Hello, iv got a 1995 uk turbo impreza and hav just taken the engine apart for a rebuild (on a budget aswel aaaaa) eniwey in the proces if broken a couple of things, the black breather thing that sits on top of bothe rocer cover and the plastic pipe that gose from these, am i able to replace this plastic pipe (that runs under the inlet) with two breather filters (siting on the black bits on rocer cover)?

hope this makes sence

Hi Mate,
Now that the engine's out why not get rid of all that emissions control rubbish and plumb the rocker covers and crankcase breathers to a catch can + filter? Garden hose is a really cheap option for the rocker covers but you might want to use a bigger bore hose for the crank case one.

...Catch can is worth the money since it keeps the engine bay clean and allows you to keep an eye on cylinder/ring leakage.

hmm good idea, so how would i go about removing it, iv sort of heard of these catch tanks but dont realy know enything about em have you any info and pics?

Have a search on here mate, loads of really good descriptions with pics and diagrams...sorry for lazy response

on my setup I got rid of the carbon canister which made room for the catch can and bracket. After that it was just a case of routing garden hose from the rocker cover vents to the can. B&Q sell Tee connectors for garden hose so I made a 2 into 1 breather feed into the catch can and put a mini filter on the other port to allow it to vent to atmosphere.

The crank case breather is a little more involved since you need to block off the PCV valve that connects the breather hose to the intake manifold (underneath the throttle body). Once that's done you can either use a big bore hose to vent the crank case directly under the car, or you can risk using garden hose and routing it to the catch can with another Tee connector...can a bit dodgy if the garden hose bore is so small it acts as a restrictor!!!

Other odd jobs you'll need to do include sealing up the nipples on the intake pipe and getting rid of all the vacuum pipes/hoses that clutter up the manifold.

Should mention that the catch can is a 'nice to have', so even if you just did the hose routing and vented to filters you'd be still seeing all the benefits of keeping the induction system clean.

nice one mate chhers, so you get rid of the carbon canister aswel, ideal,

When getting rid of the carbon canister, can the hoses to the canister just be plugged?? or do they need to VTA as well?

The canister goes to the pipe on top of your throttle body,and to the smaller of the 3 fuel lines on the left(looking at it) of the inlet manifold. Unplug the smallest hose from the metal pipe by the fuel filter and drop it down the bulkhead. Pull the carbon canister out with hoses(connects to 2 metal pipes behind the power steering pump), the throttle body hose needs blocking off,follow the hose,and pull it off the metal pipe(a bit tricky),and block it with a bolt or somthing.This way it ooks like it should.
