When lifters leak down, sometimes it can take 30 minutes for them all to get pumped back up. Sounds like you're just dying to change something, so go ahead. And 3/8 of a turn? Where in HECK did you come up with that?
Rusty, I'm certainly not trying to get you upset. all the help here said 1/4 to 3/4 turn, so I went light with 3/8 in case I wasn't feeling the 'drag' correctly, just trying to be cautious.
