Is it an absolute no no to put a breather on the crankcase ventilation instead of the current system sucking the oil vapors back into the engine?

If you don't care about the environment, the engine is perfectly happy with a breather.

Well I definately care about the environment. I have veg. soot coming out the exhaust and I am thinking about getting the syntetic plantmot oil from the UK. I think my crankcase may be enviro friendly then??? If I am running a synthetic plant based diesel rated oil in the crankcase am I ok?

I can't comment on the oil. It does sound as though the vapors would not be harmful, however.

I'm curious as to how you find a synthetic plant based oil that is diesel rated, however???

Maybe others will have more input.

www.dieselveg.com and search for Plantomot. Check it out! It is quite expensive especially being shipped. I hope I am able to get it through a distributor in the US. I am going to ask Alexander at Elsbett in Germany what he knows about it. It is strongly recomended for veg. oil conversions for Direct injected engines.

It really has some amazing properties. It is not easy for me to believe it myself.

I used a breather in a pinch once, because I switched to a K&N style intake and I was loading my intake with oil to the point that it would barely run sometimes.

I went back to stock and have never been happier with the performance. That intake ended up being about a 200 dollar mistake considering all the money I spent trying to make it work.

Fell off the WVO bandwagon when people started trying to charge $2.50 a gallon for dirty vegetable oil.

Just run a 3/4" hose from the valve cover down to about 6" from the ground. Won't harm anything and the "emissions" are negligible unless you have alot of blowby.

+ 1

And, it keeps the intake squeeky clean too!

I would actually have a problem with the hose setup.
In an healthy engine, those gases are mostly oil vapors that are catched and recycled through the crankcase.
A simple breather hose would result in an exponential oil consumption (actually not consumed but excreted).
You underbody would also be coated in a thin coat of oil permanently (great for rust control, not-that great for any work on the exhaust or rear suspenssion).

A beefy oil catcher is necessary if you are going to vent the valvecover gases.

Yeah, I'd just leave it with the stock set up. These cars are very well disigned from the factory and everything works well in harmony together. I can't think of any cars off the top of my head that have a better reputation for longevity than a Mercedes diesel.

It's true. I didn't even drop mine down, I kept it up top and it made a HORRIBLE mess of my engine..
