Hello...a slight tangent here...
I'm interested in this product as a option to avoid potential boost leaks associated with possible SS diaphragm failure under boost. But the catch can option is what really caught my eye here. I've been wondering about the "best" place to situate a catch can. On my old SVT Focus track slave, I had two oil catch cans. One that was connected where there is a breather tube (not sure what you call that) connected to the valve cover. The other was a tiny little catch bottle connected to the PCV plumbing. The intake cover can (which was much bigger than the PCV catch) really had very little oil ever accumulate, even after track days. The PCV catch was always needing to be drained, especially after track days.
Any thoughts about that a best location for a catch can?
I saw your note about the check valve. Thanks for the comment there.
