i am trying to diagnose this by myself becasue i am sure if i go to the dealer with this question they'll like take my car and not do anything, then 2 weeks later give it back to me saying they fixed it when they didnt. i hate my dealership. anyway, when my turbo spools i am familiar with the high pitched hissing sound. lately, a new hissing sound has been coming from the drivers side of the engine. now there is the turbo spool noise, and this hissing sound which sounds like high pressure air rushing out from somewhere. are there any hoses turbo related in this area that could have cracked? i know my intercooler is there... i also feel a slight loss of power. not much, but it feels like less. any help is appreciated. thanks

 

The intake manifold piping is there along with alot of vaccum hose connections.
