This has been discussed alot on internet forums already.
Don't use an OCC with a breather. Keep it as a sealed system. Let the intake pull out the vapors, the OCC filter out the oil in the vapor, and route back the air into the intake manifold. With breather OCCs will tend to make your engine spew out more oil than normal, that is not good.
Also, it's a gamble to use cheap OCCs. A good OCC has baffles inside to filter out the oil in the vapor properly. Cheap OCCs do not have baffles inside. Provent and HPD are good brands.
Yep, it should be a closed system.
Otherwise, there will be a vaccuum effect thus resulting spewing out more oil as aaronix mentioned, even running a few kms, Other posters who installed the breather are assuming that the DIY modifications they did is a good thing, but in reality it aint. But i wouldnt go for an argument because after all it will be their sole responsibility only and probably based on the article they have researched. I will just reply, it was intended for.. But nvm.. Haha..
Aside, from HPD and Provent. There is also the baffled OCC from Mishimoto. In addition to the baffle system, it has a outlet bronze micro filter, an added assurance for the vapor before going back to the intake manifold, it will seive the oil.

Whew.. anung occ ang recommend nyo na brand.. kasi ung provent. Hpd ay sobrang hirap iorder and mahal... ang daming occ sa online like d1 spec. Cusco. Greedy. Pero ang alam ko sa mga ito ay mga walang breather which is good i think pero mga wala ding filter sa loob or baffle... which is recommended na dpat ay meron.... if i will buy one of this cheap icc. I need to modify it pa.
Eto na. Modification na alam ko. Pakitama po kasi di ko alam kung tama.. mag add ako ng copper tube sa line from pcv. Copper tube can be 3 inches basta lower xa sa baffle or steel wool na ilalagay sa loob. (Dpat po ba talga mas mababa sa steel wool?) baka pwedeng punuin ko na lang ng steel wool ung loob ng can. Hahahaha.
Check this link. $20 Ebay Catch Can Made Better. DIY.
Kaya lang.. kesa gumawa ka pa nyan / save you from the hassle... bili ka na lang HPD or Provent. ;)
Noted. So thats what it does.
Why does it have to be copper tube? Would a 4mm silicone fuel line would suffice? Would it be possible also without the tube?
And regarding the mesh, i've seen someone shared on mux tip page that it get rusted and replaced it with a nylon one. Would that be fine also?
But then again, if its works, all the best and cheers [emoji6]

Not sure about the whole reason behind copper tubes, I guess as long as it can withstand engine oil pressure and temp, you're good to use a silicone hose.
Some sellers of occ recommend that metal mesh, for other sellers it come as free (try speedtech) the principle maybe similar to filters of hpd and provent, you have to ensure oil is trapped in the can.
my worry about using nylon is the same re hose, if it can resist temp and pressure, otherwise u don't want parts of it getting into ur intake air.

That's make you wonder, why do some cans are more expensive than others. Its probably engineering, research and development cost and possibly quality.
There are four cans in the market that are costly, HPD, Provent, Mishimoto and Blackworks Racing. What i have is a HPD, and would install this by mid next month returning to my roots for a quick break.
I hope I wouldnt get a reply like im willing to pay extra and etc., could still remember the first time and probably the last time i post on TIP.. Because it goes way out of hand. I just said for those who arent "confident" enough.. Then alot of people showed up, and commented bizarre things like i should have watch some videos and etc., it isnt like i didnt know how to do it, but the thing is nvm. Shut up na lang ako. Hihi.
