I think I know what you mean - the pipe at the very bottom of the photo below (just above the oil pump). That is the crankcase breather pipe, that connects to the pipe on the back of the intake cam cover - the pipe that points down towards the sump?

that's the one!

Cool thanks Dave, I got a little confused as I was reading on someone's site about water cooling to the oil pump, and the FSM talks about the oil cooler.....but it's not something I have on my oil pump.

On the basis of Harry and a couple of other people I might not run the 'dattodude' oil catch can setup....got a week or two to decide though.

Yeah mate just drilled a hole in the side of the sump and welded a fitting on. Then welded a small baffle over the hole on the inside of the sump to stop gravity forcing oil back up under hard cornering.
