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

After replacing the Crank Pulley on one NSX yesterday, another owner visited my place in the evening to leave his NSX at my place.


Today, I'm working on it.


The menu is to replace its Crank Pulley, Coolant header tank/cap and the yellow clips at the windshield lower molding.


Long time ago, when I worked on this NSX, I had to remove the widshield lower molding.


At that time, I had limited spare yellow clips and thus, I didn’t like the way it was re-installed.


Two of the Yellow clips were deteriorated and didn’t sit properly.


The parts was ordered and although I had the parts for many months, we just couldn’t come up with convenient timing for both of us and left it until now.








Crank Pulley, before and after.

Your NSX could be similar to what you can see here.

Lots of oil gunk/sand/debris.....

With standard Timing Belt service, the rubber seals at the Timing belt covers were not replaced and quite often, the valve cover gaskets were not installed properly resulting in this kind of oil leakage....

Also, note the corroded two bolts at the TB lower cover.
Please have them replaced at the next TB service.

After talking to the owner, we spoke about having the TB/WP/Valve service this year.

Cleaned it to get this result.
