It's ok, David, I speak "haz" by now. <img src="/forums/images/graemlins/smile.gif" alt="" />

I'd try the rednek pressure test. Seal a hose to the plug hole and blow in it. You will get the minor leakage past the ring gaps, but a bent valve will show up pretty easy. I'd also do the visual and maybe a ruler test on the valve height as David says. A bent valve will show up as shorter.

David is pretty good at this, once you learn to read his prose.

My fingers are crossed for you.
