Valve cover Breather

I've seen a picture of one in a guy from tamparacing.com's impala ss, just wondering how much of an impact it would make installing one.

Really not necessary unless you've disabled the PCV valve. It's not going to make any power or help cool anything. Some guys just put'em on to look cool. 8)

people use them at shows to dress up the bay but it doesnt add any power. provided you pcv works, like Aaron said.

gotcha, 30 dollars for looks? no thank you

There are some justifications for breathers. When you get to a small pulley, big turbo, nitrous or some other super high volume of air, you can get a lot of ring blow-by under heavy throttle. At these times a breather is required or you start to blow oil seals out.

For most applications the PVC is more than enough and a breather is not needed. If you are running smaller than a 3.0 pulley you might be in the range where a breather becomes appropriate. Every engine is different.

but if your running a 3.0" pulley then you most likely dont have the pcv or egr for that mater.
but thank you for clearing that up Derek. i'm always learnin somethin new

is buy a valve cover breather worth the 35$??

sorry typo

i meant to ask is it worth spending the 35$
i know its not expensive but is it a real benefit?

VC breather is less of a mod and more of a "i changed it bc i had to" item.
If you go I/C and loose the function of the PCV or you have too much crankcase pressure then you need to vent it somehow. a breather does this. will you NOT notice a performance gain on a stock car, not unless your pcv valve is stuck.

Why are you interested in one? If you're driving a street Riv, there's nothing to gain, really.

i was just looking into it.
but i noticed my riv makes a strange noise sometimes and i read on a 3800 site that a few people have just added breather to it and it went away.

and i heard the noise on youtube and it sounds very similar to mine but i shouldnt have to much pressure

im currently on a 3.5" SC pulley

I have one that was used for less than a week and I'll sell it to ya for $20/shipped.

But I agree with everyone in this thread in that it won't give you any performance gains.

LOL... I haven't owned a vehicle that DIDN'T make a strange noise every now and then! Figure out the noise, then how to address it, if need be.

i appreciate it Rick, but from what every ones telling me, i think ill pass thanks tho
