W211 OM642 Turbo Intake

[davidbilyk]

Hey guys,

Started investigating the oil around the turbo intake issue tonight, gently removed the batwing/turbo inlet pipe/shitty brittle pipe thing from the turbo and noticed that it is cracked and a piece has broken off. I’ve managed to gently line everything back up and it’s holding for now......

Questions are....

Has anyone used the silicone T Piece as a fix?

Where can I get a new batwing without having to pimp the kids out to pay for it

If you are referring Y-junction coming in, thats €€€. There are silicon pieces available, see thread om642 plastic turbo intake - any source for JUST the boots?

Even 2nd hand bat wings are expensive.

Did this ever getting fixed? Did the oil stop?
I ask as I have noticed oil around my turbo, on the W211 E320CDi.
I also noticed the pipe was cracked and generally grotty.

The oil mist is normal, the crank vents directly into the turbo intake.just make sure the seal is on good order and not leaking as there is an electrical connection and motor beneath it which can knack up.

You also have the old pcv tube that joins the batwing with the small red seal . A new updated pcv will put less oil mist through to the turbo

It will be new and let less oil mist past , and the orange seal is clamped on to the end for a better seal

I thought my seal was clamped, there a hose clamp where it fits onto the turbo?

That’s not the right breather but you can see the clamp on the orange seal

The main point is that the PCV has a rubber diaphragm that spends its life going through thermal cycles right on top of the engine and dealing with hot oil mist. Eventually the rubber will harden and split and it no longer works effectively. At around 130K mine was split and had gone hard. car ran so much better when I replaced it.

On my car, that part looks to be in good condition. However, the larger joint, from the batwings, isn't so good. The inside of the plastic has a rough patch, the part which clamps to the Turbo has a cracking, etc...

If its too bad , consider the silicon t piece that's available online. You chop off the original end of the batwing and join in the new joint.

Don't suppose you have a handy link, please?

I'm a bit confused, maybe from no sleep, but why is it a T piece?

D'oh, I see now, looking at my photos, for the PCV hose to connect. I had forgotten it fits on there.

How can you tell? - the diaphragm is inside so not visible until you take the PCV off and destroy to get to it. I would argue if it is over 5-8 years old then it is on its way out. Rubber degrades with age, heat and contact with oils
