Crazy right? Well Buzz said earlier to pull the wires one at a time to see if I could isolate the sound. reading more on it seems a lot of people use that method to detect worn rod bearings as the knock sound stops when the wire is removed on the noisy cylinder. Mine however, is doing the exact opposite and the noise gets much louder when I pull the wire on cylinder one. I just don't know what else it could be other than a slipped sleeve?

It sure sounds bad compared to mine. Im starting to think I do have a bad lifter. Yours is more of a knock than a tick. Im gonna have to try that method out and see what happens.
