    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...

    My engine crankcase is breathing hard and an exploration reveals this. New ground for me but I'm working on the idea that the breather is blocked and pressure has blown the seal on the right blowing oil out. I assume the breather separates oil and fumes somehow with fumes going into air...

    How do you clean these things out? can they be done in situ or do they need to be removed or can indeed they be cleaned or is it a replace job only. I have been told that this is a the first step to try if you think you have crank pressure Thanks in advance
