CLEANED OUT AIR CLEANER NO OIL WAS BEING SUCKED THROUGH IT
NOR WAS IT IN THE LONG HOSE FROM AIR CLEANER TO X-OVER TUBE

IF I REMOVE THE SMALL RUBBER HOSE FROM CARB HORN TO X-OVER TUBE REV UP THE ENGINE I CAN SEE OIL PUSHING OUT INTO THE X-OVER TUBE & PUSHING OUT THE TOP OF THE OIL TUBE ..38 STILL RUNNING FINE NOT SMOKING BLUE OR WHITE
I CAN PUT MY HAND ON THE TOP OF THE OIL TUBE AND FEEL IT HAS PRESSURE PUSHING AND MY HAND IS BLACK WITH OIL..

Check the oil level on the dipstick. If it is over full, you most likely have a bad fuel pump and you should not drive it any longer. Smell the oil, if it smells like gas, stop. You will need to rebuild the pump, drain the oil and filter and change them.

AS I STATED JOHN IT ISNT BUT TAD OVER FULL..OIL DOES NOT SMELL LIKE GAS I EVEN TOOK A LIGHTER AND LITE IT ON THE DIPSTICK TO SEE IF THERE WAS A FAINT FLASH..NOTHING ...

I WILL DRAIN IT TO CORRECT LEVEL WHICH I WILL BET ISNT A PINT TO REMOVE..SOMETHING ELSE IS GOING ON ..I HAVE CHECKED ALL VENT LINES ALSO THIS HAS THE FORDING KIT ON IT BY THE WAY

Check the PCV valve and line to the PCV valve,could be plugged and not taking care of the blow-by and that is the only way that pressure can escape other than blowing a seal. just a thought.

Sounds like you have your fording valves are closed and you are pressurizing the crank case.

FORDING VALVES ARE OPEN AND HAVE BEEN..I JUST TOOK THEM APART TO MAKE SURE THEY ARE CLEAN

Then severe ring wear and blowby are the next choice. But your compressions readings do not seem to indicate that. Were your readings taken with the engine at operating temps and the choke and throttle plates wide open?

Did you remove the vent adapter from the side valve cover and confirm it is not plugged?
