2009 Toyota Matrix Mysterious Oil Leak
My 2009 Matrix is leaking a decent amount of oil. It seems to drip from underneath the radiator to the ground. But the entire under side of the engine is wet, and the passenger side axel and wheel well too.
I heard that timing chain tensioner is a common place to leak, also it makes a rattle on startup for 1 second. Can this all be related? Any thoughts?
Your rattle on startup is the dreaded VVTi rattle.
Video is for a corolla, but it should help understand what's going on.
You need a leak dye test to pinpoint the leak. Your timing chain is making noise and needs replacement. Replacing the timing chain kit and new timing cover gaskets will probably solve both problems.
Figured it out. The leak is actually transmission fluid. Coming from the metal cooler lines that bolt onto the radiator.
