★ Replacement gasket for the critical connection between exhaust manifold and exhaust pipe. A fresh gasket prevents exhaust leaks and engine performance loss.
Application
This gasket fits vehicles with L-134 'Go Devil' engine (1941-1953) and F-134 'Hurricane' engine (1950-1971). The categories in which this product appears indicate the exact applications: Willys MB, Ford GPW, M201 (Hotchkiss), CJ-3A, CJ-3B, M38, M38A1.
Installation notes
Replace the gasket every time the exhaust pipe is removed. Ensure both flange surfaces are clean and flat before fitting the new gasket. Tighten the two flange bolts evenly in a cross pattern to achieve uniform sealing. Check for any leaks after a few miles of driving.
Compatibility
Note: this gasket is specific to the 4-cylinder L-134 and F-134 engines. Not suitable for later 6-cylinder engines. The 2-bolt configuration is standard for these engines. Always check the condition of the flange surfaces — a warped flange cannot be compensated for by a new gasket alone.
Historical context
The original part number 634814 was used by both Ford and Willys-Overland for their military jeeps during and after WWII. This flange connection was standard on all four-cylinder jeeps from 1941 until the early 1970s.
