![]() ![]() * If using the exhaust pipe exiting the turbo for vacuum, 1 way check valves must be used to prevent exhaust gas circulating back into the crank case. ![]() * If using the intake pipe leading into the turbo for vacuum, source must be after the MAF (if equipped). * If using the intake manifold as a vacuum source one must use a 1 way check valve to prevent the crank case from being pressurized when under boost. * Vacuum sources generally used are intake manifold and intake leading into the turbo. * Best results are found when the crank case is experiencing vacuum. * Either venting through a breather filter, catch can with breather filter, intake manifold, intake pipe, or exhaust. * Crank case must vent pressure that accumulates in the engine. Here are some examples of how you may setup your PCV, Catch Can, Breather Can, Vacuum, etc system: Ok now that you have researched and read through those threads… Previous threads which contain dialog of RB owners configuring their PCV and catch can setups (the good, the bad, and the ugly)…įor pictures of factory, modified, and custom setups: The info needed is not limited to what is found solely in the RB section in which this thread links to previous threads, but the same principles follow much of all other motors.
