Hi,
I just rebuilded my engine and now I get a knocking sound from somewhere in the block at about 2000rpms.while holding the engine at that rpm, I retarded the ignition fully and the knock disapeared!!! Then I pulled off a coil (one at the time) and noticed that cyl # 1 knocks as soon as it gets ignition. So for me it must be piston pin? But before the rebuild the engine was fine, it only burned oil!
Does this have to do with the detonation sensor??
Please help
