The Oil Catch Tank Kit from Forge Motorsport is one of the most complete oil collection systems currently on the market.Excess pressure is usually vented through the PCV system, which is then drawn back in to the intake manifold and then goes back in to the engine. This recirculated air contains aerated oil from the crankcase which is burned by the engine. Engines which are Turbo-charged often draw large amounts of oil in to the engine with this process, reducing its ability to breathe and making it less efficient.Designed to capture the maximum amount of harmful contaminants which include oil deposits, unused fuel vapours and excess moisture. This oil catch tank system removes aerated oil so that it can be drained and recycled, allowing the engine to breathe and run efficiently.
