2.5 TFSI EA855 evo High End Oil Catch Tank Kit BAR-TEK®

The DAZA or DNWA is already an extremely robust platform for achieving high performance. The standard PCV of the EA855 Evo DAZA engines works without any problems at series outputs or low power increases. With higher power increases (more than 900 hp), the flow of the OEM PCV reaches its limits. This results in increased pressure in the crankcase. The increased pressure can lead to a "backlog" of vapours in the crankcase, which in turn leads to a loss of power, increased oil consumption, possible seal failure and a shortened service life of the engine. Our kit supports the existing PCV by increasing the flow capacity of the system rather than removing the OEM unit completely. To do this, we use a check valve that only operates when the crankcase pressure rises above 0.5 PSI. The valve then opens and releases the excess flow to the breather tank. To reliably measure the pressure in the crankcase, we recommendour pressure sensor. Easy to integrate and always reliable values.
