    It was also noticed on the WP as well as on the TB tensioner.

    The colour and the material looked to be the same one as the melted potting from the CRK/CYL sensor which is normal on all of NSX but can’t remember seeing so much debris on the cam pulleys.


    WP and tensioner will be replaced with the new one and will try to clean the cam ...

    Despite the dirty valve covers, the internal engine components such as camshaft holders, holder plates, etc were reasonably clean that is very good news.


    Backed off all of the valve adjusters and removed the TB.

    While removing the Eng oil cooler, noticed that one of the two coolant hoses was already deformed and fattening.


    Sooner or later, it would have busted so glad that we decided to replace all of the coolant hoses this time.

    As seen on other NSX, upper two bolts on the oil cooler didn’t have enough sealant.

    Looks like it was not reapplied during the last TB service.

    The worst one was this one and most of other pipes were corroded as well.


    Polished carefully as I didn’t want to create another leaking point.

    What a long day….

    I found myself sleeping on the floor as I was so tired....



    Spent hours cleaning so many corroded pipes on the cooling system.


    As always, photo doesn’t show you the full extent of the time consuming task of replacing all 23 hoses on NA1, MT, RHD, non-DBW model….


    Normally, I find several corroded pipes during the hose replacement service but it’s been a while since last time ...
