Gen V LT 4 Intake, MAF and PCV Plumbing

This view shows the new style PCV system with the intake plumbed with the stock lines from the Cadillac CTSV.  These are metric fitting and aren’t easy to adapt to, so I used a aftermarket Spectre vacuum accessory kit to plumb into the intake.  You can see the line with the extra foam rubber wrapping around the line that goes into the intake.


On the right side is one of the Intercooler lines hooked up and connecting to the expansion tank (far left square alloy tank.)  Right below to the right is the MAF (Mass Air Flow) connection that has to be a minimum of 10″ from the engine.
