The exhaust manifold is exposed to the extremes – it's heating and cooling, which causes constant expansion and contraction. Manifolds can crack over time due to the stress from constant, extreme temperature changes.

How serious is a cracked manifold?

Damage to Surrounding Parts

In some cases, a cracked exhaust manifold can cause damage to other parts in the engine bay. It's no secret that exhaust gases are hot, and when those hot gases leak through a cracked manifold, they can melt wires or even ignite parts made of combustible materials.
