Excess crankcase pressure is vented from the crankcase through the PCV system, where it is drawn into the intake manifold and returned by the engine. This recirculated air contains aerated oil from the crankcase which is burned by the engine. Turbo charged engines often draw significant amounts of oil into the engine through the PCV system. This oil catch tank system removes aerated oil so that it can be drained and recycled.
This kit is suitable for intallation to the 2 litre FSi engines found in the VW MK5 Golf , MK5 Golf Edition 30 and SEAT Leon Cupra ( not for engine codes CCTA CBFA ) The kit is available in two versions, as in different geographic locations these vehicles are fitted with a charcoal filter, located at the front of the engine bay ( on the left as you open the bonnet / hood )
We spent significant amounts of time on every last detail of this kit, incorporating everything necessary to completely bypass the stock PCV system while actually providing increased operative function. The kit is recirculating in design so as to maintain emissions compliance, however, it will capture all of the aerated oil, fuel, and water vapor contained in the blow-by gasses that would otherwise enter the intake tract and potentially contribute to deposits on the intake valves, thereby keeping the intake system clean and the engine performing optimally long-term.
The kit incorporates features such as:
A unique feature included with the kit is a double-o-ring sealed clip-on intake manifold cap with three available ports to source a vacuum/boost reference for various engine accessories, such as a boost gauge, bypass valve, or a water/methanol injection trigger. Any unused ports can be plugged with the included grub screws.
If you have ever wondered just how efficient these kits are at removing the sludge and oil, take at this:
Aerated vapors in the blow-by gases are only partially responsible for intake valve deposits. Installation of this product will only partially limit the potential for these deposits to occur. Intake valve deposits can still form to some degree due to seepage of oil from the intake valve guides.
