Thread: White Smoke?

  1. Top Of Page | #1

    Angry White Smoke?

    I have a 15 RAM 6.7L that smokes white and smells rich.

    I have an MM3 tuner on it.

    If you turn off the number, one injector smoke goes away.

    I put a new injector in, but I still have the same problem.

    Any ideas?

    White Smoke?

    How many miles?

    Have you scanned every injector to see if you have more than one bad?

    Does it run differently power-wise, or does it hesitate to use the exhaust brake?

    Another possibility is low compression on cylinder #1.

    A quick and easy check for this would be to run a “Relative Compression Test” with a lab scope.

    Yes scanned every injector.

    100k miles.

    The idle is rough.

    That's next.

    I would've done it but dropped the compression test tool.

    I am getting a new one, but why would it lose compression on that cylinder?

    Hard to say, could be a valve, rings, cylinder, head, or head gasket.

    Please keep us posted on the compression test results.

    But it doesn't over heat and does no blow by.
