Crankcase tube/hose

I ended up, replacing things with a combination of aftermarket hoses and stock oem parts on my 1.8T.




I found the Gates hose to be made in USA; excellent quality and has a lifetime warranty.

I bought the elbow from FCPEURO with a lifetime warranty; got a oem part, a oem pcv valve and then, the "T" I went with a improved silicone hose, part I got from 034 Motorsports, which also makes a kit, that replaces the metal hose and the elbow with metal billet parts (base, pcv), a whole silicone hose replacement kit, for the full length of the pcv system.

I found out later, that a UK based company; makes a billet base and uses a brass angle hose, to create a bulletproof option, to the failure prone stock part.

Other companies, make the billet adapter and the brass elbow, maybe a part you could get from your local hardware store in the plumbing dept? Some are just threaded and others are setup for AN fittings, to connect hoses to do a oil breather/catch can setup.

Well i don't modify my engine. If carbon buildup is the problem maybe folks can run Seafoam through it's intake and that cleans up the manifold & valves pretty good i do mine annually. You just disconnect the small hose on top of the throttle valve and hookup a clear poly tube and with vacuum the cars sucks in the Seafoam a little at a time, just do about 4-6 ounces.
