When an exhaust manifold needs replacing

The exhaust manifold gathers exhaust from the cylinder head's exhaust ports into a single pipe. It's constantly at 600–900 °C and subject to large thermal cycles. Typical exhaust manifold faults are cracks and splits — most common on turbocharged petrol engines and older cast-iron manifolds. Symptoms of a leaking manifold: loud exhaust note (especially when cold), poor engine performance, engine management light from lambda errors and an MOT emissions fail. An exhaust manifold leak is also a safety risk — hot exhaust gas can ignite wiring or carbon monoxide can leak into the cabin.

Why do exhaust manifolds crack?

Exhaust manifold cracking comes from thermal stress. Every warm-up and cool-down causes the manifold to expand and contract, and over years metal fatigue cracks develop. Cast iron manifolds are particularly vulnerable — they're stiffer and don't allow thermal expansion as well as steel manifolds. A single instance of engine overheating can also cause one significant crack. Performance tuning that raises exhaust gas temperatures significantly accelerates manifold wear.
