There are still places in engines where zinc is required. Unless you put a roller rocker on the engine, this is one place that needs help from the oil. Even then, a roller rocker only transfers the metal to metal load to a axle pin, but it helps.
I use Synergen products. Their oil additive or oil will eliminate this problem. If it doesn't, there is oil system issue.

As far as coil bind.. I'm definitely not a professional, but when was the last time you pulled out your feeler gauge and saw how thin even 0.100 is? Imagine it at rpm crashing coils while oscillating multiple times per cycle..
