Different strokes for different folks I suppose. Keep you eyes open for an email. I'd be curious to see what you think about the setup.

I've seen a few member on here that have filled their cans in less than 300 miles becuase they did the same thing you did. They welded bungs with out baffles in a spot that was susceptible to splash/pick up.

My car was supercharged with the catch can and its current bung in the valve cover (no baffle). I ran close to 8,000 miles with it that way and let out very minimal amounts of oil from the catch can. Before the catch can, I ran breathers on the valve covers. I knew I had a lot of crankcase pressure because I would find a oily film under my hood near the spot of where my breathers were.

Now I am swapping to a large turbo (don't know how that will effect the crankcase pressure). Again, I like the idea of venting it into the exhaust if its not in excess amounts to burn the oil, smell it burning or come out the tail pipes. Not sure if since my catch can never was full that this won't be the case or not. I wish there were a way to tell without just going forth with the setup. I could keep the catch can, but I know I will be limited on room with the large turbo.

Lol, have you ever heard of emissions? Possible that is the reason it is incorporated into the OEM design

Engine life?Pre emmission diesels ran a million miles plus with draft tubes lol

I too would run a catch can in between the valve cover and the check valve/fitting in the exhaust if I went with this system. The exhaust becomes your source of vacuum, it still doesn't (always) solve the problem with the oil. At low exhaust heat/velocity situations the oil won't burn off quickly enough and could pool and clog up chambered mufflers.

I had welded some extra fittings on my oil pan and was venting the bottom end with vents. My thought was why have blow by having to come up from the bottom end and reduce oil drainage from top end to bottom end
