bubbles in the oil system is a serious concern though. Maybe a leaking o-ring on the pick-up tube for the oil pump?. Maybe air trapped in the system after an oil change>?

The oil came from Tractor Supply. The o-ring was replaced about a year ago along with the oil pan. I’ll keep a close eye on it.
I should’ve mentioned that I changed the oil the day before, and didn’t start it until the next day, because the battery cables were out.
