My wifes 78 came all built up. Comp heads, roller rockers, street cam mild, higher rise intake, Demon carb. Looks beautiful, but no fuel filter or pvc set up. I started noticeing oil droplets on the valve cover, I installed cross flag billet pvc beather and then to botton of carb. (summit) Works great and no more oil on valve cover. MY $.02

Sorry I failed to metion the trans fluid. Yes white smoke in small quanties. Then it goes grey in large quanties. You won't see large quanties for long, the trans will go empty and quit moving, and you won't be watching the smoke. Just cursing.

PCV, very overlooked. But very important.

I'm so glad i came across this thread. I've had a slight black smoke problem and thought i might have an oil control issue. Now I think I'll start tinkering with the carb to get a better fuel mix. Thanks for the insight guys.

That's what I'm seeing to - the black smoke. I'm going to have to get myself a vacuum gauge and see what I can do about adjusting the carb.

id be lost without my vacuum gauge..

a vacuum gauge and hand vac pump are the best things since sliced bread.

I had a 77 NOVA that used to suck it's tranny fluid up through the modulator. Found out when the trans started to slam into gear because of the low fluid level. it was an easy fix and a cheap part.

ive seen this on two cars... both novas.. a 75 and 76..

weird..

Question -

I have the pvc valve in the drivers valve cover and hooked up / connected to the base of the carb. In order to get maximum crank case ventilation, should the other valve cover have a breather? Are two breathers better than one?

I'm sure others have pondered this.....

you should have one breather (on the passenger side preferrably towards rear).. two breathers and you will lose the vaccum effect.. no breather means little or no air flow.

think of it kinda like an attic fan.. if you open a window 5ft away from it.. it wont cool your house.. open one on the other side of the house and it cools the whole thing..

you want to get a flow of fresh air through the engine.. this help sucks out oily fumes. (much like the attic fan helps get rid of the smoke when my wife cooks)

Thanks Ben!

I was on the right track.
