You will gain nothing by putting a catch can of your car it will cause running problems as modern engines don't like the oil breather being vented to the atmosphere It will also cause you problems when the car goes for an MOT. If you are that concerned about dirty oil being in your engine the best thing to do is change it more often. 1 Quote Link to comment Share on other sites More sharing options...

As such no effect whatsoever on mot test or any problems either in fact the opposite 2 Quote Link to comment Share on other sites More sharing options...

If you look about on line there is a lot of places selling what is a small box with a filter than vents to the atmosphere. To put one an a road car is a waste of time its the sort of thing used on race cars and thus require more maintenance than what is already there.

catmand00 Posted October 25, 2015 Share Posted October 25, 2015 Even if it vented to atmosphere it wouldn't cause any damage at all!! It would be an mot fail though and potentially/likely vent carbon monoxide into the drivers cabin but no harm to the engine or its running. A decent catch can vents back into the air intake and saves your engine from the sludge. No matter how much you change the oil there will be sludge build up from the oil in the air intake system and that causes inefficiency and potential problems with turbos, intercooler etc etc. There are many a thread on here about the benefits 1 Quote Link to comment Share on other sites More sharing options...

MONDEO TXS 2.2 Posted October 25, 2015 Share Posted October 25, 2015 A catch can is useful on a DW6TED4 diesel . . . & is a waste of time & £ on a 1.0 petrol Fiesta 2 Quote Link to comment Share on other sites More sharing options...
Eatonm112 Posted October 25, 2015 Share Posted October 25, 2015 So whats it going to fail mot on? Lol Emissions as the engine will not idle at the correct Rpm for a start. 1 Quote Link to comment Share on other sites More sharing options...
iantt Posted October 26, 2015 Share Posted October 26, 2015 So why won't it idle correctly with a catch can fitted? 2 Quote Link to comment Share on other sites More sharing options...
Taeasz Posted October 26, 2015 Share Posted October 26, 2015 Why bother mucking about with things that are more likely to cause problems than prevent any? Regular oil and filter changes are the most important factors in extending engine life and if you are worried about oil contamination your time and money would be better spent in carrying these out more frequently. 1 Quote Link to comment Share on other sites More sharing options...
iantt Posted October 26, 2015 Share Posted October 26, 2015 I wouldnt bother myself but certain engines inc petrol ones do actually benefit from a properly fitted non venting catch can. Ive seen evidence from a non ford make. Whether the 1,0 ecoboost is going to suffer the same way , only time will tell, 3 Quote Link to comment Share on other sites More sharing options...
fleamoo Posted October 26, 2015 Share Posted October 26, 2015 I would consider fitting one to any direct injection petrol engine, in view of the inlet valve carbon contamination that seems to be a potential issue with this design. 2 Quote Link to comment Share on other sites More sharing options...

petrus Posted October 27, 2015 Author Share Posted October 27, 2015 hello , In the hose before the turbo , (see attached photo ) there is a element (white originally ) which seems to serve as a filter for oil vapors , with the Km it becomes yellow-brown , so oil enters the admission ! over many kms , it seems obvious that the engine suffer harmful contamination, if it is at the level of the valves and the intercooler , for me oil Catch Can be very useful . 1 Quote Link to comment Share on other sites More sharing options...
petrus Posted November 1, 2015 Author Share Posted November 1, 2015 Hello :) have you mounted , like me , a Mountune High flow secondary induction hose for mk7 1.0 T ecoboost ? YES ? then look inside , you will see the color of the oil deposit , I have induction hose black and yellow inside ! worrying for the rest of the engine : valves , intercooler ... short with an oil catch Can , it's clean .

Staga Posted November 1, 2015 Share Posted November 1, 2015 I fitted an oil catch can on my Touneo Connect 1.0 Ecoboost to keep it clean. Run over 2000km and no problems. 4 Quote Link to comment Share on other sites More sharing options...
Jak1 Posted August 8, 2021 Share Posted August 8, 2021 Anyone fitted a catch can on a fiesta 1L ecoboost? Anyone had any problems with sludge on the inlet valves due to recirculating crankcase breather back into the induction via the PCV? Ive been considering fitting a catch can but scratching my head to find a place to fit it in the Mk8 engine bay. Would appreciate any views, experience on this subject. Cheers.

Eatonm112 Posted August 10, 2021 Share Posted August 10, 2021 OK so it has been a while since I posted my comments above and having read them over again I will admit my facts were not 100%. So why fit a catch can - It will help filter out the oil vapor before its routed back into the intake then burnt and in addition it will reduce the build up of dried up nasty oil within the intake tract (valves ) of your engine thus reducing its efficency due to flow loss. The proper way to do it is to run the breather pipe into an oilmist seperator and then back to the inlet pipework as you need the suction to draw the fumes from the cam cover through the mist seperator and back into the engine to be burnt. Please see pics in links for a proper mist seperator https://photos.app.goo.gl/3uaxZ68rwHd1yZC69 Housing https://photos.app.goo.gl/pgcoM9dw81Uc1KQN9 Element https://photos.app.goo.gl/7KjTzUhw6aR2JbB2A Lid The above part is actually made for the diesel truck industry as gunk build up is a big issue for them due to the many miles those types of vehicles cover. No reason for it not to work on our tiny petrol engines as it is the same issue. The aluminium cans that you see sold as catch cans are a waste of money as most of the time they dont have bugger all inside and worse still they vent to atmosphere which is very bad for the environment and I think is an MOT failier due to venting fumes to atmosphere.

Run over 2000km and no problems. I actually bought one of those catch cans and they are rubbish they just vent out somewhere in the lid. You also should know the 1.0 has two seperate breather circuits the second one goes from the cam cover to the inlet manifold and its this one that is used most of the time during light loads. When the engine inlet manifold goes under boost the one you have changed that feeds upstream of the turbo is then active. Also the fumes are drawn out under vaccum which is why the lines are always connected to the intake manifold or just before the turbo. By disconecting the side that connects to the intake makes for a much less effective system thus leaving the partly burnt gasses from blow by to lessen the life of your engine oil.

billyboy Posted August 10, 2021 Share Posted August 10, 2021 I take the view that if they were any good then the car manufacturers would fit them as standard. 1 Quote Link to comment Share on other sites More sharing options...
RayC333 Posted June 5, 2023 Share Posted June 5, 2023 I've recently dismantled two 1.0 cylinder heads (at approx 75k) and was shocked at how much build up there was on the Intake valves and the ports. Inlet valves/seats were pitted whereas the exhaust valves were in great condition. Also oily in the plastic intake manifold. Have never used a catch can but would consider one now on a newer direct injection car Quote Link to comment Share on other sites More sharing options...
