What is an Engine Cylinder Head

The engine cylinder head is an integral part of any engine. It is bolted onto the engine block and sealed with the cylinder head gasket. This closes the combustion chamber.

Function of an Engine’s Cylinder Head

Sitting on top of the engine’s lower end, the cylinder head function is to provide a clean air/fuel mixture for combustion and exhaust the spent mixture from the combustion chamber. An engine needs to breathe in the fresh air and breathe outspent air. An engine has a cylinder head to ‘breathe.’ It contains air passages, valves, springs, and possibly the camshaft. The camshaft, either through pushrods or directly, manipulates the valves to accomplish this intake and exhaust of the air. There are also oiling passages for the components lubrication and cooling passages to keep things from overheating.

How are Cylinder Heads Made

Engine cylinder heads are cast out of iron or aluminum. Once the cast is made, the cylinder head goes to be machined and cleaned up. Oil and coolant passages are cleared. The intake and exhaust runners are cleaned and cleared, as well as the mating surface and the valve pockets and seats.

Signs of a Defective Cylinder Head

The following signs of problems could indicate a cracked cylinder head, a need

for cylinder head repair, or need for a remanufactured cylinder head:

Loss of engine power
Vehicle overheats or is running hot
Observing oil in the coolant reservoir
Coolant level is frequently low
The odor of coolant when exiting the vehicle
Oil leak
The smell of burning oil when the engine is warm
Remanufactured Cylinder Head

A remanufactured cylinder head is a cylinder head that has been rebuilt with new parts. New valves, valve seats, seals, keepers, rockers, and bolts are typically installed. The cylinder heads are pressure tested to ensure they aren’t leaking and are crack-free. They are resurfaced, reassembled, and sometimes even repainted.
