context
The L-134 Go Devil engine was the reliable workhorse of the Willys MB and Ford GPW during WWII. The side-mounted valve cover with integrated crankcase ventilation was characteristic of this L-head (flathead) design from 1941-1953.
