PCV catch can install.

[Goldenfrog]

I put a catch can in my 93 Voyager today. I figured why not. I went with a cheap eBay model. While installing it I noticed how poorly my PCV system was setup. It amounted to a PCV valve on a 5-6 inch hose running strait down into the intake.

I replaced the valve, a bunch of hose and changed how the valve was mounted (instead of laying on it's side pointing down it now stands straight up)

I then added the catch can and a clear fuel filter after the can so I can see if it's working.

I must have fixed a vacuum leak in the process because my idle smoothed out. Either that or I was sucking a ton of junk into the intake.

Cool, Id like to know how it ends up working out. Ive thought about making one of those.

I have a catch can on my Firebird. It has a strong tendency to suck oil out the PCV valve which runs straight into the intake manifold. This is especially important on that car since the engine has a CR of 10.4/1, and oil mixing in with the air fuel mixture will lower the octane level. I made mine out of an inline air compressor filter, some fuel line hose and some plumbing fittings.

Have you thought about putting some distilled water in it to see if you pick up some mpgs? If it vaporizes some water, it may help. Just don't add too much.

I'm not sure why I would want to draw water into my intake.
