I have read the FAQ's and guides about boost leaks but still have a question. The leak sounds like it is coming from the rear of the engine on the passenger side but I can't pinpoint the exact spot. My best guess is that it is coming from or near a tube wrapped with a silver sleeve which I believe runs from the exhaust manifold to the EGR. Is there anything near this tube to cause a leak or do you think it would be the tube itself? I tried to do as much GOOGLE research as possible but still need advice from the "Experts"! Thanks
