E350cdi ( c207 ) PCV Engine Bleeder Valve

[cr1do]

Hello everyone,

thought I would ask in here before I will go ahead, I own a MB E350cdi C207 the 265bhp version - I have no EML light on but upon inspection of the engine bay I can see oil moisture around the Engine Bleeder valve PCV - I assume the part number I am after is A6420101791 - has anyone with a similar engine version presumably 642.852 replaced the following if so were there any difficulties as well as seeing that my turbo orange seal is leaking I was planning on going ahead with the DIY link ( Repair Kit Intake Mercedes Benz CDI OM642, £ 26.40 ) - my plastic pipe is broken thus I thought i may as well go for the following repair kit as I have seen it done previously

thoughts ?

Thank you

This is me fitting the newer pipe and other seals.

Ah, so I need to replace it with A6420101891? Let's see how much mercedesofnewcastle sells it for

The turbozentrum repair kit is also discussed in that thread.

You could just fit the modified seal with a normal jubilee clip to the old pcv pipe if your pcv valve is ok, like I think mine is, but still need to buy the old complete assembly to get the seal in the first place.

Check part number by VIN...

Check part number by VIN...

I believe that for my E class, which has the 642.852 engine, that Mercedes haven't updated EPC for the E class, so the VIN check will get you the previous design that has been superseded on all other models.

But having said that, it's only the small rubber seal on the end of the pipe that is different, with the very small 'sucked into the turbo' risk.
