So I set that fliter up to look like it's in line, but blocked the end leading to the throttle body with a plastic cap. Don't cut the original pipe, then you can easily go back to original, just get a small extra piece.
The crankcase breather pipe is hanging loose. It's out of sight and isn't dripping any oil. To block the inlet manifold I used a length of hose, roughly tapered, with a bolt and washer stuck inside using silicon sealer. This is a push fit, and being tapered, can't work its way in. The washer is just to make sure.
