What does a broken manifold sound like?
A leaking exhaust manifold will almost always create a ticking or tapping noise. Often, the sound is more pronounced upon startup when the engine and the manifold are both cold. The noise may diminish or disappear once the engine warms up and the manifold expands, closing off the leak.

What does a blown manifold gasket sound like?
A faulty exhaust manifold gasket will produce an exhaust leak that will sound like a hissing or tapping sound coming from the engine. The sound may be especially pronounced during a cold start or during acceleration.
Is my exhaust manifold cracked?
A cracked manifold will usually make unusual noises of some kind as some of the exhaust gasses are being forced out of the crack instead of out the exhaust. This may be more pronounced when the engine is cold and first started and can be anything from a clicking noise to a more pronounced whistling or whooshing noise.
How do you know if your manifold is bad?
Common signs include the engine constantly overheating, coolant leaking, engine misfires, and a decrease in power, acceleration, and fuel economy.
How do you know if your manifold is leaking?

Reduced Engine Power. A damaged exhaust manifold also often has a negative effect on the performance of your car. ... Inaccurate Oxygen Sensor Readings.
What causes manifold to crack?
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 much does a manifold cost?
Replacing an exhaust manifold can be very expensive. For labor and a new manifold, you can expect to pay around $1000.
Can I drive with an exhaust manifold leak?
Unfortunately the answer is "as long as you live". An exhaust leak can be very dangerous and if you must drive it to get it serviced, open the windows so that you have as much fresh air coming in as possible.
How do I find a cracked manifold?
For engines with tubular manifolds, like most 4.0L engines, the cracks are usually visible with a flashlight. Check the areas where tubes come together. Normally they'll crack right in the valleys on the intersections at or right next to the welds.
What problems can a cracked exhaust manifold cause?
Besides leaks, cracks in the manifold can allow outside air in, which in turn can cause the engine to stall or die. If the crack isn't fixed in a timely fashion, you can also cause major damage to the engine, such as blown head gaskets and overheated heads.
Can a cracked exhaust manifold cause rough idle?
The only way an exhaust leak can cause a rough idle is if the leak was in a place where it could enter the air intake system.
