All, I'm sorry, but I think this is getting blown way out of proportion. As an engineering and design company, our goal will always be to continue to test and try to improve our products. We have our early generation Catch Cans in place and performing very well for 12+ years. We even have some of our prototypes still on the road and performing well after 15+ years. Our own shop truck is a 2014 GMC 5.3L Sierra, and the only Catch Can ever installed is our E2 Catch Can, and it performs very well. Have we changed our design to make improvements over the years, absolutely. A little trade secret, but through testing we discovered if we machined some internal grooves into the condensing chamber, it helped to eliminate the oil creeping up the catch can sides. Also, our newer Diffusers have a sharp machined edge because about 3 years ago we determined the oil was less likely to stick to the Diffuser surface with a pronounced edge.
Each of our Catch Cans, the "Standard", "E2", or newer design "E2-X" has unique features that are specific to that generation. Some customers prefer the bottom drain, some customers like the option to completely remove the bottom of the Catch Can for inspection and cleaning, some like the compact smaller size and price of the more economical Standard Catch Can. This is a perfect example of one size does not fit all.
As I've stated before, All three versions are constructed of 6061-T6 aluminum with an anodized finish. All three versions utilize the same corrosion resistant Stainless Steel coalescing media in the coalescing chamber. All three versions do a great job of condensing the oil vapor, trapping, and keeping the oil inside the container.
On another note, if you really don't like the Clean-Side Separator, we would be happy to offer you a refund. We always stand behind everything we design, manufacture, and sell.
