: Exhaust valve question

07-23-2010, 09:29 PM
Hey guys, making some headway with this. Just a question, when the car is off, should the valve be open or closed? Mine is closed. I try to move it, but the valve wont budge. I even had a buddy rev the engine to 3000RPM and it still looks closed. Do you think its siezed? I have a 2002 e65. Im wondering if the gold tee thing will work.

I spent some time today figuring this thing out. I have a question, is the exhaust valve supposed to move freely, because it's jammed shut. i could noyt open it at all. On top of that, I didnt even notice a vacuum in the tube. Even revving the engine, there was no vacuum at all. This might be siezed. Any ideas how to get it open?
