Hi here are the pictures or the inside, there are four very fine wire that will break easily..... I think the best way to approach adjusting the angle of the connector (assuming you get the pins out smoothly, I'm going to look at tapping them and using a tiny screw to pull them out) Is to spray a small amount of silicon spray to lubricate the big o-ring and then twist the plastic top connector to the desired angle without pulling it off the metal housing. You will see that there is a key and key way that links the plastic connector to the inner workings.

I hope someone can learn from my mistakes

For the intake removal - I found this very helpful for some of the awkward bolts - wera-zyklop-1-4-drive-bit-ratchet-set-38-pieces (always good to have an excuse to buy tools) :-D

from the pictures, looks like the side of the motor was glued to the plastic housing while the top (where the connection goes) is not removable because the pins are soldered ?

i will probably take mine apart before trying to do the same with new one. HOWEVER

do any of you uys know which voltage the valve works ?

There is no glue involved in securing the insides, the blob of sealant holds a piece of plastic film that prevents any electrical contact from the wires to the metal body.
You could remove the whole internal mechanism by pushing from the bottom (the metal valve end) the whole lot should pop out of the top, just be aware that the four wires are beyond fragile.

Update: SJ's have no more stock

maybe its possible to remove it from the housing and reuse the housing of the original one in order to ensure the connector direction stays ?

That might be possible, but I would say drilling the holes is more straightforward. I have done mine and re attached to the manifold..... now to reconnect everything and fire it up - will report back
