    "C" valve went bad again on my Meyers e47h. This is the second one in about 4 years. They both swelled in the shaft area where it goes into the coil. One was the original Meyers, the other was SAMI part. What is likely causing this. These valves are expensive!!

    Cross over relief valve not working properly.

    They'll swell the C valve even with a perfectly working crossover...the problem is that that "perfectly working" crossover is undersized for the job and always has been. The CO just can't distribute the pressure shock fast enough which causes it to place the force on the C valve. And after enough repeated impacts it swells the C valve stem. One hard hit will swell it and so will 100 light ones over a period of time. It's simply the nature of the beast.

    it's just the way it is! I just wish they weren't so damn expensive!
    there's got to be a modification to help alleviate this type of problem.

    Either not hitting anything, or switching colors is your only viable options I'm afraid.
