AKUSAN LCCM 01028 M Rocker Cover PCV Valve Membrane
Replacement crankcase ventilation diaphragm designed to repair the integrated PCV valve inside compatible Opel, Vauxhall and Chevrolet rocker covers.
The AKUSAN LCCM 01028 M membrane provides a cost-effective alternative to replacing the complete cylinder-head rocker cover when only the internal crankcase breather diaphragm has failed.

Condition: Aftermarket NEW
INTRODUCTION
The Positive Crankcase Ventilation valve regulates pressure and oil vapour flow inside the engine crankcase. On compatible engines, the PCV valve is integrated into the rocker cover and uses a flexible rubber diaphragm.
Continuous exposure to engine oil, vacuum and high temperatures can cause the original membrane to harden, split or tear. Replacing the damaged diaphragm can restore correct crankcase pressure regulation without purchasing a complete rocker cover assembly.
PROBLEM / SOLUTION
- Helps eliminate whistling or hissing noises from the rocker cover
- Helps restore stable engine idle
- Helps reduce excessive crankcase vacuum
- May reduce increased engine oil consumption caused by a torn diaphragm
- Helps prevent unmetered air entering the intake system
- May resolve lean-mixture faults associated with a defective PCV membrane
- Cost-effective alternative to replacing the complete rocker cover

FUNCTION
The membrane reacts to intake-manifold vacuum and regulates the flow of crankcase gases through the engine ventilation system.
A correctly functioning diaphragm maintains controlled crankcase pressure, limits excessive oil-vapour transfer and prevents unmetered air from entering the intake system.
IMPORTANT NOTICE
Please compare the original part number, membrane design and rocker-cover construction before ordering.
This item repairs only the integrated PCV membrane section. It will not repair a cracked or warped rocker cover, blocked breather passages or other mechanical faults within the crankcase ventilation system.
Compatibility cannot be confirmed using only the vehicle model or engine capacity.
If you are unsure, please send us your vehicle VIN, engine code or clear photographs of the original rocker-cover PCV section before purchase.
Carefully inspect and clean the PCV housing before installation. The sealing surfaces must be free from damage, dirt and hardened sealant.
Professional installation is recommended.
