Boost leak
Hey guys, I have a leak some where , wether its exhaust or intake im not sure.
Im looking for so ideas/ methods on how to check for a leak. Without unbolting anything yet everything looks good. No leak at the header gasket or cracks in the header. Turbo flange looks fine no soot.. Usually i would see a crack or something. Intake looks good. All connections seem fine nothing jumping out at me so far. The leak on a scale of 1 to 10 is a 5 just to be clear. All (3) silicones are all good no obvious leaks. Anyone ever test there system in the car? I was thinking of making a block off plate for the rear of the turbo and disconnecting all the rockers. Then put compressed air to it . What do you think? The only thing i was thinking that might leak would be the oil ring seal in the turbo.. Then for the intake i would block off the inlet at the turbo and do the same test. Anyone have any ideas ? Thanks...
