Hi all you boffins
I'm trying to sort out the pipework for the rebreathing system on my J8S 742 2.1 TD

With ref to the attached photo.

Does number 1 or 2 on the decanter go to the turbo air intake?
The drain on the decanter goes to the oil sump pipe 7. I assume
Number 6 comes from the side of the crankcase. What is the box at the bottom of it? is that the PCV?
Numbers 4 and 5 are from the rocker cover. (One is in the centre of the cover at the top, the other is on the side at the rear)
How do I connect 4,5 and 6?
Where is the PCV?

What is in the decanter? Is there any difference between 1 and 2?

I really would appreciate any help. I have various manuals but none are clear.

Thanks in anticipation.

Usually in the decanter is a wire mesh, this helps cool the oil steam down , .
No, no info talk about my end also...
This mesh over the years blocks up, good idea to take off.
Fill with engine degreaser and allow to soak for 24 hours,
NOT always guaranteed to work, have known strainers ( wire mesh ) block that much, that only a steam bath ( what they use to clean cylinder heads in ) works. ( Dont put this in the Dishwasher, divorce waiting to happen)
But can do no harm to try the degreaser.

Hi Ours2012 thanks for your help I really appreciate it.

Can you tell me where the PCV valve is on my engine? It’s driving me nuts trying to find out.

Cheers

I***8217;ve discovered that a PCV valve isn***8217;t technically necessary for a normally aspirated diesel as the blow back is burnt by the engine. I***8217;m not sure if that***8217;s the case for a turbo diesel? I wonder if installing a PVC valve in my system would do any harm?
