Got a 90 F 350 with 460 using lot's of oil so I have taken it apart and found something kinda odd see if you have an answer. #6 is the culprit piston slid out without any resistance but rings looked good and cyl not bad either maybe tension also burned Ex. valve on same cyl. Right head has even colors and looks good but left head all ex. valves are chalky white.
