Those of you that went the ebay route, post some pics of what the can collects after the first thousand miles. I have had numerous customers that went the same route only to find that the can was not catching even half of the oil that is actually going through the PCV line. They have all since switched over to the BT can and were amazed at how much more oil they were collecting with the better built BT unit.
Nothing wrong with trying to save money, but if I am going to spend my money, I want to make sure it is going to good use and getting me the best I can get. If money is tight, then I would just make your own can while you save up for a proper catch can. The ebay cans are cheap for a reason.
The Billet Tech cans are built with top quality material here in the US, have the proper designing to catch every drop of oil that runs through the PCV line, and come with a Ram specific mounting bracket to make for a very simple and fast install. No need to add mesh to the can, replace cheap fittings or hoses, rig up a mounting bracket, hope the mount is secure enough to support the can, etc...
Again, nothing wrong with trying to save a few dollars, but with the BT can being only $135, it is 1 of the cheapest mods available for these trucks. If you were to hold a BT can side by side to most of the cans you see on ebay, you would immediately understand why there is a price difference between the 2.
