Yes it will.
Stuck or bad PCV valve on the Valve Cover to the carb or throttle body. The other is the EGR valve. Most likely the PCV.
All but a very few rare SD Pontiacs are equipped with the PCV valve located in the valley pan. It would be just ahead of the carb in your car.
It's on the valve cover, look for a hose that goes to the carb and the pcv valve just pushes into the valve cover through a rubber grommet.If this is a Pontiac powered Trans Am the PCV valve will be in the valley pan, just under the intake. Should be in front of the carb.
NO it would not.
If the vacuum hose connected to the PCV valve was disconnected, it would idle poorly if at all, otherwise, no.
Follow the 1/2" to 5/8" black round hose (usually pre-formed to shape) from carb. Will go to PCV valve in the valve cover on engine heads or will be in the intake manifold(which the carb sits on)
in the valve cover left side and hooked to carb
Check your PCV valve, EGR valve, ect. A motor needs ventilation, and for some reason yours is not getting any. PCV valve, stands for Positive Crankcase Ventilation. If plugged, that would certainly cause it to puke oil out, some where, anyway. PCV goes into one of you valve covers, and runs a hose to the back of the intake manifold, probably behind the carb.........Chuck.
below the carb. on the driver side
It hooks up to the vacuum ports on the carb or intake.
It's a fairly straight forward procedure. The PCV valve mounts in the valley pan. Run the hose from the PCV valve to the large vacuum port at the bottom of the carb. That's it.
No
