Anzir,
In your second post I can see you installed the logo valve caps. I had those as well for about 7 months, and purchased them for a friend when he took delivery of his X100D. My friend was in for service last month and was told he should remove them because they can damage the valve - so he removed them. My initial reaction was that the comment from the service tech was BS. Until it wasn't.
I researched it more and found this:
Replacement air valve caps
I ended up removing mine it wasn't worth the risk. Do I think something might actually happen? Who knows. I didn't want to take a chance.
I figured you should know and you can make your own choice.
Nice mods by the way.
Thanks! I had thought about the additional weight but I didn't think about corrosion. Sounds like I'll be taking these off. Appreciate the heads up!
