I'm making one out of my charcoal canister. I cut the sucker in half, dumped all the charcoal, I'm going to jb weld it back together. It has two hose fittings on top that perfectly fit my breather and pcv hose, and a small hole in the bottom with plastic lattice work around it that I have a bit of the filter material that was in it ziptied around. I'm going to drill a small hole on the top to drain excess oil, mount it sideways using the stock bracket somehow.
