What causes timing cover leak?
The timing cover has a gasket that allows the cover to be securely attached to the engine block. Over time and due to exposure to heat, dirt, road grime, and more, the gasket can often become cracked or wear out. A broken gasket is not the only reason why oil might be leaking from the timing cover.
What causes timing chain cover to leak?
Why Does It Fail? As with so many other seals in an engine, time and heat are the biggest enemies to a timing cover gasket. Eventually, the gasket begins to dry out and shrink, which causes it to pull away from the surfaces it’s bonded to and slowly opens up the seal that it’s supposed to make.
Is there oil behind the timing chain cover?
