He had one hooked up. I wasn't keen on seeing smoke rising from the front end of the car while standing at traffic lights. In reality, these intakes stay much cleaner than other diesels I've seen using EGR + CCV.

At my next oil change I'll be switching to a lower vapor pressure/lower NOACK engine oil which will reduce the oily contamination.

Has anyone tried venting the fumes from the CCV to the atmosphere? I mean, block off the nipple where the hose goes to the front of the turbo and vent the fumes to a hose that leads to the bottom of the car or some place? Many like me have done that with the powerstroke diesels with good results.

Yep - I tried that. Only thing was, at stop lights I could smell the crankcase vapors. It was kind of annoying. I put it back to stock and the smell went away. There was also enough vapor to create drips of oil, so you may want to route the hose to a container if you don't want drips on the driveway or garage floor.

On the Powerstroke, I vented it to the exhaust pipe above the axel.

I was wondering about that... but I'd be concerned about exhaust backpressure exceeding the PCV pressure. Even with a check valve in place, this could create excess crankcase pressure - I'm not sure how likely that is, but it's possible.

Depends on how you route the hose. In fact, I have a vacuum since it always draws the CCV smoke out the exhaust. I put a check valve in it and it caused the pressure to back up so I removed it.

Thank you.

I sent this off to webmaster@peachparts.com
however the DIY is huge, and will take a while to post on the wikki.

Have a great day.

I'm going to refresh this o-ring. This is at connection between the pressurized air from the I/C to the EGR valve.

There's a lot of "spatter" from exhaust or oily vapors and one of these connections is leaking. It could be the EGR clamp that's leaking.

Any idea on the part number of that O-ring. I will be doing some preventative maintenance in this area, and will have the IM off, so might as well replace.

Yep, did it on our '99. It works fine.. sometimes you can smell the vapors on my '97 but I've never noticed it in the '99.

That's called an 'elephant hose' in some communities in the diesel world and it works just fine. My Cummins came from the factory like that, it spits crap all over the front diff cover...keeps it nice and rust free

Anyway I had it on my '99 E300 for a long time and it worked just fine. No smell is noticeable if you dont overfill your oil when you change it, and it keeps the black goo out of the engine and on the ground where it belongs. It's a 10 dollar mod and worth every penny IMO.

Sure, I'll post all the P/Ns for the items I've purchased. I'll have to get it tonight as it's at home.

This DIY is already in the Wiki. It was posted there on 3/10/2005. I added the additional comments and pics from uberwgn today though.
