My SD started making a funny knocking sound yesterday. It reminds me of loose valves a little but not quite. Also it is loud enough that I didn't want to just keep driving it. It is kind of like a double tap one louder than the other once or so a revolution.
So I pulled off the VC checked all the valves and all are good. I also thought it might be the chain stating to come apart but it looks fine also. With the cam marks lined up it reads ~3.5deg. at the crank. However I got it to recreate the sound while manually turning it over. It is coming from the area of the vaccume pump and IP. As I slowly rotate the motor it makes a creaking(something being conmpressed?) sound for about 20 degreees of rotation and then a light knock followed by a louder knock within another 5 degrees of rotation. It seemed to do it at least 2X per revolution. I'm a little worried and wont drive it until I have it fixed. Any help will be greatly appreciated! Thanks, Stephen
