A cylinder head is a fundamental component of your engine, withstanding considerable pressure and high temperature, housing other parts of your engine, such as the intake and exhaust valves, combustion chamber and more.


In other words, a cracked head can cause you a major headache.

Cracked cylinder heads are a common engine problem in many of the vehicles we work on at Noordeman Diesel, so we’re experts in cracked head repairs across a range of vehicle types.

The most important thing is to identify that you may have a cracked cylinder head and to get it fixed


This leads us to some of the tell-tale signs that your cylinder head needs some urgent attention. Read on to find out more!




1. What’s That Smell?

Leaks from your engine can be an indicator of a number of problems, from oil to brake fluid.

However, if you detect a strong, almost sweet odor coming from your engine when the car is running, it could be a sign that your cylinder head is cracked.

This slightly odd smell is a combination of coolant, which is normally tightly contained by the cylinder head, burning as it leaks from the cylinder.


2. It’s Getting Hot in Here

Coolant is there to stop your engine from overheating by absorbing the heat generated by your engine. If you’ve ever run out of coolant before, you’ll know just how integral it is to your engine performance.

A crack in your cylinder head may result in the coolant leaking out, which is a strong, strangely sweet odor. If this is the case, there’s a good chance your coolant will run out quickly, causing your engine to overheat.




3. Where There’s Smoke…

They say where’s there’s smoke, there’s fire, but in the case of excessive white or grey smoke coming from your exhaust pipe, the smoke is an indicator of a problem in your cylinder. This smoke is caused by the burning coolant, which has likely leaked from the cracked cylinder head.


4. Poor Performance

If your vehicle has been experiencing some of the above signs, but you have been ignoring them, you may find that your engine loses power and efficiency.

As mentioned above, the cracked head results in leaking coolant, which impacts the spark plugs in your engine. It may also lower the total pressure produced by the cylinder, affecting your engine’s performance.


Bonus Tip: Engine Misfires

Engine misfires may also be directly related to your cracked cylinder head, as the pressure from the cylinder escapes into another, lowering the cylinder pressure and resulting in a rough idling engine.
