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

Probably, one of the most neglected and missing parts from UK based NSX.

The dust seal at the TB tension adjuster bolt.

It will cover the gap behind the tb tension adjuster bolt head (the red marked one for this service) like this.


I can imagine some of you are now going out to have a look at your engine bay between the ACG and the Crank pulley.....


Do you have this seal on your engine?


You don’t want any moisture, dust, etc to land on your TB until the next TB service….



As I didn’t want to start the marathon Valve clearance service unless I can block the minimum 4Hrs session, decided to work on other areas.....
