Breather System smoking? What's wrong here...

[BlownVenom01]

So like i posted about before, my car seems to emit a light wispy smoke at a dead stop out of the hood vents. When I check under the hood, the only place that's emitting any smoke at all is the k&n breathers the previous owner used to replace the PCV system (don't know why). But it still doesn't seem like enough smoke to be noticeable outside the car like it is.

Is it normal for breather filters to smoke like that on a cool day at operating temp? If not, what could be causing that... I just changed the oil not 200 miles ago.

its normal, mine smokes.

enough to be noticeable at a stoplight from inside the car? like is it just the hot oil meeting the cool air making the "smoke?"

Is it smoke or steam vapor?

Either way, yes, my breathers used to smoke as well (I now have a catch can).

i have breathers on my 66 mustang and it smokes a little while driving/idle at stoplight. Also i dont have baffled valve covers, and some of the oil drips down and gets on the header tubes and smokes quite a bit. That maybe happening to you:shrug:

Hmm, no pcv system and it smokes.
I wonder what it could be.

I had a catch can on my Sti that worked pretty well. I'm not sure how to set it up on the cobra though. anybody have pictures of their catch can setup?

honestly it's sporadic. I was just driving it today and after a little bit of romping, i pulled to a light and I might just be paranoid but it seemed like more smoke then a breather system. It's also very noticeable at night with the headlights on coming out by them (i have HIDs), but like i said when i pop the hood it only seems like minimal smoke out of the breather.

Are you sure you don't have a valve cover gasket leaking?

Something else... when I used to run breathers and ran it hard, the oil mist from the breathers would allow a fine film of oil to get down on the header on the passenger side and on the top of the X pipe behind the driver's head.

As far as a catch can: http://www.svtperformance.com/forum...555809-winter-mods-2-catch-can-panel-etc.html

This is the odds.

Cool day will also make it seem worse.

Scroll down you'll see a clean setup in a yellow Cobra. :beer:

I've had the K&N Breathers on both valve covers for a month now with Zero smoke,smell, oil leaks or any other problems, I spray their oil on the gauze and wrap mine with sweatbands!

My breathers smoke sometimes too, but I also just ordered the catch can system. Cant take the oil drippage anymore
