Most people weld an AN fitting to the front cover, similar to what RX-Heven did (except he drill/tapped his) for his catch can vent setup.

I don't remember offhand... I think it was 38mm bolt hole spacing with m6 bolt holes.

Just weld the fitting to the front cover. You want the drain as short and straight down as possible.

That flange is a little bulky. If it doesn't fit you can probably machine down the corners a bit. ATP turbo has one that is a little lower profile.

No worries let me know when you are ready.

Do you know if this is a -6 or -8 fitting? I would like to do this for my catch can in the future.

you want -10an as a minimum!!

with out doing it properly and removing motor and sump / front cover.. if you could get away with removing sump whilst in car then you could drill the front cover and use a bulk head -10an fitting
