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

Was planning to attend the Donington Historic event this weekend but
with so many things to be done at the moment and my boss flying back
from Japan on Wednesday, decided to work on the eng through the
Bank holiday weekend.
Sad......




Regardless of whether you have NA1 or NA2 engine, it is always better to use
the exh manifold gasket, stud bolt and nut designed for NA2 one.
This is because the NA2 gasket has slightly larger diameter for the oval opening hole
for better flow, nut has better treatment/shape against the future corrosion and
the stud bolt is shorter that it reduces the chances of getting extra corrosion.

This is the same when installing the aftermarket headers.
The design of some of the parts/gaskets included for the aftermarket headers are
so poor that I normally don't use them.




As mentioned in the previous post, although it is very unlikely to fail,
you will never know when it will happen so while the eng is out,
just replace the CRK/CYL sensor if the potting has melted away a lot.






As always, no time taking photos while dealing with the liquid gasket so
just the end result.
All four cam shafts, holders and plates back in place.


They were covered in charcoal black like this so much better now.




When it is done properly, your cam shaft end black disc should look like this
with the liquid gasket filling the gap along the outer edge but
no excess left around it.
This is the same when installing the valve cover gasket.
So many times, I saw excess amount of liquid gasket left and spreading
outside/inside of the valve cover.
