The Telltale Signs That Your Cylinder Head May Be Faulty

Must read

No matter how well you take care of your car, it’s always going to need repairing from time to time. One of the most important parts of your vehicle’s engines is the cylinder head, which makes sure that a channel is created for the coolant to reach the engine block that then cools the engine.

A damaged cylinder head left unrepaired can have devastating effects on your car, and you may end up requiring a complete engine rebuild. Below we’ll go through the warning signs that your cylinder head may be damaged and in need of urgent repairs so that you can avoid this at all costs.

Oil leakage

Oil lubricates the mechanical part of your engine, including the cylinder head. If your cylinder head is cracked this could result in oil leakage, which most often results in a puddle of oil being left under your car while it’s parked.

If the crack in your cylinder head is large enough, the oil may leak into your engine’s internal chambers, which can cause even more damage. If you notice oil spilling out of your car, make sure to have it looked at right away to avoid requiring the entire cylinder-head to be replaced.

Coolant leakage

Coolant is essential for cooling the cylinder head, engine, and more. Just like oil, a cracked cylinder head can cause the coolant to leak and form a puddle underneath a parked car. It can also be spotted by an overheat warning lighting up on your dashboard.

Most of the time, this issue can be resolved with repairs rather than a full engine reconditioning if it’s dealt with quickly.

Weak engine

If your cylinder head is breaking, then your engine may not be able to burn fuel efficiently. This can result in a weak engine and your car not running properly, and you may find yourself having to restart the engine repeatedly.

If your engine’s performance is worse than usual, this is often a sign of more severe damage. If your car has gotten to this point, you must visit an engine head repair expert right away.


A faulty cylinder head can result in your cylinder being put under extreme pressure due to the heat, which can cause the internal components of your engine to overheat. This occurs as the coolant isn’t able to reach the engine, and may start to deform.

You’ll be able to tell that your engine is overheating if your temperature is in the red zone, and this should be dealt with immediately.


Smoke coming from your engine is a sign of extreme and most likely irreversible damage to your cylinder head. This means that exhaust gases have reached directly into the engine space, and represents the last stage of cylinder head damage.

This can be avoided if you stay on the lookout for the warning signs previously mentioned, so make sure you stay alert at all times and have any issues looked at by a professional at the first warning signs.
