Low turbocharger boost pressure and low engine performance can be caused by leaks in the charge air cooler or 
plumbing. Fuel staining on the exhaust manifold can also be an indication that there are leaks in the air system. 
The following procedure outlines how to check for leaks in the charge air cooler system. 

This procedure can also be used to check for leaks in the wastegate signal line or the wastegate canister.

1 - CLAMP
2 - TURBOCHARGER
3 - AIR DUCT RUBBER SLEEVE
4 - AIR INLET DUCT
