My 1965 engine had a small leak in the front "china wall" area of the intake manifold. Being spoiled by today's new engines with no oil leaks whatsoever, I went after it and decided to replace the stamped valve cover with a cast cover while I was at it (have to remove the valve covers anyway to remove the intake manifold. Removal of the intake manifold on an FE engine involves removal of the push rods. Be careful when replacing the intake gaskets as they look symetrical left ot right, but are not. Similarly, be careful about the carburetor gaskets as the gaskets on either side of the spacer/riser are unique. And be careful to mark the temp sensor wire and the distributor advance wire as they look identical.
I did use the blue urethane instead of the cork for the china wall. It works. But I think I messed up when switching to the Cobra cast valve cover as I am now blowing oil. I believe the cast cover may not have a baffle under the PCV orafice. Does anyone else have a similar issue when changing valve covers?
