    I'll pack it up.
    Regarding the step vs. straight stem.... I just did some research, and the newer version is the stepped piston shaft (yours), but the consensus on another forum was that it isn't a big deal as long as you maintain your gear. Short version, SP had some instances of the straight stem piston digging into the old style flat HP seat and getting stuck. The step is meant to limit travel, but the newer concave seats obviate the issue... as does periodic (annual-ish) checking of the HP seat.

    Respectfully,

    James

    There's a saying in my line of work.... If you make it idiot proof, we'll make a better idiot! Looks like the better idiot got to your MK5 at some point long ago, lol.

    @Open Ocean Diver
    Please consider sending your piston to @rsingler . I'm sure the Mad Kind Doctor would love to operate on it and give us another fine primer.

    You could probably get that nick out, the piston would be a bit shorter meaning IP would be a bit higher. The idea of grabbing a piston from another MK5 or 7 is a good one. I have a MK7 around somewhere I have never opened up. It's in a box somewhere (I recently moved) but if you get stuck, let me know.
