I have a c15 twin turbo nxs engine. Trying to to an over head adjustment on
just need some spec to do the job. I did the valve lash and I need the spec for
The cat engine brake intake and exhaust or are they the same lash? Also torque spec
On eng brake lock nut intake and exhaust are different sizes.
I have the injector height tool just do not know the set order or do I need to use a different
Flywheel pin hole than the valves to set the injectors?
Injector torque spec?

West coast thanks for the specs do you have the compression brake spec for
A cat brand brake not jake or pac, it has a slave piston on both exhaust and intake.
I believe it is called an eco4.
