Question about Jake brakes on a cm2250

[Rawze]

First and foremost.. is this truck de-mandated (deleted)?. If so then having the programming reviewed to ensure it is safe for the engine etc., is priority #1.


next, Will the engine pass a rail leak-down test as shown in this video?...

* Has anyone bothered to ensure there are no intake, CAC, or other boost, egr piping, or exhaust manifold leaks?. Maybe use some block-plates on the turbo front and back then pressurize the whole engine up with 10 - 30 psi of shop air and check for any. The allowed leakage rate for the intake system (at 30 psi) is no more than a 10 psi drop in one minute.

* Has anyone checked to ensure the overhead cam has not slipped.

* Also has anyone verified the part# on the head to ensure its part# matches exactly for what is required according to the ser# of the engine?. There are different heads that are required for for different tier engines out there.
