Well guys I have removed the plugged
oil filler cap one the right valve cover and replaced it with a filtered breather. I have removed the for racing vent from the left side valve cover and installed a PCV valve tubed back to the intake manifold port that was capped.
Now time will tell if it works as I clean up my engine for the last time (hopefully)
Many thanks for all of the hints and suggestions, all were appreciated.
