SAAB 93 FACTORY DEFECT THAT COST YOU BOOST

Hello everyone,
In this video you will see what is the proper method of testing your intake system for vacuum and boost leak using the smoke machine or pressure source and soapy water.
I will show some of the most common usually overlooked leaks, that include a factory defect in all saab 93s with the mitsubishi turbo.
The most overlooked boost leaks are :
1. The PCV valve, which cause an internal boost leak and many other symptoms like oil loss, smoke...etc.
2. The bypass valve diaphragm, is another internal leak that require full understanding of the system to be able to diagnose.
3. The factory defect, a missing gasket between the bypass valve and the turbo body.
4. The forth one is a vacuum leak, located at the point where highest vacuum is achieved during driving under boost, the O-ring at the tip of the rear PCV hose where it bolts to the turbo inlet.

If your car has the B207R, or your car has any version of the B207 but made after 2006 then you probably have a mitsubishi turbo.

O-rings used:
Turbo inlet PCV ID9.8 CS2.4mm
Charge pressure Sensor ID8.8 CS1.9mm
