update, I can see about half a teaspoon of oil in the line so seems to be doing its job

Did you put use a one way valve in the line to the intake, to stop the catch can pressurising under boost?

Nope, should I?

I havent seen any change in performance or psi loss on the boost gauge

Not entirely sure if its necessary, a few people have mentioned them though

Got my catch can today while supercheap had 20% off.

Quick tip for anyone else buying one, make sure all the fittings are in the box (can doesn't come fully assembled)

First can I got had no "calibre" written on the side which I was happy about, but only had one of the 10mm hose fittings.

Took it back and had to open 4 boxes before there was a complete one,and going by the sticker on the box they were all from a different batch too.

Pretty sh*t for a product that's also kept in a locked cabinet.

All circuits covered.

Slap welded together a catch can at work friday. Picked up some speedflows and 1 way valve, run some 3/8 hose and now no more horrible oily intake. Win

Looks good HYPEDF6, what type of s/f fitting is that going onto the rocker cover? Is it a snug fit like the ford rubber elbow or just sitting there?

-6 fitting. Borrowed a -6 die and just threaded the rocker cover.

Can anyone confirm if the supercheap 'calibre' catch can will fit in the engine bay near the brake booster on an fg like they do on a b series? It looks to be a fair bit tighter on an fg.
