Different Types of Leakage Composite head gaskets are subjected
to a comprehensive testing
sequence. Hereby, approval for
installation is only given to topquality
and absolutely perfect
head gaskets. Nonetheless, leaks
can still occur during practical
operation, but only in exceptional
cases is this due to a faulty head
gasket. There are numerous
possible causes for damage to
composite cylinder-head gaskets.
Gas, Oil, and Coolant Leaks In professional terminology, leaks
between cylinder head, head
gasket, and engine block all fall
under the general term «leakage».
Hereby, a distinction is made
between gas, oil, and coolant
leakage, also known as «media
leakage».
In total, seven different types of media
leakage can occur with composite
head gaskets:
- Gas leakage between combustion
chambers
- Gas leakage from combustion
chamber to coolant circuit
- Gas leakage to the environment
- Oil leakage to the coolant
circuit
- Oil leakage to the environment
- Water leakage to the lubricant
circuit
- Water leakage to the environment

TIP
Leakage describes a permeable
point in a sealing system, through
which gases or liquids can escape
or enter. Leakage can cause the
entire sealing system to fail. |
