Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Although we are not going to adjust the window glass alignment on this occasion, the driver side door glass won’t go fully up with the door shut.
Tiny gap was observed around the edge of the glass.




Nothing unusual and just showing the presence of moisture inside the engine in the form of blowby gas.
You can see them at the back of oil filler cap.

If you park your NSX for prolonged period like a few months, slowly at the cam lobe, journal, main metal, rod metal, etc will loose their oil film and with big temperature difference between day and night, eventually, these moisture will cause condensation at the metal surface.

Next time when you crank the engine using the starter without any pre-treatment first, it will scratch the metal.
It won't cause issue immediately but if you repeat this many times, it will make the scuff marking worse and worse over many years and one day, without any sign of failure, your engine will fail.

Another reason to drive your NSX regularly.






I have noticed this several years ago on this NSX but our little friend loves chewing on these parts.
