Unfortunately sourcing parts directly from Cummins has pretty much become impossible, at least where I am. The Cummins Sales & Service locations will not sell parts for a Chrysler 6.7. CPL number, and a lot of the parts are flagged in their system as “not able to sell”. FCA must have signed some sort of recent exclusivity agreement. We used to get a lot of the parts directly from Cummins but that’s no longer the case. There are actually some parts on these engines that are proprietary to the FCA 6.7 Cummins onlyBack in the day I had a 97 12 valve. At certain intervals the tappets required adjustment. Each cylinder had its own tappet cover with an "O ring" seal. The dealer here in canada wanted almost 30 dollars per seal. Since we did a lot of weekend camping in Michigan back then, I stopped at a Detroit Cummins shop on the way home. Price was 3.50 per seal. We Canadians really have to bend over for parts. I understand that there is an exchange rate but parts prices are rediculous here. Short story is get. your parts from Cummins if possible.
