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

[Edit:] Message to the owner
Forgot to mention this in the previous post.

Despite having the later spec LMA, to my finger, the one at
the Inlet side of the #4 cyl felt tiny bit weaker than others.
It is possible that it's just my imagination as I didn't measure
the spring rate and just felt with my finger.
Nothing to concern and won't cause noise issue probably even
after the next TB service.

It's the same on any low mileage NSX.

When the engine is stopped, some of the mid rocker arms are
pressed down against the LMA by the cam robe while the others are
in free position. Until the next time you start the engine, the LMA is kept in
this state and hence, the fatigue at the LMA spring especially with the
1st and 2nd generation design.

Please try to use your NSX a bit more regularly in order to save LMA
as well as preventing the moisture inside the engine as you can see
in the form of rust at the back of the valve cover.
Although all looked fine, the same thing will happen on the cam robe,
rocker arm, valve top hat, LMA top hat, etc.





Cleaned the inside of valve covers and installed the new
rubber gaskets and seals.
Couldn’t remove the rust any further from the front cover….



Before closing the valve covers, hand cranked the engine many times
while applying the fresh eng oil.









As always, dealing with the liquid gasket so just the end result.
Both valve covers are now back on the engine.




Apology for the poor camera focus.
Was trying to show the application of silicone grease around the
IG coil tube and base.

Same treatment on the IG coil cover seal as well.




It’s the later spec NSX so of course, it will use P08 series gaskets
at the VTEC spool valve.

There was no oil leakage but with LEV model, there are so many pipes and
tubes inside the engine bay so better to service it while the engine is out.




Installed with all six bolts replaced.




Cleaned and new o-ring at the Oil pressure sender unit.
Another place where the oil seepage can happen.






Quick detailing of engine before placing it back in the bay.

New A/C and ACG belts installed and ACG back in place.
Will adjust the belt tension after the eng fire up.




The area around the cam shaft black disc should look like this
after installing the valve cover.
No excess liquid gasket left in the area, please.



So, the mechanical side of the eng service is done.
Just need to deal with three coolant hoses, thermostat, CL slave cyl,
CL hose, Fuel filter before placing the engine back in the bay.

More to follow later.
