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

Despite the poor oil maintenance by the previous owners and
human errors by the previous services, the condition of
the camshafts were surprisingly very good.

There was no noticeable marking on any of the cam robes and
just tiny marking on some of the journal area.







The limit of standard service.

While you may be able to wipe off the surface sludge inside the engine,
you will never be able to clean the parts especially the hidden area of each parts
without removing the cam shafts.

These are the cam holder plates that have very important oil jets.

The back side of it was covered in sticky thick sludge (right one).
With the amount of sludge, you never know how much dirt managed to
nest inside the very important oil jet unless you remove the cam plate.

Cleaned it to this level (left one) and also checked each oil jet by
blowing the air through each holes.







So, after spending hours,
finally the very dirty front bank cyl head became like above.

Quite happy with the result because it looked like below before the disassembly.
Lots of sticky sludge, excessive amount of liquid gasket all over the place, etc and
no need to tell the sludge/gunk that you won't be able to see without
removing the cam shafts......













The cam pulleys installed and torqued to the spec.







Replacing the WP.
The original one was making high pitch squeaking noise when spun by
hand so glad we replaced it this time.

As mentioned previously, I saw several seized WP on NSX including
the one at my local Honda garage.....

Cleaning the old red sealant.









While I have better access, cleaned the upper two bolt thread at the oil cooler.







New design WP installed.









The oil pump seal (crank seal) was dry so going to re-use it.
In Japan, it is very rare to replace this on NSX although
I keep one spare at my place.

For some of other models, people prefers to replace it at the time of
every TB service.



Time to install the TB and then the 4Hr marathon of valve clearance adjustment.



I should have painted the valve covers in advance because the
weather forecast for tomorrow is not good.....
From here, things will speed up a lot....



Will contact Bigg Red to see how they are getting on with the polymer coating.


More to follow later.
