RE: M47N2 320d blocked oil return pipe from breather

[320dtoy]

Howzat Guys,

Need some assistance. My car has been sitting in my garage for a while and decided to service and get back on road. Changed the CCV, but appears to be oil on rocker cover, which I assume is due to some blockage with the breather system. Will a blocked oil return pipe from breather cause this oil seepage on rocker cover and can u identify for me with reference to reoloem diagram where is this oil return pipe from breather...occasionally blue smoke from exhaust...just parked it off until I have a way forward.

I'm a newbie, so all help wld be greatly appreciated...thanks

It is possible your oil separator / CCV was clogged and allowing oil to bypass into the intake manifold where it accumulated and then got sucked into the engine causing all the associated issues including blue smoke.
You might need to clean the intake manifold.

Please post a pic of where exactly the oil was / is
