[QUOTE="kleake, post: 1505675, member: 25987"] Alright guys, I got it back together far enough to fire it up, but as I cranked it, 1 cyl did not have compression. Yea,,, back to that game again. I found cyl #1 is the culprit, so I pulled that valve cover and found the exhaust valve is just a teeny bit open and does not seal. Back the rockers off just a 1/4 turn or so and all is good. I've stopped the motor with the cam holding that valve open trying to get the lifter to bleed down but it's just not working. How long should it take for a lifter to bleed down while under pressure? How can I force it to bleed down? What's the best way to check it? I'm a bit frustrated because I ran into this exact issue when I did head gaskets in the other thread, but that was resolved with the correct push rods for the new rockers. [/QUOTE]
