  1. Potential C32B Engine failure – Intake Valve guide

    by , 09-02-2011 at 05:31 PM (Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer)

    I regularly have meeting with NSX specialist in Japan and recently, I was informed of quite scary engine failure mainly on C32B engine.



    I spent more than a week to carefully consider whether I should share this information or not, as the cause of issue is still not clear.


    Also, I didn’t want to cause too much concern for the owners and ending up keeping NSX off the road.


    At this stage, the cause of this issue is not clear and ...

    As pointed out to the owner last time, it was possible that the noise was coming from the cracked welding at the exh. bracket.


    So, to test it, I applied high temp non-melting grease into the cracked section.


    It made some difference but still some noise was there.




    There were two exh pipes with only about 2mm gap at the rear left side of the aftermarket exhaust but even when ...

  3. CAT & Exh. area noise revisited… Part 1

    by , 08-02-2011 at 11:31 PM (Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer)

    Recently, I worked on one of the NSX for the squeaking noise caused by the Front CAT heat shield scratching against the metal bar at the aftermarket diffuser.



    After testing the car on the dual carriage way and some heat soak condition as seen in my Blog dated 28/Jan/11, the car was returned to the owner.


    Unfortunately, when the owner got off the motor way and drove into the city area, he started to hear the noise again.

    He also ...

    Good call to replace the header tank. It was already cracked and leaking the coolant.


    The coolant hoses were also didn't feel healthy so at the time of TB/WP service, it would be best to replace all of them.

    You can replace the header tank without loosing too much coolant but I always bleed the air afterwards

  5. Crank Pulley Part 2 and other....

    by , 05-02-2011 at 11:48 PM (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
