OK guys - I got the Napa Viton seals in on cyl's 1 & 6 without too much trouble. The old O rings were hard and probaly a few are/were cracked.

My question is this: Should the O ring stay in the second groove on the valve (closest to the head) when the springs go back on. I can't get mine to stay there. Any time I try and compress the spring (or even when it's already compressed with one of those tools) the "cap" pushes it out. I can't figure out how to get it in there without mashing it in after compressing the springs...? Is there a trick to it or is it ok for it end up where it ends up?
