Description
What is a cylinder head and how does it fail?
If your car has overheated, check the cylinder head and gasket for
signs of cracking or warping. If the cylinder head has warped even
slightly out a flush state, it will cause cylinder head cracking.
In this case, the head gasket may need to be replaced and the
cylinder head should be ground even again before it cracks.
WHAT IS THE FUNCTION OF A CYLINDER HEAD?
The cylinder head is a critical part of your diesel engine. With
the head gasket and cylinder itself, it creates the combustion
chamber that allows the combustion process to occur properly. It
also lets air in and exhaust out. Coolant and fuel both flow
through your cylinder head, making its health vitally important to
the overall function of your engine.
There are several main symptoms of cylinder head problems—high oil
consumption, bad fuel mileage, and engine overheating to name a
few. You can watch our video for more information.
One of the most common cylinder head issues is cracks caused by
overheating. These cracks often occur between the valves, but not
always.
Sometimes, if your engine has high mileage and the valve stems or
valve guides are worn out, oil can begin to leak down into the
combustion chamber. If your valves aren't sealing properly,
combustion will be affected and you won't get the efficiency you
want in your engine.
Cracks through to your fuel system can allow fuel to infiltrate
your engine oil. This contamination can lead to other major engine
issues.
These problems, if left unaddressed, could mean serious trouble for
your engine, and even result in total engine failure. Often, the
best solution is to replace your cylinder head. You have a few
options when it comes to replacing your cylinder head.
