Smoke coming out of valve cover breather
 

Ok obviously this can't be good, there is smoke coming out of my valve cover breather... The smoke does not feel hot, and some oil vapers are also coming out as I can feel the oil on my finger if I place it over the hole.

What is causing this?

its called blow by, start with a compression test.This is general disscussion so your in the wrong spot genius, You still have a huge forehead.

yep, blow by time for some fresh rings. maybe a crank case vaccume pump if you want your rings to last longer

What exactly is blow by?

Re: Smoke coming out of valve cover breather
 

pressure blowing oil past your rings into the combustion chamber.

---- me, is there anything I can use to at least hide this while I try to trade in my car?

I've noticed also that the blow by goes away after the car gets warmed up...

use thick ass oil. that should keep it from blowing by. the smoke doesnt stop after the cars warm you just cant see it anymore:) and i doubt he has broken rings just worn ringlands.

and blow by comes from the piston compressing on the upstroke and the presure getting past the rings and presurizing the crank case

^^^^^what he said

use 20w-50 helps, engine will make less noise and runs smoother as well.

this has been covered in the tech section before, and now that the search function works we should use it. I have massive blow-by on my b16 thanks to endless NA 8k rpm rips everytime I drove the car. my breather shoots oil out and smokes like a son of a bitch, so what did I do about all this? I turboed it.
