But wait, just the fact that there is evidence of some leakage doesn't mean it's no good. He blew on that thing for some period of time, and the total space involved was virtually none, so my guess is that an entire crankcase volume would see next to nothing from a boost event lasting the time it takes to go through a few gears, no?
I am in no rush to do anything with my valve, if that answers your question. It is much better than OEM, and isn't a bad or expensive thing while waiting for a check valve to ship. What little it leaks is probably just due to the tolerances on the plastic. If you are creative I bet it can be fixed.
Aiden drives a lot harder than I do, and breaks more things.

bbundy puts a crank vent in his car to help with blowby blowing oil trying to return in the drains back up and into the head, causing oil to pool and in turn causing it to get sucked out the PCV side port because the drain and air channel hole by the baffle is literally in the back corner, I mean really Mazda? Ya couldn't put a small baffle chamber in the middle and put the port up there? Would avoid half of all of this problem.
There's a raised drain hole in that back corner that's supposedly for crank pressure to return bypassing the oil return; it's offset a quarter inch in my head inboard, about 2" down, I'm guessing to make room for something else in the casting, but otherwise is 1/2" in diameter.
Oh, Aidan. Next time you pull your VC just drill the hole connecting the middle baffle chamber to the exhaust side port. It's only a 1/4" hole that I drilled in small steps up to 29/64" which should be plenty large enough for what's needed to vent.
Im not worried about the drilling. I just don't want to pull my valve cover.
<br />Next engine will probably have all those holes drilled out, and some fat hose on the exhaust side, maybe a slashcut to the downpipe.
