Greetings to all! Second day working on my valve cover gasket leak and I snapped one of the breather hoses right before the tip and cracked another. I'm an idiot I know lol. Anyways just trying to see if you guys know where I can find a new set of these for the drivers side? I have the part number for one but couldn't find the other (part number A1120180182). Any help with the second one or at set at a decent price would be great. Maybe Rob would be able to help but I'm not sure. Thanks in advance!

 

Speaking of Advance, go there or Autozone and get some regular hose of the 2 sizes, that's what is on my car for a few years now.

 

That's usually what I do but wanted the trusted advice of this forum. I'm pretty new to fixing my own car and I'm doing pretty good so far because I'm a figure it out kind of guy. I just wasn't sure if this would be something you could get from down the street. Anyway, thanks a lot.

 

Here's what I got from the 04 parts manual.
Hose (right vent) 05097789AA
Hose (left vent) 05097787AA
Hose, small (left vent) 05097790AA
Hope that helps, there is Mercedes parts cross reference guide in the documentation collection, if you look there, you may get lucky an find those numbers cross.

Edit ; by George ,I think you got it!

 

Also, if you install the NeedsWings oil catch can you use the hose Rob sends in the kit, it is just standard heater hose.
The big hose from the driver's side vent to the intake before the throttle body is also standard, just a slightly larger size. I have screw type clamps on mine, not sure they are needed though.

Speaking of the catch can kit, many probably still have the old hoses from installing it.
I'd give you my old ones, but they were so stiff and cracked that I threw them away.

 

Thanks again you guys are always a huge help. My crossfire is my most prized possession besides my wife haha so I want to be sure I'm taking the best care of it.

 

Check out Pelican Parts. All the Crankcase Breather hoses are listed for the 2004 M-B 320SLK (same car as the Crossfire). Over time, nearly all the vacuum hoses around the engine will "dry-up" from heat exposure. Any attempt to remove usually causes it to crack and/or split.

Pelican Parts Crankcase Breather Hoses

 

I completed the job today and we are good to go. There's still a couple of other things I have to work on later down the road I.e tune up time but I'm content for the moment. Also, I grabbed a hose from Advance AP (didn't even need the clamps or exact part) they fit perfectly over the connectors to the covers.

 

Those who suggested or used Advanced or AZ hoses if you wouldn't mind shooting me the link for the ones you used that would be great ... have both to replace on my 05 limited coupe and I may just try to do this if it's easy enough.

 

This is the hose I bought. You'll need the regular size and there's a slightly bigger one you'll need too. Also ensure to buy claps.

I checked the Mopar/Mercedes cross-reference part document......And those Mopar parts don't even exist there.....

 

Look at my post (#7) in this thread. Pelican Parts lists all the crankcase ventilation hoses for the 2004 M-B SLK-320. These will fit all Crossfires.

 

Pelican Parts is a good source for Mercedes part numbers.
Anyone who has fitted the catch can has removed these parts and may still have them.
