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

The eng/gbox assy is already out of the bay and all four camshafts are removed.
Must catch up updating the blog although the owner has been updated regularly through different channels.













Not sure what kind of coating this aftermarket mesh eng cover is using but with the UV ray, heat and splashed debris from the aux belts,
part of the area is turning into white markings.

In fact, some of the coatings are already peeling off and depending on the angle, you will notice white base colour.














Not impressed with the design of this aftermarket battery terminal.

Due to the narrow battery post of the NSX-R spec battery (I'm afraid the capacity spec is too small for this NSX…),
the terminal was replaced by someone but it was using two bolts to directly screw into the bare wires.

Should have used crimped or design that will sandwich the bare wires and not directly allowing the bolt to cut through them.

Can't do much as it could be waste of parts and money if the owner decides to change the spec of battery in the future.

Provided the owner with several options and what parts are required for each options because currently,
there is not much protection against the heat from the rad fan especially when the bottom side of the front compartment is completely blocked by the aftermarket plate.














Couldn't get good focus but the a/c idle pulley is partially cracked.
Probably not big enough to cause whine noise and there was no severe markings on the belt so should be able to just re-use it.
Later, after removing the eng/gbox outside, checked the cracked section using the new belt and there was no contact between them so going to re-use this pulley.














Although this NSX had its coolant hoses replaced, I think some of the hose clamps were re-used.
Already many of them were very rusty and chewing into the replaced hoses.

I normally recommend replacing all of them to new ones as you never know what would happen in next 10 - 15 years if re-used.
Some of them could be 20 - 30 years old at the time of next cooling system refresh.















Instead of using the extension cable, additional cables were soldered to the front O2 sensor for the installation of the aftermarket header.
Not a big problem but when the time comes to replace the O2 sensor in the future, someone is going to struggle…..
















Probably the same on your NSX.

All these sponge seals are either dead or already broken off in bits and pieces after all these years.
When I did my A/C Refresh, first thing I noticed was how much air was getting inside the cabin despite using the re-circ mode.
With these seals no longer working properly, you are allowing all the cold/hot air, smell, etc into the cabin.

Not much can be done apart from peeling it off and replacing with something similar.
EPDM or silicone is better but it depends on the shape of the mating surface as the shore hardness is one of the key factor for the selection.
