As keep cleaning the engine with one's head in similar position makes shoulder stiff, decided to change the rhythm of the activity.
The first package for the extra parts arrived so started replacing auxiliary components.
New bearing for the a/c idle pulley.
You can see the partial crack on the pulley itself at the lower section of this photo.
Overlaid the new belt and the cracked section didn't touch any part of the belt so happy to re-use it.
New rectifier. Apology for the poor focus....
Looking fresh and installed.
As reported earlier, the rear header was hitting the sub-frame so decided to take a look at this stage.
And yes indeed. It was hitting for quite some time.
Considering the design/material/shape/etc, I don't have enough confidence in making big enough changes to the header side to
prevent it from scuffing the sub frame and obviously, you don't want trimming off the sub frame so
going to see how much changes the new front eng mount can make.
By the way, the owner was still using the NA1 spec stud bolt, gasket and nut with the header.
I always recommend using the NA2 spec ones but these are something 'better' and not a MUST process.
The diameter of the NA2 gasket is just a bit larger (overlaid NA2 spec over the NA1 in the photo, about 1 - 2mm wider so less friction but
considering the exh gas speed, by how much???) and the nut has better treatment against the future corrosion.
The stud bolt is shorter so it won't heavily corrode all the way.
After discussing with the owner, we are going to replace the gasket and the nut to NA2 spec.
The stud bolt looked to be replaced in the past and all 14 of them are in very good condition so just going to leave them.
