The stock PCV on the TFSI engine is quite fragile and over time, or when running lots of boost, the diaphragm inside can rip which can result in excessive blowby entering the inlet manifold at idle (smoking from the tailpipe) or a loss of boost when driving, which can cause other problems.
Traditionally we fit a catch can to remove the PCV entirely and catch the oil vapours from the engine as seen here: FMMK5CTC and FMMK5CT.
But if you want a cheaper and simpler solution, you can delete the PCV and divert the breathing to the rear cam cover outlet only, by using our Forge Motorsport PCV delete kit. Simply put, it removes the PCV and links the two internal ports together which emulates what happens inside the stock PCV when the engine is on boost, but without any fragile components to break or split. This completely isolates the inlet manifold from the cam cover.
The kit also blanks off the port on the end of the inlet manifold that used to go to the PCV, and replaces it with our FMBGFK2 boost gauge fitting kit. This comes complete with 3 vacuum hose takeoffs and blanking screws so you can run a boost gauge, water spray controller, or you can blank them all off, it’s up to you. The kit comes complete will all parts necessary for installation and a full set of instructions.
