Description
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.
