What I was going to do is test my valves and go to Cummins and buy the leak down test for myself that way I know at least to narrow it down to which ones were leaking!(01-05-2017 )joesherrie12 Wrote: [ -> ]Have 871 Cummins might need injector work, gonna check mettering valve and timmng valve today.

Your first question when looking and calling around should be ...
-- "Do you use Cummins Insite?"
-- "Do you have a proper injector leak-down test kit for an ISX 871?" and "How much does it cost to have this test done?". Shops who are clueless will say things like -- "You can't test injectors without sending them off" -- or -- "You have to remove them to have them leak tested". Or some other excuse.

-- I would also Inform them before hand and make them agree that you will require photo or video evidence (or be able to see the results with your own eyes directly) of any failed components or failed tests before the approval of any work or replacement parts can be made. <-- This is what many of the mega-fleet carriers do and require from ALL shops performing repairs. They got sick of being burned by bad mechanics who lie and run the bill up, claiming failed components with no hard evidence.
