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

Intake manifold back in place together with Eng Loom.
Some of the bolts were the wrong spec so looks like someone worked on the
engine in a hurry.






This NSX is non-DBW model so it has the EACV and the fast idle valve.
New o-rings and meshed filter installed.
As always, there were lots of black carbon trapped at the original filter.
If it gets worse, it will cause idle rpm issue.







Back on the engine.
Didn't like the way the fixing bolts were corroded so decided to replace all of them with
new one.




The fixing bolts at the heat shield will corrode again so not sure
whether it’s still worth re-installing it or not....
I don’t use them any more because I have aftermarket header.
I even removed the ones around the CAT because they were rattling and
making squeaking noise.

New O2 sensor will be installed on both F & R bank as the existing ones were
covered in black/brown debris.




Time for the 4Hr marathon valve clearance adjustment.

By not attending the Donington Historic Event and worked through the weekend,
I was hoping to have the engine back in the bay by the end of Sunday.....
Still behind the schedule......


Considering the plan for this week with all sorts of projects,
it’s going to be very busy again.

I must mower the lawn today.....

More to follow later.
