    Weird Problem While Exhaust Brake Is On

    So my truck drives great, It builds boost perfect.

    Problem is, if I am going down the highway and I am in 6th gear with the EB on and let off the gas.

    The EB will engage, but when I hit the gas it wont disengage and will blow back smoke.

    After a few seconds it will return to normal and drive fine. EB works perfect in every gear but 6th.

    What could it be?

    My 08 has been doing the same thing.

    Best I can come up with is that the actuator is sticking.

    Cleaning the turbo may resolve the issue, but is sounds like you have to disassemble the turbo to clean it.

    I'm hoping to stumble across a reasonable cleaning solution like seafoam or similar.

    As for now, I just keep the exhaust brake off.

    Hopefully someone will chime in with a solution.

    Running the EB all the time is one of the best ways to keep the actuator working properly.

    Some have reported good results with doing a few hard interstate pulls to get the veins moving.

    I've done all that, no luck.

    I have even had DODGE to a turbo clean on it.

    That also has had no luck.

    I have decided to just order a S364.5 turbo.
