The Infamous 2AZ-FE 2.4L Engine
In an earlier article we learned about why some Toyotas burn so much oil with an example given discussing the problems with the 2AZ-FE 2.4L engine. The problem was due to the use of low-tension piston rings that were designed to decrease the load forces on an engine as the pistons drag against the cylinder walls.
However, this design showed its flaws after the vehicle aged a few years and that low tension turned into serious oil consumption issues due to excessive amounts of oil were eventually able to escape past the rings and into the cylinders.
According to the Car Care Nut in a recent video, the issue had been resolved by Toyota years ago with a new piston and ring fix that took care of the problem. However, what if you come across one of those older used Corollas today that has not had the fix?! Can it still be saved today?
