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

The owner already mentioned this to me and I agree with him.
I don’t like this spring that came with the aftermarket header.

Because it is not properly manufactured,
It doesn’t sit parallel to the bolt.
I can’t compress it too much as it won’t act as a spring if I went
too far.








Intake air temperature sensor.
Looked to be cleaned in the past but covered in lots of
oil and also some debris.

Cleaned it and installed it with new O-ring.










The front intake camshaft (2nd one from the top) was
showing extra wear compared to other three but still,
the coating was in healthy condition.

Again, the proof of super low mileage on this engine.










After degreasing the surface, applied dash of black paint to
make the valve covers look clean.

In fact, I spent more time cleaning the inside of the valve covers
as there were sticky gunk from the blowby gas.









Removing the red sealant before installing the new WP.













The old and new WP.
