it's an oil catch can for crying out loud...lol

As long as it works and looks decent

 

yea but have u seen my engine BAY...

I have standards to keep up

High standards

 

f***ing shit, my post from a couple of hours ago did not post

but anyways, as long as they fit they will work (proably better too, cause being larger, it allow that oil that much longer to seperate from the air

also they would require less frequent draining also

 

look at post 115.... u did post it :-p

 

, thought it was after the hondabond comment from civic

 

just get one. then two T fittings and ur set to go. they dont fill up fast at all.

 

rajca that's cause ur motor is running good.

I have a feeling, how fast they fill up is a good indication of the motor's condition/how hard (the driver is driving it).

so the slower the better :-) IMHO

 

Funny thing u say that. i ran out of oil today on the way home from work
that little light was blinking so i pull over and check teh level. just barely shows on teh dipstick

pour in 3 quarts of oil all good. but the oil is black. never see it that black before in my life in any car that ive worked on (or truck). damn bent valves. still beat the shit out of the car.

 

then no freash air can get into the motor as needed, but yeah mainly just needs one off the back valve cover/pcv and that will proably cut out 98% of the oil or more (front vavle cover one should just be letting in freash air anyways)



kinda, but also can be how crappy of oil you might be using
also how is his motor running good with bent valves

 

no, front one doesnt let fresh air in. works just like the rear one . so, run a hose from the front valve cover to a T then from the rear valve cover to the same T then from that T to the catch can.
then
from the catch can to a T and from that T one hose to the front valve cover and one the the back. all done. does the job of two catch cans. and saves u money

 

actually it won't work correctly, part of the reason for them going to seperate places on the intake (aka one behind the tb, and one before) is to help maintain the circulation of air throughout the engine

 

ones goes right before the tb and one goes into the intake manifold plenum. both do the same


and. same oil vapors in the front plenum as in the rear one so u wont have a problem.

 

i don't get ppl who put only one catch can on tho. my2cents

 

bc u dont need more than one. save the money and spend it somewhere else. i got a small $7 or so breather on my front valve cover and gonna be putting one on my rear valve cover.

 

ummm... front one gets it's air basically from the atmosphere (obviously through the air filter first though)
and the rear has vacuumed applied to it, especially under engine braking (actually any time the TB is partial closed, there is a vacuum applied to it; even at WOT throttle there will be an ever so slight vacuum at it because of the TB causing a slight restriction), also the PCV is basically a check valve with a metered orifice for the correct amount of crankcase vapours for the motor

 

ok so I am going to get one or 2 or ZERO catch cans??

wtf is the BEST

 

One

 

x2, two is kinda pointless

 

ok so then I just do the rear one or what?

what's the "proper" way

 

yes the one with the pcv valve which is the rear one, basically you just reroute the line through the catch can, and route it back to the origional locations and you are done, after you mount the can of course

 

k but why only one side??? (I had to ask)

don't both valve covers put the same amount of oil vapor back into the motor?

 

rubber cork ftw!

 

i hope ur joking

u wouldnt want to plug up the vent. but hey, its ur car do what u want

 

so is anyone going to explain WHY i should only do ONE catch can and not two?

and why I should only do the rear valve cover and not worry about the front cover.??

plz and thank you

 

im still stuck on fixing my inline filter

 

some people actually work here, unlike some people

as said earlier the front vent only supply freash air to the engine, so oil should not be coming out, so the rear one only is needed

just use some rtv sealant already

 

^^ thank you for the clarification

 

^np

 

its a valve cover theirs gonna be oil under it. oil gets hot, than u have oil vapors, those vapors will get sucked into the engine. u need to do something about the front one also.

 

Ive honestly never seen any oil come out of the front VC vent. Only the rear PCV.

 

see civic's \/, by design it should not be coming out of the front vent anyway

thank you

 

Rajca, you have the front VC vented to atmosphere right? Have you noticed any oil in your breather filter? If not, then you definately don't need the catch can on it.

 

havent noticed anything. but than gain. it doesnt have any vacuum to pull the vapors out of the vent and into the engine. i know ppl that run breathers on their engine and have no oil whats so ever come out. and not only on v6. i4 and v8 (race engines)

 

there should not be any vacuum being pulled on that vent anyways (except internally inside the motor), even when connected stockwise, the reason for it being before the tb

 

so when the car is idling or driving or WOT. its not pulling any fumes? bc then the engine wouldnt pull any air if that was the case. unplug the hose that goes from the intake to the valve cover, if u get suction where u unplugged the hose, it pulls some fumes from the valve cover. might not be as much as the rear. but still does


another question, why have a vent on teh front valve cover????? theirs got to be a reason

 

because other wise you would pull FULL manifold vacuum at idle, and probably pull all the seals inward

but also you gotta be able to exchange all the air in the crankcase at some point eventually

and try covering the pcv valve hose with your finger with it idling, will be a good vacuum then, and as said the pcv valve is a metering orifice for the vapors, so the reason for the lower vacuum at the front valve cover, never able to pull full vacuum on it

 

So...having a breather on the front isn't necessary then if it's just sucking in air from the intake.?

I would put a breather on, but then I got an open pipe coming from my shiny intake and I don't like that jazz.

 

now if the pcv happens to get plugged (or just plugged enough), you might get oil out the front vent then, but yeah you should never be getting oil outta of that front vent

and what do you mean by a "open" pipe, it needs to have some type of filter to prevent dirt from going in there (be just like pouring dirt into your oil fill port, just slower though)

 

i mean the open "spot" coming out of my intake pipe.... right?

cause if i just slap a filter onto the valve cover, Ill have the side on the intake with nothing attached... which is goofy if you ask me, plugging an orifice or having too many. just isn't my preference

Don't outbid ME! lol

it'll get messy

 

plug it up with a rubber cap or something.
