Came across a oil consuming corolla
The engine had crazy blow by, beat up rod bearings causing a knock on startup, and burned tons of oil. Overall, the motor was in very very bad shape. I expected metal shavings and lots of other crap in the oil. They got an oill analysis back that read normal, with everything measured at or below averages, except for a higher viscosity from some Lucas that had been added. Recommended to run 5k more on that oil. When tearing it down for rod bearings were thoroughly chewed up.
Is a single UOA unable to determine such wear?
