Engine Knock and loss of power
2001 Corrola wityh about 170K. Burns some oil, so we just put some in,, maybe two much. (3 quarts). After driving 20 minutes engine knock and power was going quickly.
It now starts right up, but has an engine knock and you get no power from gas pedal.
Did we blow the engine with too much oil? Can it be resolved by draining some oil.
Any help is appreciated
