The only other engine type pic I am posting now. It shows another tube underneath. I take this to be a 'Zork' tube? from my reading of other posts.
If this is correct, can someone explain what this does, and is it useful for the engine. I have been told they are detrimental to the engine?
I understand it is for dumping excess pressure?
Any suggestions on how to check the operation of the over boost valve would be useful.
The 911 is a great looking car - I can sit looking at them for hours. They never date. But these things are WICKED.
Thanks
Alan
