High humidity engine break in

Does anyone have any thoughts on high humidity engine break in? I have brand new Superior cylinders on an 0320d2j.
 
Are you asking how to handle break in because you are concerned about corrosion? Or are you asking how humidity affects the break in process?

I’ll answer both: fly it every day until it’s broken in and then change the oil and corrosion won’t be a problem.

Humidity has a negligible effect on engine performance and won’t affect the break in process.
 
Burning Avgas produces water.
After flight, remove oil stick to let the water vapour out of the engine while
engine is hot. This greatly reduces the risk of corrosion.

Good luck
