Engine noise can also occur when the oil is old and has lost its viscosity (ability to lubricate).

What to do if your Toyota Camry is leaking oil?

Oil can leak past these piston rings at sometimes high rates, and that can lead to engine failure if oil levels aren’t monitored closely. While you can fix this problem by replacing the piston rings, it’s cheaper and easier to keep a close eye on oil levels. Checking your oil weekly is the best solution here.
