I have a 2 piece distributor shaft. Does the lower shaft just lift out or do you have to take the valve cover off to get the shaft out. I have a clicking noise that sounds like it is coming from around the bottom there so i think it might be the distributor. I'm just a novice so not sure what different noises would be but took my stephoscope and it was loudest there. I also shorted out each cylinder to see if the noise stopped and it didn't. Like maybe the valves would be the problem. I remember seeing a post a while back saying to short out to see if noises stop. The noise doesn't sound bad but I'm sure it's not supposed to be there even for a newbie like me. Thanks guys.
