I only said I was going to do them all if it fixed the one I know is screwed up because if it doesn't fix that one, I'm going to toss and replace them all. And this time I'll take them all apart for a cleaning before installing them.
I suspect there is more than one with the same problem. I could've pointed them out when I was running the valves because they would bleed down and I'd have to prime it to pump them back up.
Inexperience bit me here, but thankfully I was thorough on other things so the cam/lifters survived break in.
