After initialising the parking brake mechanism, adjusted the parking brake cable.









Before installing the eng bay vent, applied this in order to reduce the amount of water pouring over the rear valve cover section.
Tested it for months including summer and heat soak situation without any issues with lots of mileage using my NSX.
It will guide the water towards the TB side of the engine near the RR damper top mount.

Not perfect solution at all and won't be able to cope with the powerful stream of water like when using power washer or even the garden hose but at least,
it can reduce the amount of water pouring over the rear bank IG coil area when the engine is not running and the NSX parked outside in the rain.

Once the vent is installed, you can’t see this unless you open the hatch glass and get your head close to the engine.






However, unless you cover this opening, some water will enter the engine bay so I used EPDM sponge on my NSX but looks kind of out of space and also
the water can't go anywhere so tends to stay on the flat section of the vent.
I better leave it to the owner so kept it untouched.


If you want better protection, you should consider Jonathan’s nice metal tray.











Final adjustment made to the base idle air setting, checked the IG timing and sealed the adjust screw.
Until next time when you replace the coolant (in about 4 - 5 years for Type 2 coolant), you can just use spray type cleaner without removing the TH body.









Removed the air box again and compression check after the Eng Refresh.
Somewhat I already knew it would be a good result as the engine sounded so smooth.

The deviation between each cyl got much closer so very happy with the result.
The data has been emailed to the owner.










Already posted this a while ago but silicone grease applied to the iG coil head as well as tiny amount at the tube entrance.









Same thing on the IG coil cover gasket. Hope it will stay fresh for a long time.
