This oil catch tank kit has been specifically designed for the Audi TT Mk1, with the 225 engine. As normal from Forge, the kit includes everything required for the perfect installation. We have custom designed hoses and a superb looking polished alloy tank that incorporates a sight glass to check the oil level.

Normally, 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.
