Sorry I thought I posted this earlier perhaps I made a mistake what are your views on putting a catch can my Skoda mark 3 3 which is only got 900 miles on it at the present moment but I intend to keep it at least 12 years obviously I would buy a top end kid so I wouldn't have any problems with with pressure and it would catch all the fumes properly thanks guys

Had one fitted on my mk2 TFSi VRS and although it caught the majority of oil vapour. People were still finding that the valves were gumming up, albeit at a slower rate. Mine also ran slightly rough with it fitted and it was fitted correctly aswell. 

If keeping for 12 years you would probably do better by saving money each month and whenever the issue arrises, getting the head removed and cleaned again.

My uninformed opinion is that if these things really worked as well as some claim then at least one of the manufacturers would fit them as standard.

I do not know of any case where they do but happy to be corrected.

Several owners thought a catch can would be the "cure" for the 'alleged carbon problem' on my previous car (Audi B7 RS4) but all were disappointed with how little oil appeared in the catch can. BTW I say 'alleged carbon problem' because in all cases that reported back to owners websites the loss of power was traced to vacuum leaks, and when I sold mine after 10 years with 88,000 miles on the clock it had just been on a respected dyno and was still making over manufacturers spec bhp.

Couple of examples here from 15+ year old Skodas:

Item 9 here: https://skoda.7zap.com/en/cz/fabia/fab/2005-453/1/103-103004/

Item 19 here: https://skoda.7zap.com/en/cz/fabia/fab/2003-225/1/103-103007/

 

Find it hard to imagine that more recent engines don't have equivalent separators.

Thank you for that, I always expected there was some sort of oil separator system for the crankcase emissions but my comments were with regard to the supplementary catch can systems the OP was asking about.

As an aside I have learnt something as I did not know a 3 cylinder 1.2L VAG engine was fitted to a Fabia (or even existed).

 

I've seen images of high mileage engine internals with little or no build up so is the problem related to lots of cold starts/short journeys?
