Eng Refresh + LMA, etc 46

Rate this Entry















Difficult time for everyone but life moves on.
Hope the owners, family, friends are all safe.












Pretty much this side of the engine is ready for re-connecting the battery.
Not everything back in place but already making huge difference on the appearance.
Before/after.














Managed to drain further about 300cc of old eng oil from the top.













New OEM short filter filled with fresh oil.
















The Honda ATF-DW1.
For now, I filled the gbox with 4.5L after draining about 5.2L.
Will adjust the level once fired up and after the test driving session.
















Treated the new header tank with 303 protectant.
















One benefit of huge delay in service is that I now have the eng glass hatch damper.

I never had problem sending these from Japan for many years but for the first time, the package was held by Japanese authority.
I have no idea how they managed to detect such small amount of high pressure damper gas packed together with so many other metal parts but any way,
had to find alternative method.

I know one courier company can air freight the suspension damper but not cost effective for just this small parts.
Fortunately, my boss was about to return from Japan so asked her to hand carry them back with no problem.

As seen on NSX Prime, addition to the boot lid damper, Showa is now manufacturing these in China.
No problem as long as the quality control is done properly.













New GND cable and battery back in place.
As mentioned many times, never over-tighten the battery clamp.

If done properly, you should see some gap at the craw.

    Hi Kaz,
    This looks to have been a particularly challenging engine refresh, but you've worked your usual magic on it.
    I noticed that the battery setting plate on this car has lost all of its black plastic coating due to corrosion. The plate sits very close to the battery terminals and clamps. If the plate came into contact with the +ve terminal, I suppose there would be fireworks. Is this something to be concerned about?

    Hi, Peter.

    Yes, it's turning into a big challenge due to new issues showing up every time after I started servicing the NSX that I have never serviced before but I like new challenge and still enjoy it.
    That is the most important thing.
    Just feel bad for the owners waiting in the queue for such long time but their NSX could cause another delay to other owners so I just keep pushing….

    Regarding the battery holder/setting plate….
    The above photo is for the GND terminal and for majority of the production cars, the chassis is at the GND level so having no gap is not a problem.
    On the +Ve side, the holder plate has specific cut-out to prevent the battery terminal/clamp from shorting to the GND.
    Therefore, if the plate created the short circuit, the car has either bigger problem or the plate was not installed properly.

    Quite often, I see the plate installed in the wrong orientation with the cut-out placed at the vertical wall of the battery body resulting in the kind of worry as in your post.
