First before you aggravate yourself go out and get these hose barb T's

THE 1/2" is for the driver side
And the 3/8 is for the passenger side


START Driver side first from the valve cover


Take off the male to male black hose barb close to the throttle body and put the T there and the 1/2" hose going to catch can







This is where the other end of the half inch hose will be snaked in through along the brake lines



Make sure to plug the driver side back in


The passenger side now

Your to going have to take off the surge tank to make it easy to work
Remove the black hose from the valve cover connected to the valve cover right beside the surge tank that is where the 3/8 T and the little 1" hose that came with the kit will go.
Use the new 3/8 T and snip one groove off of the tips. On opposite sides only cause it is to long. do not snip anything off the hose going to the catch can.
Put the little 1" long hose into the pass valve cover part then add the T and put the other side (black hose) coming from the under the throttle body.





Then connect the 3/8 hose that they gave you snake it into here you need a dremell to cut a hole make sure to lift the rubber strip to get it out






Make sure to take off the cabin filter box so you can install the hosees from both sides


With the cabin filter back in

 

Very nice!

 

Nice write up!

 

Awesome...I would like to do this one day!

 

thanks for the diy for this.. will def have it handy when i install minejkoi

 

Shiiiet dont look as easy as they made it seem saying it's all plug nd play

 

Thank you all for the complements.

I will help you on fri berti00 to install the catch can if it does not rain

 

Nice write up and pics.
Please don't take this next part the wrong way as my intentions are well intended. By the looks of it, you might need to reconfigure the hose arrangement. I don't have this kit, nor have I installed one, but I would think that by T'ing the lines the way you did, the oil vapors are still not going to collect in the catch can. I could explain further if you want.

Hope I'm helping....and don't shoot the messenger.

Peace.

 

Nice write up!

 

I tried to point out the same thing in his other thread....I guess the kit did not come with great instructions, but the way he has it routed clearly is not correct...

FWIW, I prefer either a two can setup or a can with two in and one out.... DC3s for me

 

^^ what is the correct way of routing it than?

 

I kind of get what your saying Here. So here is the diagram of the stock layout
A to A is where your supposed to T it off from and install the catch can in between the the two A hoses.

but can you please elaborate more? I completely get what your saying about routing each side individually into it own catch can prob would be the best way to really go about it. Is that what your saying right cause it does make more sense.

 

Ty

 

What he is saying make a lot of sense one catch can will catch some vapors but not all you will need one catch can on each side before it enters the throttle body. The setup now is just t'ed off instead of completely cutting it off from the throttle body.

 

From valve cover port A to inlet of catch can (new, non-OEM line), then from outlet of catch can to OEM line A (use a male to male connector to connect the non-OEM line to the factory line). This routing will require you have two cans since the FTB only has one inlet.

OR you can do as follows :

From valve cover As run two new non-OEM lines with an inline check valve and then connect to a T (tee) from the T run a non-Oem line to the catch can inlet. From the catch can outlet run a line to port B on the throttle body. (Just save the factory lines.)

For what it is worth, I would also install an inline filter with line C and see if you get any buildup. If so, then I would add another can or just change the inline filter periodically.

I hope this helps.

 

I think running one catch from each side will be the best way.
Since a check valve in running into two lines might get stuck or not enough flow at WOT

 

^ There ya go, the second arrangement for your setup. Not sure why a check valve would be needed though.

Manuyc, port B is the vacuum port and needs to be plumbed directly to the catch can. The other port on the catch can can be T'd to the valve cover ports. The idea is for all the vapors to be pulled through the catch can. As for which port on the catch can should go where, the port with the filter should go toward the valve covers. The filter will then collect the vapors and drip into the catch can.

 

A PCV is designed for the task, but I agree and prefer two cans. Or a nicely designed can with two inlets.

The nice thing about two cans is you can generally make the setup cleaner (less lines wrapping around the engine). That said, sometimes find a good spot to mount two cans is not an option.

Great write-up BTW, just make sure you edit the pictures and directions, so that folks that follow your post don't install their cans incorrectly.

 

AND

 

All I can say is I was following instruction diagram from kit prior install.
But cij911 you help make it more clear for and I hope it helps anyone else that is going to install a catch can. Cause there isn't one here much info on it for e55

Thank you again

 

Im about to install my new ADD-W1 Catch can but none of these pics are being displayed. It says picture has been moved or removed. Anyone have another DIY with pics? I have my serge tanks off to get powder coated so I figured i get this done before I reinstall them. Any help would be appreciated.

 

Go to the DIY sticky then look at the very last post DIY sticky thread addition, then go into that and you will see many DIYs including a catch can install.https://mbworld.org/forums/w211-amg/...reat-info.html herehttps://mbworld.org/forums/w211-amg/...-addition.html
