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.
