If the intake gasket is not sealed right, and is sucking oil into the #2 port, by spraying carb spray into the valve cover, which is into the crankcase, your idle will increase, as the intake sucks it in through the leaking gasket.

Also, why would there be black residue (oil ?) coming out from the exhaust port at the manifold? Could I be juggling two problems like a faulty exhaust manifold gasket also?

makes sense. Should I let the car reach normal operating temp before doing this? Or can it be done as soon as I start the car ?

I don't think the Elite series valve covers come with baffles. The Edelbrock catalog specifically states that the Signature series does, but there is nothing stating the Elite series does. You have to install breathers into the Elite series.

I'm pretty sure your problem is with the valve covers and lack of breather baffles.

With the black residue coming from the exhaust @ the #2 port, you do have a faulty exhaust gasket also.

It can be done hot, or cold.

Thanks for that info Tom.

So if the passenger side valve cover does not have a baffle, what are my options? Raise the pcv with two o-rings like JMARK suggested ? If I add a breather to the passenger side valve cover, does this mean I'm eliminating the pcv system?

suppose I get home and after removing the header i notice that all 4 exhaust ports are "leaking oil", could I still be on the right track of a possible baffle or intake gasket issue??....

At this moment it's apparent that the exhaust manifold gasket at the #2 port is damaged becuase it's leaking. Wonder what #4,6 and 8 look like.....

If the PCV valve is in the drivers side of the engine, that cover needs a baffle under the hole. You can actually just pull the valve out and shine a flashlight in there and look. If you see the head, there is NO baffle. There "may" be bosses and holes in the cover for an "optional" baffle, if they did not come with one.

The cover that does NOT have the PCV valve does not really need a baffle. It's nice but not required.

in my case, the PCV is on the passenger side. The drivers side valve cover has the air breather.

If you think it might be the rings, with the pcv out watch for oil smoke coming out of the valve cover. This is called blow by.
