FAQ
Will this fit my 1994–1998 12-valve?
This listing targets 1989–1993 (VE-pump) applications. Some later 12-valve setups differ—please verify by ESN or OE part number before ordering.
Do I need sealant with this gasket?
Use RTV only where the Cummins procedure specifies (typically at case joints and corners). Do not coat the entire gasket unless directed by the service manual.
What else should I replace while I’m in there?
Front crank seal, any brittle hoses, and worn front cover hardware. Inspect the wear surface; add a sleeve if grooved.
