Function:

In many modern four-stroke engines, the cylinder
head cover houses the upper actuation elements of
the engine control unit as well as the valves in the
crankcase ventilation with all its peripheral devices
It also prevents leakage of the lubricants in the
environment. Additionally, it protects the engine
from dirt or other foreign objects.

SYMPTOMS
• Seal is leaking: Vehicles leak oil
• Smell of oil when running
• Valves blocked: jerky engine running, in
extreme cases the engine light lights up
until engine damage occurs

REASONS FOR FAILURE
With advanced mileage the following
problems arise:
• Seals become leaky and have to be
replaced
• Integrated valves for the crankcase
ventilation clog up frequently
• Holders of the cylinder head covers
tear if improperly mounted and also
sometimes due to age

CONSEQUENTIAL DAMAGES
• Engine oil leaks out
• The engine does not run smoothly

WHAT ARE HALDEX CLUTCHES
AND WHAT ARE FILTERS FOR?

The all-wheel drive on some SUVs from Audi, Volkswagen,
Volvo, Opel, Land Rover, and Ford brands operates thanks
to the distribution of torque between the front and rear axles
through the Haldex, an intelligent coupling that manages the
connection between the two axles.
Haldex clutch filters are an important part of the transmission
mechanism. These filters are designed to protect the internal
components of the system, ensuring proper functionality and
increased longevity.
Automobile manufacturers recommend the periodic replacement
of filters every 70,000 km to ensure adequate
functionality of the all-wheel-drive system. Failure to replace
them can cause clogging, blocking the regular flow of oil, and
leading to severe damage to the system.
Replacing Haldex clutch filters during preventive maintenance
interventions can help reduce long-term repair costs.

Trasmission filters

Transmission Filters
Contaminants can enter your transmission fluid system in the manufacturing process. They can also enter the transmission through the vent, or through the dipstick and fill tube during fluid level checking/filling. Most of the time, however, contaminants are the result of normal wear. These contaminants consist of metal chips and flakes from gears and bushings and fine fibrous material from clutch facings.
AVS Autoparts transmission filters protect transmissions against contaminants in the transmission fluid system. Proper filtration helps improve transmission life by minimizing wear and preventing sticking and scoring of sensitive shift control valves. In the event of a part failure, the filter also guards against secondary damage to other parts and thus helps to minimize repair costs.
