I notice everyone that runs the catch cans runs them from the valve cover to the manifold...like this



I am wondering if it would hurt to runs a longer hose to get the catch can out of the way...ie, bolt it to the fender wall or something that looks better...Not a fan of a catch can just "floating" there, attached to nothing...

I have mine attached to the firewall with some Napa hoses running between them. I catch oil just fine.

Mine is attached to a bracket near the shock tower. I could use to clean up the hoses, but I think it's in a decent spot. My separator was way too heavy to float.

nice siggy...thanks...I see you have goodyear hoses...forgive me for not knowing/searching, but one would use fuel lines to avoid hose deteration, correct?

I run long hoses all the way to my Whipple heat shield. No ill effects.

I don't drive much anywho...Have like 5K miles, but know I need to complete this, especially since FI is coming...thanks guys...Anyone feel the need to run one on the other (passenger) side as well?

I think I used those hoses because I had them laying around. I wouldn't worry too much about deterioration. Mostly oil and air running through there. I think it would take a long time for even standard vacuum hose to start having issues. My hose routing isn't ideal, but it worked for the time being. That separator was originally supposed to go on my Dad's 335i, but I stole it before he could use it. Needless to say, it wasn't necessarily designed for our compartment.

Same here and it just hangs but I would like to fix that.

moron question buttt what do thesethings do/ do I have one on my V6/ do I need or should I think about using one?

They capture oil before it has a chance to enter the throttle body. IMHO, anyone with forced induction should have one. If you don't run forced induction, I would inspect your throttle body for oil residue. If it is clean, don't worry about a catch can. If it has noticable oil, then a catch can is cheap insurance.
