THE- RS4/S4 oil catch can set
This set is a cyclone oil separator. This works as follows: the vapors from the crankcase ventilation are directed into the side of the container. By hitting the side wall of the container and rotating, the oil film collects on the inside, flows down and is returned directly to the crankcase (this means the container does not need to be emptied). The remaining excess pressure can escape upwards through the intake -Y. When using the THE - oil catch can kit, the original hoses with T-connection (which are usually porous or broken) are replaced. On cars with secondary air system the secondary air pump must be removed, because this space is needed for the oil catch can kit. Suitable plugs can be found under our products (Art. No. THE-B5 003 00). The small silicone hose is responsible for the exhaust air of the N75 valve. This can be mounted at the original position of the valve. The stainless steel holder of the tank is screwed along with the intake manifold on the left rear. The original screws can still be used.Additional information:
The set contains two hoses - one for the S4 and one for the RS4 intake-Y (see picture). The respective hose is the connection between Y and pressure control valve (see pictures).
With the S4, there is no line to the F-hose. The connection on the F-hose must be closed or replaced by a straight hose. These parts are not included in the set.
The pressure control valve is not included in this set. The original can be used or a new one can be ordered directly from us.
In order to create better space and to eliminate sources of error / leaks, we recommend using our vacuum check valve set with item number THE-B5 022 02.
It can happen that silicone hoses have to be shortened minimally in order to achieve a perfect fit.
Do not try to take the lid oft he catch can apart! It breaks when the cover is removed!
Please remember that these components are not permitted in the StVO.
The oil catch can set is not suitable for cars that have an intake manifold with push in ports installed, for example, as in the newer Audi A6 models!
