Some theory about the swirl flaps for BMW diesel.

On the BMW diesel engines M47 and M57, for the sake of reducing harmful emissions, installed with the intake manifold flaps “vortex channel” motors with such collectors were issued until 2010.
While the new car, these dampers are working properly and not bring trouble to the owner of the car.
However, with the aging of the car they wear out.
As a result, first, there is backlash in the damper axis, because of that the charging is leaking air and oil.
The engine starts to “sweat” oil, in the most severe cases, the oil simply drains all but down the creek.
Then, as the progression of wear, stop valves open and close properly and in some point of the wedge in the closed state.
The result is a reduction in engine power by about 10%, but it is not so scary.
There is a risk of breakage (breakup) of these dampers and their penetration into the engine cylinders.
Hundreds of examples of such breaks can be found on the Internet.
Engine instantly incapacitated and in need of major repair with replacement of pistons, valves, etc.

We fabricated aluminum caps, which are installed in place of the swirl flaps, eliminating the problems described above.
