Cylinder head grinding is an essential step in automotive maintenance, often overlooked by the general public. We’ll look in detail at the essential aspects of this process, from its importance to its various stages, to provide you with a more in-depth understanding of this technical operation.
What is cylinder head grinding and why is it important?
Cylinder head grinding is a mechanical process that consists of grinding the cylinder head of a car engine to make it perfectly flat and smooth. This operation is part of the cylinder head cylinder head preparation and is necessary when the cylinder head has been deformed.
A deformed cylinder head can lead to a number of problems, including :
- Compression loss resulting in reduced engine power
- Coolant leakage, which can lead to engine overheating
- Oil leakage, which can damage the engine
The most common causes of a warped cylinder head are: engine overheating, overtightening of cylinder head bolts, thermal shock and normal engine wear. Cylinder head surfacing is therefore an important step in restoring an engine’s performance and reliability.
Parameters to be taken into account when facing a cylinder head
When rectifying cylinder heads, it’s important to respect certain tolerances to ensure that the engine runs smoothly.
The cylinder head surface must be perfectly flat to ensure a perfect seal between the cylinder head and the engine block, and sufficiently rough to ensure good adhesion of the cylinder head gasket.
The depth of the combustion chambers must be identical for all cylinders to ensure a uniform compression ratio.
The thickness of the cylinder head gasket is determined by the depth of the grinding pass. If the pass is too deep, the cylinder head gasket will be too thin and unable to seal the cylinder head and engine block.
Be sure to replace the cylinder head gasket with a new, suitable thickness. After rectification, the thickness of the cylinder head gasket must correspond to the protrusion height of the individual pistons.
How much does cylinder head grinding cost?
The cost of cylinder head rectification varies according to a number of factors, including: the type of engine(diesel, petrol, etc.), the extent of the work to be carried out, and the garage or workshop carrying out the work.
In general, the price of cylinder head resurfacing includes disassembly and reassembly of the cylinder head, grinding of the cylinder head surface, replacement of the cylinder head gasket and cylinder head bolts, and checking of the cooling system for leaks.
If the cylinder head is damaged and requires additional repairs, such as welding or valve replacement, the price of rectification may be higher.
It’s also important to make sure that the garage or workshop is qualified and has the equipment and resurfacer needed to grind the cylinder head properly.
