A view from under the car through the front subframe opening. The generator
cable and the intake manifold stay get in the way, feel free to remove them.
Disconnect the negative cable on the battery before doing that.
Oil trap bolts
The oil trap comes next. All bolts here are 13 mm. Disconnect two upper
hoses and one lower hose before pulling the oil trap out.
Theoretically, you should pull the hoses out while the oil trap is still on
the car, but I've found it easier to do them afterwards.
The turbo inlet hose socket has a plug with a small hole in it, about 3 mm.
The service bulletin suggests drilling it up to 10 mm.
Keep the oil trap upside down while drilling to prevent the shavings from
getting in. Blow clean and wipe it throroughly afterwards.
The hole is much bigger now. Install the oil trap back and connect the lower
hose. Don't forget to reinstall the parts you removed to get to the oil trap.
Oil filler pipe
The next step is to install a nipple on the oil filler pipe. Remove the
dipstick and unbolt the pipe with a 10 mm socket.
The hole should be drilled 20 mm up from the ridge in the pipe, 135 degrees
from the lip with a mounting hole.
Use a 7 mm drilling bit, remove all the shavings and wipe the pipe after
Fit the nipple so the threads just become visible on the inner side.
The small hole on the nipple should point down.
Locate the hose that used to go from the small nipple on the fat hose from
the camshaft cover to the check valve. It should now be connected to the
nipple on the oil filler pipe.
There's little clearance near the filler pipe nipple, so it might be
easier to disconnect the hose from the check valve and connect it to the
nipple first. Pull it between the fuel rail and the wiring harness and
reconnect it to the check valve then.
Cutting the hose
The thick hose that goes from the turbo inlet pipe to the oil trap has to
be cut at the height level with intake manifold.
Insert the check valve so the arrow on it points upwards when the hose is
installed. You may notice that the valve is harder to blow through in a
certain direction, this is supposed to facilitate a different air flow
within the circuit.
Plug the small nipple on the camshaft cover hose with a cap supplied in
the kit and install the two remaining hoses on the car.
Here's a summary of changes: a bigger hole in the oil trap, a check valve
on the turbo inlet hose, a nipple on the oil filler pipe and a new
attachment of the small circuit hose.
