Breather hose issues

Hi,

So in an attempt to swap out the hoses, the old one broke and sent a few pieces into the hole where it plugs into (in the valve cover).

I played Operation and got all the pieces out, but now the question is, how does the new one go in? I don't want to break another one. Do I just force it in? I thought it should snap in but it seems like it might take some force to get it in.

Also, is it safe to drive with it disconnected for a day or two? It'll probably just make a little mess, right?

Sorry if this isn't very clear, I am flustered and in a hurry. Girlfriend wants a ride home later on

Haha, she isn't here, she's seeing a movie for class. Lucky me though, she just texted me and said she was going to walk home

The new one should go in easily as it will be nice and soft.

This thread is dangerous. The whole time I was trying to explain the problem, I kept coming across innuendos

Anyway, I still cannot get it in, although with the grommet connected to the holder, it sits atop the valve cover pretty tightly. I'm thinking that I'll get the engine warmed up and maybe then the plastic will be a little bit softer.

I just switched to the single piece flat style (highly recommended) and mine had a spring clamp on the valve cover side. I just used my needle nose pliers to open it and it slid right over.

Where did you get that? I haven't seen any hoses other than the stock kind.

If you run without it, put something on the hole in the air cleaner cover, IIRC the blowby doesn't go through the filter

That is correct. The blow by gets directed into the air flow with out filtration.

I got mine used from SoCal Mercedes Parts (Phil hooked me up with them a few months ago). It was cheap, a MB part, and one piece as opposed to 3. I had seen many pictures of them on this site and decided that was the best option.

After closer examination, I think I found the problem - the grommet thing that the hose plugs into on the valve cover seems to be warped, but just enough to keep the hose from plugging in, in addition to very, very hard. Looks like I'll have to break that out, too, and put in a new one. The reason I overlooked this / didn't buy a new one was because on ***************, they had a grommet but the picture was (or at least seemed to be) incorrect, so I thought it was something else! Silly me. Thanks for all your help though. And, if you ever see yourself having to change the hose, be prepared to have it break on you!

Maybe is the same

I recently changed my breather hose on a 1992 300D turbo and when I ordered it I was lucky because the guy ask me if I want the rubber o-ring also so I said yes. Who ever had the car before me run a regular rubber hose (which was held in place by electric tape from the vacuum hose) from the valve cover to the intake hose, so I did not know how the original looked like. After a few days I got a MB original plastic hose that is raped in a soft rubber and the o-ring. So I just inserted the rubber o-ring in the valve cover and after that I put some oil on the plastic hose end and I locked it in. Easy and painless and now my valve cover is oil free.

When I search FastLane for the flat style, I don't see it. Did you buy yours from FastLane? PM me if you didn't.

Thanks.

Yep, that is what I need. I guess since mine is so hard, I thought it was hard plastic originally and wasn't meant to be replaced. I have the same hose you mentioned, with the foam around it. My old one had a garden hose on the top half...not sure why they bothered with that, but it didn't look right! Haha
