MK5 GTI PCV Valve explained and few other choices

[@bogdancostin253]

foarte misto explicat, ai avut ceva probeme de cand ai facut delete-ul?

[@ClaudiuB]

Mersi, dar cred ca mai mult v-am incurcat :)) N-am avut probleme, dar am pus-o pe cea originala la loc. De pe forumurile englezilor cu GTI am ajuns la concluzia ca in timp nu prea e ok pt motor.

@@ClaudiuB Cand am luat masina avea facut pcv delete de la forge, a fost facut la un Garaj awesome gti, uitandu.ma la fel pe forumuri, pe youtube nu am Vazut nicaieri pcv delete nici la masini cu stage 2, 3. Desi mecanicul meu zice ca ar fi ok pcv delete eu am pus supapa pcv la loc. Acum ma mananca sa fac pcv delete inapoi 😂

Hello mate. By removing the stock PCV and use delete plate or catch can, you removing the vacuum function of the engine. Is that ok for the engine? Is there any reason that the stock PCV before the boost is using vacuum ? Cheers...

Hi, you don’t remove the « vacuum function of the engine » You just block one way so your gasses and other tiny « remains » will go back into the intake. Some of the people are saying that by blocking it, the pressure inside the chamber increases which is not good for the engine, but I didn’t see any proof of that, even if it’s sounds logical. The oil catch can is the best choice as you don’t block anything, you just mount an intermediate filter which will clean the gasses, kind of, before releasing them on the normal way. In the end, after seeing more debates online, it seems that replacing the old PCV with the updated (OEM) one will do the trick and your engine will run in normal parameters.

@@ClaudiuB Yes the one you have on the video is the latest version i think with the check valve in it! What i mean by saying you removing the vacuum is that with the stock PCV if you try to remove the oil cap when the engine is idling you will notice suction on the cap. By using pcv delete or catch can you will not have that suction any more. The delete and catch can are working exactly the same, the only difference is that the delete doesn't filter the air. What is missing from the delete and the catch can is the valve check that is installed on the stock pcv.

Salut! De ce ai ales sa anulezi pcv valve si ce beneficii ai? P.s. limba engleza ma cam bate🙈😂

Sincer nu am avut un motiv intemeiat, de aceea am si schimbat-o cu cea originala dupa nici un an...
