Whats wrong with this part?
Going to all the effort to compress the air into the engine, but its leaking out!
A close up of the air duct from the Charge Air Cooler to the Engine Air Inlet.
Here is where is was mounted up to. The round boot is leaking up to the Engine Air Cut Off Valve. Otherwise known as the positive air shutdown, or DEACO valve.
When it was installed it was rubbing against the plastic fender liner. Amazingly the fender plastic has NO wear on it whatsoever! Inspect regularly to make sure the moving and flexing hoses and harnesses between the engine and the frame/body are not rubbing.
