BGA’S ENGINE VENTILATION RANGE. UK Market Leaders.
Rocker Cover function on an engine:
The rocker cover, or valve cover, shields valve train components, preventing oil leaks and ensuring lubrication, thus enhancing engine longevity and efficiency.
Inlet Manifold function on an engine:
An inlet manifold distributes air or air-fuel mixture to engine cylinders, optimizing combustion and performance. Both parts play crucial roles in maintaining the engine's operational integrity and efficiency.
All quality testing for Engine Ventilation parts are carried out in BGA’s Headquarters in Wiltshire, United Kingdom. Quality Certificates

COMMON CAUSES OF OEM ROCKER C Rocker Cover failure can stem from various factors, including:
1 2 3 4
MATERIAL FATIGUE
Over time, heat fluctuations and warping can cause the rocker cover's material to weaken, leading to cracks or breaks that compromise its structural integrity.
POOR INSTALLTION
Incorrectly fitted rocker covers may not seal properly, leading to oil leaks and potential exposure of internal components to external contaminants.
GASKET FAILURE
The gasket between the rocker cover and the engine may deteriorate, resulting in oil leaks, reducing effective lubrication and exposing the engine to potential damage.
CORROSION
5 MANUFACTURE DEFECT
Constant exposure to heat, moisture, and chemicals can cause the metal components of the rocker cover to corrode, leading to failures in its protective role.
Imperfections during the manufacturing process, such as subpar materials or design flaws, can make the rocker cover more prone to premature failure and malfunctions.

WITH “SWIRL FLAPS”
UA
RANTEE
D
The function of the swirl flaps is to control the flow of fresh air into the combustion chamber efficiently at different engine loads and speeds. It does this by altering the path of which the air travels through the manifold and into the combustion chamber by opening and closing the flaps to direct the air through these different paths. The paths are of different length and cross-sectional area causing the air to speed up or slow down allowing the maximum efficiency/performance of the engine at higher or lower RPM.
Example of carbon deposit build up.
The bad bits:
Intake manifolds can become blocked with carbon deposits from the combustion process. These soot-like deposits can harden and restrict the flow of air into the engine causing lack of power, hesitation, poor fuel economy and eventually damage to the intake manifold flaps and even the motor or valve that controls them.
BGA Recommend
When replacing the manifold, we recommend that the motor or valve that controls the swirl flaps is checked prior to replacement of the manifold to ensure it has not been damaged due to the flap movement being hindered by the carbon deposits on and around the swirl flaps. It is also advised to check the throttle valve and inlet valves for further carbon deposits and clean where necessary.
