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

For some reason, the Eng GND cable was not connected and tucked away behind
the coolant header tank.





The coolant level was fine but the header tank was really old and already turned
into yellow colour.
Will be replaced with a new one any way.




This is the engine bay cooling fan.
I have never seen it operating even under the hot summer in Japan.

In fact, on the later spec MT models, it was completely removed so normally,
we just remove it during the engine refresh service.
Will check with the owner on what he wants to do with it.



As reported to the owner through the Health Check report long time ago, the drain
plug at the bottom of the radiator was still leaking.
The O-ring will be replaced any way during this refresh service.




As seen on many NSX, the hose band at the lower radiator hose was heavily corroded.
Will be replaced any way.




So much oil was seeping from the front and rear cam caps and valve covers area.
While planning this service with the owner, I asked him about the possibility of taking
the engine out even just for the Engine Refresh Stage 1 TB/WP/Valve clearance service.

Looking at these oil seepage, I think it would be quicker and better than trying to wash
the engine while it is inside the engine bay.




However, not looking forward to bleeding the brake while dealing with these bleeder screws.
Heavily corroded and even painted.....




The inner joint of right drive shaft was splashing the grease.





One of the fixing bolt at the rear IG coil cover was in different colour and bit short.


I think I'm going to have fun with this NSX.....
