Oh dear... That don't look right.
Im a little bummed to see that Lobelly.
Just so I'm not misunderstanding. Are you suspecting valvoline is part the cause for your valve-o-lean?
To my inexperienced eyes it looks like something may not have been quite right (either with the metallurgy, or part, or build,) rather than
oil supply?
I'm happy to be corrected and educated.
Good luck with IDing the cause and the fix.
