I just threw this catch can together with some 2" abs pipe and fittings from home depot for about $30. The hose was previously hanging down just past my front sway bar so it didn't get any oil on the engine or rad but it would still drip on my driveway and gunk up my steering linkage, front axle, underside of the engine and I had a habit of hitting my forehead on it whenever I would climb under the front of my truck...so I decided to make a canister to contain the oil but still let the gasses out. It has a chunk of steel wool in front of the outlet to act as a filter and a brass drain fitting on the bottom. Inlet and outlet are 3/4 ID hose and it is zip tied securely to my sway bar and steering box brace. I'll get some better pics of it later...

Remember there is a chunk of hose on the original breather. Mine looked good after 15 years. Your right, you just have to use the correct hose.JR

Using hose should be no issue when it comes to inner degrading of material. Hoses now days are made of gas and oil resistance material. That would take many many years to do and would be from age and temperature changes. I would think that the softness of the hose would sag in places collecting slight puddles of oil over time and possibly restriction of vapor flow, (if this might cause a problem). But that can be a non issue if layer out and supported right.

All of this is true. I am just a little biased to my mod set up I suppose. I would be worried about it kinking or something but as long as you set it up right you shouldn't have an issue. I guess the whole point is do whatever you have to to get the oil away from the front of the engine and radiator.
