Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Clean cut of the heavily corroded CAT stud bold/nut.
I'll extract the stud bolt once the engine is out of the way.
Probably use the ball joint separator.

You can see the heavy corrosion even at the hidden section of the bolt body compared to the other one in the photo.
Fortunately, Honda UK offers some of the exh area bolt/nut at exceptionally cheap price so just the labour time.







As experienced on many NSX, the fixing bolts for the U-shaped bracket under the eng/gbox were all oxidised.
This one was so bad that as soon as I started applying the torque, it made loud squeaking noise and at that point,
I already knew that even using the back and forth motion, it will sear off.
I couldn't turn it a lot and the bolt seared off.
You can see the loss of dacro coating where I managed to rotate the bolt.

If only someone spent a little extra time applying dash of silicone spray if re-using these dacro coated bolts…..
The shape of this bracket and the way it’s held, can live without drilling it out so will decide what to do later.


Another issue was the FR brake pipe fitting where it meets the brake hose.
Normally, front side is far better than the rear one but on this NSX, FR fitting was completely seized and bonded to the pipe that
if I try turning the fitting, it will simply twist the pipe.

I could disconnect the fitting by rotating the hose side but that means I won’t be able to install the new hose without twisting it.

Therefore, I’m afraid the FR brake pipe has to be replaced as there is not enough pipe length for installing the replacement fitting and creating new flare….
That’s going to be an interesting challenge as I must replace this brake pipe without removing the classic ABS modulator blocking the area….










Although there was no crack on the coolant tank, it’s definitely leaked in the past as the direction of the markings were all the same and can’t be from the spillage.













The cyl head cover gaskets were replaced several times in the past and the side of the engine looked to be cleaned at the same time so
it’s been a while since last time I saw fairly oil free eng block although the oil pan gasket is leaking and the gbox case is dirty.
Will wash them really well.
