I changed the hydraulic valve.

I see that it has a notch, but i cannot fix it with that notch.

I tried to fit it exactly and srew the 2 e10 bolts.

But i think it moved a little bit.

Is this a problem or can i try start the engine and see if it runs on 6cylinders and not on 3 like it did before?

 

I dont know how it is called in english.

It is the part that you can change when you remove the y-pipe and the air filter at the back. (It is fixed with 2 E10 Torx srews)

I put out the old one and tested it with a battery - it makes a noise like Clack.

What should happen whet it gets power?

 

Thats the part iam talking about:
