If you're noticing a leaking timing chain cover in your Toyota Corolla, it likely means there's a faulty seal on the cover. Fixing this can be pricey, as you may need to take out the entire engine to reseal the cover on the four-cylinder engine. While timing cover leaks are uncommon due to seals meant to last the vehicle's lifespan, they can be triggered by coolant entering the cover and wearing down the seals.
