Stock catch can/breather
I have seen a few threads about the nipples on these things breaking off, etc. Is there any reason why you would not consider replacing the stock catch can with one of the aftermarket ones?

Very well the PCV air/oil separator, which effectively seems to function like a "catch can"

Is there an air/oil separator? I have not heard that our cars have one. There is just a short tube that goes from the crank case to the intake as far as I know anyway. This is why some people add a catch can.

its junk in that regard. it will still let a lot of oil and who knows what else into the air intake. i broke one of the fittings off mine and ordered an aftermarket catch can to replace it. take a look for yourself on your car. remove the tb and check it out. even 100% stock, mine had oil dripping off of it.

There is a separate PCV hose running from the block to the intake manifold. The PCV hose is the on “dirty-side” and draws the contaminated fumes (oil, fuel, and moisture) from the engine into the intake manifold. This is where you would install an aftermarket catch can if you want one. |

Blackheart, if you have warranty left on your Camaro I wouldn’t put a catchcan on the engine as the warranty will be void if you do.
