Yea you got it . as far as the catch can goes .. ( There not the classiest thing out there but out of sight out of mind ) they work fine .I can't say much about emissions or any rules or laws for that matter ,, If they ever caught my bike sticking it's nose out on the street they would chop off both my arms , stab my eyes out and fart in the holes . enough said have a good one everybody .

 

i concur


dude just remove the charcoal can and plug all that stuff up. its so useless. this is what i did to one of my old t2's

simple oil filler neck to oil catch can then your done lol.

 

AusRotary.com • View topic - oil catch can problem

have a read, if its a turbo'd engine it HAS to have a vaccum feed

 

just because one person has a strict opinion on the subject does not make it true. i avoid plumbing it back into the engine to avoid pumping dirty oil back into the engine to be burned, lining the intake with sludgy dirty oil to be injected into the engine on a whim.

it is a bandaid for proper turbo oil pressure tuning or excessive blowby in your old tired worn out should be rebuilt engine.

and the intake piping he claims is a vacuum source is ambient air, it may pull a tiny bit of vacuum if it still has an AFM. a real vacuum source is beyond the throttle body.

crankcase oil vapors aren't nearly as harmful to the environment as unburnt raw fuel, so i don't see a huge problem with it. once you have a catch can installed you will see just what you are pushing into your engine..

 

i didnt really get a for sure answer haha. so is this right?


or should there be vacuum? if it does need vacuum would someone be kind enough to draw a picture for me ha?
does it need a PCV and where in the pic should it be put?
Thanks for the help guys!

 

Or this, and be done with it. Or nothing at all, it doesn't really get messy in there.

 

I don't want to get another long winded thing going here but if I was venting to a can I would run a hose from one of the fittings to the can end of story . If your engine is in fair shape there should be minimal vapor I don't see the reason for a filter keep it easy and simple . most guys don't even have a can they just vent with a hose to under the vehicle ( Not saying this is a good thing either but that is what most do weather they want to admit it or not ) . IMO the filter is a waste of time and money and will do nothing but plug with goo . .. Nothing as far as dust will find it's way up the hose it just doesn't happen . just don't have a loop in the hose that will trap anything .. of course for sure someone will have a different opinion ..

The filter is a vent to atmosphere...without it, the can becomes pressurized and isn't doing it's job.
