Just when you thought it was safe to go to the parts counter

The tappets in the 6.4, 6.0. 7.3, and 6.9 are the same as Olds diesel 5.7 and GM 6.2 and 6.5 diesel.

 

Component sourcing and bidding makes for some damned strange bedfellows.

 

This is according to part catalog from Sealed Power/Federal Mogul. They could be the OEM supplier of the tappets for all we know. Those kind of things in an engine are like roller bearings, you come up with an engineering spec and find an exisiting component that meets or exceeds it and then spec the place it fits.

 

Damn! they could have grabbed some from a big block Chevy or a VW and I'd feel better.

Holy shit, this is a good piece of information to know.
