where did you bring it?
kidding mate...you plumb one nipple of the catch tank on the y piece which is against the right side of the block under charge pipe, when standing infront of bay.
The Y piece is held onto the block with 1 screw. Note, when you undo that you're also undoing a hose where your collant flows through (i didn;t know that before lol)
then follow that Y piece, where it comes to the front of the block under your inlet.
This is where I would strongly suggest you to take inlet manni off.
ok, so you follow the Y piece (hard plastic pipe btw) until you get to a rubber hose, which T's off. on the one side the plastic pipe will continue, and the other side T's up to the underside of your inlet. If you took inlet off it will be the (i think) the 8mm hose plugged on the nipple of underside of inlet.
So you need the cut/pull the rubber hose out between the 2 plastic pipes.
Then you put a bung in the 8mm hose off bottom of inlet.
Then you're left with 1 straight bit of plastic pipe going to the Y piece, with a gap where you cut the hose away.
Stick a replacing straight bit of hose between that.
Then place a 19mm hose on the other nipple of the catch tank and job done. This hose will vent the oil fumes away, much like sticking a breather on it would
hope this is understandable lol
