I looked up a compression test but it says I need a compression tester. I dont own one of those. When I took it to the shop the guy said he did a compression test and also said it was fine and that no valves were bent up too bad. Also I was pretty sure the squeaking sound was coming from the alt. belt but does anyone know about the knocking sound. It dosnt sound like it coming from the bottom end, it sounds like its coming from the cam gear area or somewhere near there. If anyone has any good advice feel free to call me because Im going crazy here!! 813 334-4028 - Alex
