Oil problem

There is your problem, need to put in a full valley pan gasket, also make sure that you are using the plate or pcv oil breather under the intake.

Edelbrock Rpm air gap yes it has a baffle and 300 miles

Try blocking the PCV off and see if that solves your problem before you go changing the intake gaskets.

I fought intake vacuum leaks for years with valley pan gaskets, so I went to the fiber gaskets. Then I couldn't keep plugs from fouling, so I decided to use both by cutting the gasket sealing surface off of a valley pan like this:



That last picture is gaskets I made myself out of a roll of gasket material that turned out not so great. I ended up getting the good ones later.

I still got some fouling with the AirGap manifold and provided baffle, so I grabbed some scrap metal I had lying around and made this to go on along with the provided baffle:


Works great now. Plugs look good 1,000 miles later. I was changing plugs every 500 miles before that and cleaning them every couple hundred.

It's what worked for me. I don't know what to tell you. Just sharing a combination of options that could help with oil consumption through the PVC in an engine combination similar to mine. Do you run an AirGap manifold yourself? I didn't have the same issues with stock or Edelbrock Performer manifolds.

One thing worth mentioning is to ensure you have a correct and functioning PCV valve.

And all of this is assuming that your issue is with the PCV system.
