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. The kit is suitable for intallation to the 2 litre FSi engines such as in the VW MK5 Golf , MK5 Golf Edition 30 and SEAT Leon Cupra (not for engine codes CCTA CBFA).
Depending on geographic location certain models listed in the compatible vehicles drop down menu are fitted with a charcoal filter to meet local emissions regulations. The filter is located at the front of the engine bay (on the left as you open the bonnet); also see black plastic canister in the engine bay image shown above. This kit with part number FMMK5CT is for models not fitted with the charcoal filter.
If you do have the charcoal filter as standard an alternative catch tank kit is available under the product code FMMK5CTC.
Please contact us by email or phone if you are unsure of which kit is compatible with your model.
