Wow, what a mess around the rear bank cam shaft seal disc.




Proof of the old original WP design from the factory.
You can no longer get this design for the WP as well as for the
TB lower cover.
Both were upgraded to the new design.

Someone didn’t put the fixing bolt for the TB rear cover.






The rusty oil cooler.
For the ones started to leak oil, they were showing the heavy corrosion
around the top surface near the 10mm fixing bolt for the
low oil pressure warning sensor cable.
On this NSX, it was interesting because the heavy corrosion was more towards
the area behind and around the coolant hose connection.
To be on the safe side, probably best to replace now or in the near future but
will discuss this with the owner.
