Valve noise

My em2 has some valve noise @2800 RPM to 5000 RPM. Maybe higher but motor is loud. Full throttle no noise.mostly on deceleration. Just did a valve adjust two times and no difference. Any ideas......

Either you did the valves wrong or it's not valves at all.

Those engines typically seemed to develop a lot of piston slap noise cold, and main bearing rattle hot. Not really a big problem as long as that was all. Most long term owners never noticed it, because it kinda developed really slowly.

But it really could be almost anything. I can't hear a dang thing from where I sit.

Manual trans-- input shaft bearings?
