    Just keep removing the parts….


    Noticed that during the last TB service, some of the bolts for the TB mid covers were not placed back and missing.


    Not the first time to see this and quite common human error, I’m afraid.

    Due to the valve cover gasket not replaced or not installed properly during the last TB service, there were lots of oil seepage behind the crank pulley. ...

    At #1 & 2 spark plug, there were noticeable amount of engine oil around the HEX bolt section.


    During the Health Check last year, I also noticed significant amount of engine oil seepage at the rear bank exhaust bank.



    Based on these, it looked like the valve cover gasket, spark plug hole seals, etc were not replaced during the last TB service.

    After the initial inspection, I noticed that someone worked on this NSX in the past.


    Last year, when I spoke with the owner, we couldn’t find some of the service history record at the time of Health Check but we were quite sure that the car had TB service in the past.

    Time to vacuum fill the coolant.


    Another leak check as I removed the header tank after carrying out the last check.


    Honda Type 2 coolant in the system now.


    Connected the battery and warmed up the engine.


    Quick adjustment on the ACG and A/C belts as they expanded a bit.


    Again, they need to be re-adjusted in the future.
