A ticking or tapping sound that shows up when you start your engine and often fades as it warms up is a classic sign of an exhaust manifold leak. It is a common issue that many Columbia drivers first notice on a cool morning, and while it can sound alarming, understanding it helps you address it before it grows into a bigger problem.

The exhaust manifold bolts directly to your engine and collects the hot gases from each cylinder, funneling them into the rest of the exhaust system. It endures extreme heat cycles, and over time a manifold can crack, or the gasket that seals it to the engine can fail. When that happens, exhaust escapes right at the source, creating that telltale ticking as the leak opens and closes with the heat.

Because the leak is so close to the engine, it can affect sensor readings, hurt performance and fuel economy, and allow fumes to escape where they should not. A cracked manifold left alone tends to get worse, and the heat can eventually warp surrounding components.

As an exhaust specialist, Exhaust Plus in Columbia is well equipped to diagnose a manifold leak, confirm whether the problem is the manifold itself or the gasket, and make the correct repair. We will pinpoint the source rather than guess, so the fix actually lasts. If you have noticed a ticking that changes with engine temperature, do not wait for it to worsen.
