hi all I know this has been discussed before but I cant find any info or pictures on how to plumb this in

ive got a 2 port oil catch can its fitted in place of were the aircon once sat but I cant for the life of me work out how to plumb it in

I have a w reg classic impreza facelift my00

please can someone shed some light as to were the pipes connect to the engine as im totally stumped and not really mechanically minded and certainly don't want to damage anything

alan_turbo2000

this is where its located does anyone know which pipe I need to inlet








I understand I need to put a breather filter on 1 side of the catch can to vent but I don't understand were I need to get the pipe from to go to the inlet side

please help me lol

foxy scoob

Someone with more knowledge will be along soon...

But i read you need 3 ports on subaru for proper effect...

alan_turbo2000

There are three breathers on your car. One from each rocker and one from the crank case.
You can use your current can by using 'Tees' to join the three breathers together and then plumb into the can. The other port on the can needs a little filter putting on.

I used two 2 port cans on my car. One can was for the drivers side rocker and crank case and the other can for the other rocker. Not really nessasary but it filled the gap up nicely.

and will that work 100% and not cause any vacuum leaks ?

I did read that full thread

please forgive me im in no way mechanically minded and 1 were is the breather pipe from crank case I belive the 1's from rockers are coming straight out the top centre of the rocker covers themselves ? is that correct

also what size t-piece do I need and I will need 2 is that right ?

alan_turbo2000

sweet mate were is the crank case breather pipe please and is the rocker 1s the 1s coming from top centre of rocker covers ?

Look down into the engine between the inlet hose anf the throttle body and it is in between the two

alan_turbo2000

sorry inlet hose ? I know the throttle body lol

JonMc

This should help...

alan_turbo2000

thank you im such an idiot lol

JonMc

We all started somewhere

alan_turbo2000

true do I now need 2 10mm t pieces then mate ?

or is there a t there joining the cam breathers to the crank breather ?

also do I need to plug anything on the inlet ?

JonMc

iTrader: (51)

You'll need to plug the holes in the inlet where the current breathers go otherwise you'll have an airleak - it's 2 I believe on classics.

Also I presume it's 2 t-pieces but I've got a newage so it may be different:

tee the rockers together and the the outlet from that tee'd to the crank breather and then fed to the catch can

alan_turbo2000

cheers buddy what do I plug them with ?any ideas and were I will get them

JonMc

iTrader: (51)

depends how big the holes are - either buy bungs off ebay or from http://www.apmotorstore.co.uk/ or just use bolts

alan_turbo2000

im assuminf they will be on the plastic part that goes to the air filter and that is were the hoses originally go to ?

JonMc

iTrader: (51)

Yep, just trace the hoses back

alan_turbo2000

cool thank you for all the help

alan_turbo2000

right guys I took a good look round engine today and think I found what I need

is these the 3 breathers ?






the 1 on the right comes from top of cam cover under manifold through to front across behind alternator and in side of inlet plastic pipe

left comes from top of cam cover up across and in to 1 of the pipes behind manifold

rear guessing crankcase breather comes up from behind the engine in to the other pipe with the left cam 1 facing each other

are these them ??

xcore

Can anyone tell me what the gains are from a catch can?

JonMc

iTrader: (51)

The crank one looks about right but I'm not sure on the others as they may be different on a newage and I don't recognise the classic ones

Rather than venting the oil fumes back into the inlet and thereby contaminating the fuel/air mix, you vent it to a catch can that collects the vapours for you to safely dispose of

alan_turbo2000

the other 2 come straight out the top of each cam cover so im guessing there right ? surely lol
