airbox foam breather filter, DIY replacement

[ptandme]

Howdy, from N.C. I thought I'd share some info. A posting on march 29th talked about the breather filter in the air box under the air filter. It was titled K&N air filter install (oil in the foam breather filter and cleaning it). I tried looking it up in the Haynes manual, checking two different chapters. There was nothing about the filter anyware.
So, I took my breather filter out, it was clogged, dry and old. I washed it and it disintegrated. I took the half dissolved filter to two part stores, they said it was a dealer item only.
OK here's the good part. Thinking the air box filter was a lot like the foam air filter in my lawn mower, I went to advance auto and purchased a foam lawnmower replacement filter for 1.80. I used leftover clean motor oil and rubbed it on the outside of the filter housing. Then I rubbed the foam filter against the housing to get a rough measurement. I cut it out with scissors, trimming it to fit snug in the housing. It worked like a charm. I hope this helps.

It isn't a filter (If you notice, it's on the inside of the air filter, so the air there is already filtered) it's to trap oil fumes.
Another method is a "catch can".

here's a thread with pictures:
PTCrew.com - Learn it or Burn it.

He used a filter on the breather side instead of another catch can. More oil comes off the PCV valve than the breather.
The oil going into the intake isn't good, just gums things up.
The pictures are a turbo engine, but it's the same for a non-turbo.

Here are parts:

"Mini General Purpose filter part # CHMP5138 $10.35
from jackssmallengines.com
Its a Campbell Hausfield part.
AdvanceAuto had the hose fittings and 3/8 gas line hose - $1.18/ft - 4' was plenty
