pulled the full load crankcase vent hose off just now with the air tube that connects to the throttle body off. It had oil in it, and you can see where that vent hose hooks up to it that oil has been running out of it into the air tube. My next question is the oil returns must be clogged sending the oil up and out of the crankcase vent hoses, can I manually clean the oil returns in the head when I get the valve covers off or is it something that the head has to be pulled to do? Thanks for all the help
