Re: R51/3 - metallic ticks from one side of the motor
Other than being a mess, could one run the motor with the valve covers off for a few moments, if one concludes the noise is coming from the head?
Also, if your carbs aren't well balanced, one side might sound different from the other as they would be carrying different amounts of the load.
Even though you have a new electronic ignition, I'd still hit the timing mark with a strobe light to make sure it's timed correctly and that you don't have differential timing. From my minimal experience, that will cause the two sides to sound different. Just because it's new doesn't mean it's working correctly.
Forgive me if I'm repeating the suggestions of others.

Re: R51/3 - metallic ticks from one side of the motor
Thank you very much for your time and suggestions.
Did you hear the ticking?
I understand that boxer's do sound different on each side, but I am also trying to understand if you guys hear what I mean?
Can you hear those metallic ticking on the right size? Or is my wife right?
The mechanic's stethoscope is a great idea.

Re: R51/3 - metallic ticks from one side of the motor
Another thought - What if you were to slightly tighten up the valve clearance on the right side to see if there is a difference in the noise? If the noise changes, then you know the culprit. I wouldn't necessarily leave it with tight clearance. I'm just thinking of it as an experiment.

A bent one will "tick" under load. Obviously, check all 4. Replace all the bent ones.
The part number is 11 32 0 033 170----push rod R51/3-R50S.
When I ran Bench Mark Works, we had them in stock. Max BMW has all my stock now.

Replaced 2 just to be on the safe side (they still where ok).
Unfortunately it did not make any change.
Thanks again!

Another cause can be a bent camshaft.
Dont ask me how I know.
