As in my last report, took the photo of old/new idle air adjust screw.
Unless doing DIY, quicker and cheaper to simply replace it as it comes with the new o-ring that you must replace any way.















Over the weekend, the temperature was kind to us and with the support of garage heater, carried out the marathon 4Hr task of valve clearance adjustment.
As I didn’t want changing the rhythm and the finger touch, couldn't take any photos during the process so just showing the preparation stage and the end result.

All 24 valve clearances carefully adjusted and checked in 3 rounds.
Really time consuming task and you can’t take any break but very important for creating the rhythmical smooth eng sound.







Front mid cover torqued to the spec.











Not closed the valve covers yet but will do so today.




I really need the oil cooler today......

    Is it possible you recorded a video/sound before and after adjustment valves. I have seen on You tube your videos.
    ???

    I took several videos in the past and uploaded on Youtube but there is no direct comparison of before/after just the valve clearance adjustment without changing any other parts.
    I only adjust it as part of my Eng Refresh.

    In my personal view, one should not touch the valve clearance on NSX engine until one really has to do so despite it is specified as part of the maintenance schedule in some of the countries.
    With the eng kept inside the bay, it's not an easy task especially at the rear bank.
    I used to spend even more time just for this task when I used to do it without taking the eng out.

    After carrying out the Eng Refresh on my engine, I never touch it until after 60K miles or 10 years time whichever comes first and each year, I’m taking the eng compression but no changes in cyl tendency so I'm happy with it.
