Thanks for the replies! Its hard to tell if the guides are bad or not. I looked down into the engine with a scope, and from what I can see, they look a little worn but its hard to get a good view with the chain in the way. I am going to pull the chain out so I can get a closer look at the guides. Chain is definately bad, as my tensioner is about 1 "click" away from being fully extended. I hate to have to tear the engine down, due to the fact that it seems to run strong, and has 125 psi compression. Has some serious top end chatter after it warms up, even after checking the valve lash.
