Can you run with the PCV valve disconected...and run two breathers instead? I wanted to try and see if i can elimate the smoking i tink im building to much vac in the motor..Also i bet iy would be a good idea to put in the right plugs and the right gap too...Right now im running a 24 autolite gapped at .034 thinking i was putting a blower on the car but i changed my mind so i should go back to 25's gapped at .044 ? do you think im running too rich and its not oil at all if i was burning that much oil wouldnt the plugs be fouled by now? thanks for any help.....

Figure out what's wrong and fix it. Absent that, a separator or catch can might be enough of a band aid for you till you can figure it out.

The 24's should be ok if you dont want to buy 25's (I'd recommend using 25's however).

I'd open the gap up to atleast 0.045".

Thanks The car never ever never ever smoked until i did the exhaust system...I dont have an air pump anymore either so im not pumping air into the heads or exhaust so the motor is really close up now so im guessing maybe thats why it smokes a little at idle and when you first take off...it doesnt smoke after that just at idle for little and when you take off a little puff...but like i said it never did this before the the whole exhaust install...

The exhaust swap should not have had any meaningful effect on the crankcase evacuation situation.

Does the smoke come out of the area around the PCV valve, out the tailpipes or from the middle of the car?

Are you sure it's oil burning?

I have no polution stuff anymore not cats nothing everything is gone almost every vac line is plugged or gone so im creating a strong VAC somewhere ..it comes out of the exhaust only i think its oil..its blueish color....It might be runing a little rich too but i can fix that yet i have to put in an Air fuel gauge but if im smoking a little im sure i wount get a good reading....so thats why im asking is there a way to reduce the vac a little to stop it from sucking thru the carb?
