[QUOTE="kleake, post: 1524057, member: 25987"] Got a few thousand miles on the full rebuild and starting to hear 1 cyl with low compression. As you crank it to start, if it hits that cyl you can hear an obvious low compression. When idling, it sounds like just a weak cyl, but while driving it all runs fine and you don't feel or hear any miss. I'm wondering if I have a valve that isn't seating all the way. Usually as things wear in, things get better, but this is definitely getting worse. Any quick things I should look at before assuming a valve issue and removal of the heads is in the cards again? I'm really getting tired of pulling the heads, this will make the 4th time in about 2 years if I have to do it. [/QUOTE]
