2.5 TFSI EA855 evo crankcase ventilation kit BAR-TEK® BAR-TEK Motorsport 21rs3106 - сервиз

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 power loss, increased oil consumption, possible seal failure and a shortened engine life.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 utilise a check valve that only operates when the crankcase pressure rises above 0.5 PSI. Then the valve opens and releases the excess flow to the breather tank.
