I was recently asked about the baffles in the 455 valve cover.
I have posted a picture to the GMCmhphotos.com site.

Many secondary market valve covers (such as the chromed ones) do not have the correct baffles.
The wrong baffle often will allow a lot of oil to be pulled up the PCV valve and into the carb and be burned out go out the exhaust.
This results in high oil usage of the engine.

DO NOT replace the valve covers unless they have this baffle.
