The WP is the latest spec so it had its TB/WP service in the past but old spec TB lower cover was still in use.

Someone modified it to accommodate the later design spec WP.















As seen on many NSX, missing some of the bolts….















This gasket is dislocated and caught so not making any good sealing…..















The oil cooler top hat is not too bad.
Some rust but still in very good shape.

Once again, the coolant hose is not pushed far enough and the short one at the upper side is kinked......

Covered in oil as well so going to replace both of them.
















As reported earlier, the front valve cover had eng oil splashed for years now so can't clean any further before removing it.
Will deal with it later.

The rear valve cover..... The usual water markings and dust/debris......
I hope I can clean it enough without stripping the old paint......
Not looking forward to it......

















The #3cyl spark plug seating area.

Despite the rusty looking, the seating area itself looked fine.

Carried out another leakdown check (but with cold engine), fibrescope inspection (this photo is from the front bank), etc and
advised the owner with the same instruction as other owners to keep monitoring the compression data at least once a year and
I'm going to clean this area as much as possible once the valve cover is off.















Missing the harness bracket but the tyrap holder at the eng loom side is also gone…..

If available, will get the bracket from Japan.
