WK CRD: Swirl Motor Question for the experts

Hi,
Can somebody explain the actual mechanism of how oil leaking form the turbo charger/intake area actually damages the swirl motor? Is the damage caused by oil electrically shorting it or some other mechanism?

Here is why I'm asking. I finally replaced the intake assembly with the upgraded one. I've had a nasty oil smell for a while and I can see visible smoke coming from the area when engine is hot. Is there anyway I can get rid of the oil mess without destroying the swirl motor?

I'd like to pressure wash the area after I soak it with some engine degreaser.

Thanks for your help.
Drew

You talking that the oil lubrication on the turbo is leaking into the compressor?

Hi
It's the oil getting into the motor that does the damage so washing it I would be careful was around it should be fine as it's only the EGR and oil coolers around it and the V of the engine as drain holes.
Regards,
Merlin

No, blowby gasses from the crank case ventilation system are laden with oil. A provent/racor CCV filter is mandatory equipment to filter them out. Prior to doing this, oil in the intake from blowby gasses would leak out the intake where the intake is mounted to the turbo (poor seal design) and remainder would damage swirl motor post turbo intake assembly.

Based on merlin's post, its the oil in the intake from ccv blowby gasses that damage the swirl motor.

I think I understand the Swirl Motor issue now. Is this correct? It's actually the leak at the mouth of the inlet to the turbo that is the root of the problem. It is the accumulation and POOLING of the leaked oil sitting on the OUTSIDE of the top of the engine between the cylinder banks that's the REAL issue. Does it then find it's way to the Swirl Motor as it runs around the outside of the engine? The oil vapor passing thru the CCV, thru the turbo and into the intake and intercooler (although not good either), is NOT the actual cause of the Swirl Motor failure. As long as I keep oil from leaking onto the top of the engine, I should be able to avoid this failure. And this is a design flaw inherent to the WK and other Chrysler applications and less of an issue on the Benzes with this same engine. Is there a picture of the swirl motor? I assume it's certainly not visible from the outside. Thanks for any dumbed-down explanations you can give. A bit of a novice wrench turner here.

I believe the swirl motor is in photo #3 of merlin's post.

The oil leaking onto the motor from the intake pipe is the primary reason for it to fail however oil going into the intake can clog up the flaps as you can see in my pictures.

SQ & MerlinTec,

Thanks for the help. 2 more novice questions. What is the purpose of the Swirl motor exactly and what are those 6 flaps?

merlin can tell you better but the swirl motor aids efficient combustion. The flaps are part of it.

Each cylinder incorporates one swirl port and one charge port. The swirl ports can be closed by the swirl flaps (seen in my pics) In the lower engine speed and load range, the swirl flaps are closed by the swirl valve actuator. The entire air mass flows through the charge ports only, which results in greater swirling (hence the name). The increased swirling produces uniform combustion for better engine performance and reduction of particulates. As rotational speed and load increases, the swirl valves open, so that optimal swirling and the required air mass are provided for the current operating conditions.
