peter433 Posted April 12, 2013 Share Posted April 12, 2013 Hello everyone I'm new to the forum, I joined to see about getting some information. I have a 1.6 Petrol Mk1 Focus with a Zetec SE engine and I would like to fit an oil catch can but I have no idea where to connect it? I think it goes after my PCV then connects onto the pipes that go back in the engine ? I'm really confused with this as I think I also have a Breather filter somewhere as well. I originall thought it would connect in between this pipe: Any help would be greatly appreciated. Cheers Quote Link to comment Share on other sites More sharing options...
wase16ll Posted April 12, 2013 Share Posted April 12, 2013 think the set up on this is a baffle type breather capsule, bolted on front of engine under inlet manifold, pcv fits into capsule with a pipe coming off to a three way connector, with two pipes connecting to inlet manifold...no other filter fitted first question if its a stock engine, why do you actually want/need to have a catch can pipe you have arrowed, does that connect to bottom of air filter box Quote Link to comment Share on other sites More sharing options...
peter433 Posted April 12, 2013 Author Share Posted April 12, 2013 Hi and thanks for a response, I really just want to add it to see if it actually makes a difference and yes the engine is a stock engine. So do you know what configuration I would use to install the catch can ? I have found a pic that might be relevant: I am looking to just replace the PCV valve but cant seem to find it online.

wase16ll Posted April 12, 2013 Share Posted April 12, 2013 if running a stock engine, fitting a catch can will have very little, if any, benefit. interfering with pcv set up will cause you far more problems unless you use filters, in a sealed set up, without elongating the pipe system....in other words, you will need to come up with a complex system, yet not gain any benefit. if oxygen sensors pick up any amount of unregulated air, will cause idling/mixture problems. only time you would benefit from a catch can, is if you fit a turbo, as pcv system will also need redesigning. pcv would be better sourced from Ford, they are reasonably cheap, plus know you will get correct one as number of pcv look same/similar, but are actually different 1 Quote Link to comment Share on other sites More sharing options...
artscot79 Posted April 13, 2013 Share Posted April 13, 2013 Pcv is a ford only item the system is designed to send the gas back through the air intake to be burned off a catch can will make the car worse as its all a closed loop system using sensors etc replace the pcv and leave it alone you wont get any gains from touching it just a rough running engine Quote Link to comment Share on other sites More sharing options...
