WK CRD oil leaking near end of intake pipe

It looks like my CRD has the pipe with the orange seal and leaking.

Do I need to do anything else while replacing with the revised intake pipe, or just swap it out?

Orange seal = junk. new black seal = good.
Coming from mist in crankcase= good.

Plunix - the short answer is No, you don't NEED to do anything other than replace the orange seal intake pipe with the new black seal version. I'd suggest cleaning up the oil that's blown past the old orange seal (that's the stuff that can pooch your swirl motor), but that's about it. Some guys do the Elephant Hose mod or a Catch Can to remove/reduce the amount of CCV oil entering the turbo intake; others leave it alone on the theory that Mercedes made the engine with the CCV blowby in mind. Getting into that discussion is a lot like arguing Ford vs Chevy, and there's LOTS of discussion on the forum if you want to read through the various arguments.

A lot of CRD owners also use & recommend the Green Diesel Engineering (GDE) Eco and Hot tunes, as they shut off the EGR valve and swirl motor among other things, thus eliminating the CCV oil blowby into the turbo and the risk of swirl motor failure at source. They also have the nice added benefits of added power (Hp and torque) and better fuel economy. Not cheap, though, which is why some guys go with catch cans, EHM, etc.

The extent of mods you choose to undertake thus becomes a personal choice based on your budget, willingness to turn a wrench and the individual engine characteristics of your CRD (some suffer more CCV blowby than others, etc). Climate can also factor in, as there are reports of owners in northern climates with cold winters having trouble with condensation freezing in their Elephant Hoses.

Of course, if your vehicle is still under any factory warranty, I wouldn't be getting too mod-happy, as Chrysler is still on the hook for at least a portion of any repairs. Not many of us left in that particular boat though.

Canuck, I didnt think the GDE tune did anything in regards to the CCV functionality, just the EGR. Am I wrong?

I do have the GDE Hot Tune as of a few days ago. Just catching up on all the mods I :need: to do in addition to it.

This looks difficult to make without the proper tools. Do you have a DIY write up of how you did this? Thanks.

Sorry - you are correct. The GDE tune shuts off the EGR function, which stops the mist of oil blowby from entering the turbo intake. This is the oil that leaks around the orange seal, drips down and eventually pooches the swirl motor on these engines.

I'm really interested too, did you cut down an existing silicon hose application?

It looks like he might've used the existing pipe and simply added his own rubber pipe where the seal exists. I'm going to buy the revised part instead. My dad has a shop that can get what sounds like 33% cheaper factory parts. I'll pay around 100 vs the 150 asking price (Canadian funds).

I'm sure you're right and as I have been asked for £170 for the new part, a silicone hose mod would be really useful as the basic pipe is fine with just the seal leaking and if that's a standard hose that has been modded it could be a lot cheaper and even looks good!

That looks like the orange seal and plastic hose was cut off with a saw; and then that Lowe's type hose clamped on with some marine hose clamps (NCX 68 75 ?). That is a similar hose to what omlette used on his modified safari snorkle.

That hose is not round, it more oval so I'd be surprised if it didn't leak as the marine hose clamp is round.

One is better off just using the black replacement part.

I actually disconnected my air cleaner tube and cleaned up my orange seal today and tightened it more. It seems to be in good shape, if not slightly heat warped. Ill keep an eye on it for now.
