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

Before backing off the valve clearance adjusters, checked the
current valve clearance.
They were all over the place and #1 exh side were out of the spec.
Rest of them were at the limit but within the spec.




All four camshafts looked fine under the initial inspection with
extra scratch marking at #3 cyl intake cam robe.
Probably some sort of hard debris trapped in the past.

All of the mid rocker arms were pressed by finger and confirmed that
the primary/secondary ones never moved during the process so
all rocker arms are fine.






CRK/CYL sensor.
As always, the potting melted under the heat and making the area dirty.
It’s going to take extra time removing all these potting on the TB back cover.

The sensor itself works fine even with majority of potting melted away but
as a pre-caution, I prefer replacing it if the potting melted to this level.




The TB tension was not too bad compared to other NSX that I serviced so
probably this was from the previous TB service.




Due to melted potting, no rubber gasket at the TB front cover, etc,
hard to tell whether the tiny marking just outside of the
brown crank oil seal is the seeped oil or not.
Placed tissue paper on top and it was not wet so probably not leaking but
to be on the safe side, will replace it for this engine.
Normally, no need to replace it on our NSX engine.
