Hey all, I think I have an air leak on the non pressure side of my turbos. I have noticed recently slightly more boost noise, and much more blow off valve noise, but no loss of performance. I checked the hoses coming off the blow off valves and they are fine, and every hose I could see, all are fine, but I have not yet checked where the pipes go into the turbos. Anyone have any tips as to the easiest way to inspect them? I am gonna put it on ramps this weekend and see if I can look from the under side. Any pointers would be appreciated.
Thanks
Here are some pics of the rear turbo & Front turbo piping high-lighted in red. Z
Did you check for any codes set?
I would make certain every hose clamp is properly secured and would also visually inspect the front turbo piping,CAC,intercooler for any split hoses.
I would also check the BOV for any signs of oil.

Mine were loose and also causing some pcv oil leakage that looked to be coming from the feed/return but was just from the pipe circled in blue being loose. Make sure the car is cold because you will be getting very up-close and personal with the underside of your car lol.
Thanks all!!!
