Signs You Need to Replace Your Cylinder Head
No matter how many miles you’re putting on your car, every engine is due for repairs at some point. One of the most important components of your engine is the cylinder head.
So, if your cylinder head is damaged, and doesn’t get the repairs it needs, it can result in severe damage. This could ultimately ruin your engine, which is a highly expensive part to replace.
So, what symptoms signal the need for cylinder head replacement or repair? Let’s find out below:
Weak engine:
Cylinder heads play a key role in containing and directing the internal combustion of an engine’s cylinders. So, when a cylinder head isn’t working properly, the engine’s efficiency, power, and performance can take a hit.
Coolant leakage:
A cracked cylinder head can cause the coolant to leak. So, if you notice spills coming from the head and cylinder block or the “check engine temperature” warning light switching on, this could signal a bad cylinder head.
Oil leakage:
Just like it happens with the coolant, a crack in the cylinder head can cause oil to leak. Whether you notice oil leaking from underneath your car or the “check oil” icon lighting up, it could be a sign your cylinder head is bad.
Engine misfires:
With a severe crack in your cylinder head, the mixture in the combustion chamber will cause a misfire, meaning the mixture won’t burn as it should. As a result, you might find yourself repeatedly starting your car back up.
White smoke:
When exhaust leaks, this often causes the engine to smoke. Also, leaking oil can come in contact with hot engine components to produce this smoke. This is a rare occurrence.
Overheating:
Cylinder head cracking is a common problem in engines, which can lead to other issues. For example, a cracked cylinder head could go through to your coolant passages. This allows compression gases from the combustion cycle to fill those coolant passages, which displaces the coolant. The result is overheating in certain parts of the cylinder head.
If your vehicle is showing any of these signs, be sure to take it to a mechanic to fix the problem right away. The type of cylinder head service you receive will depend on the severity of the damage to your cylinder head.
However, if the damage to your cylinder head is more severe (i.e., engine misfires, smoking engine, etc.), this often signals that your cylinder head needs replacement as soon as possible. In this case, you’ll have two choices—a rebuilt cylinder head or a remanufactured cylinder head.
