Product Name: LR166809 PCV Valve Service Kit / Crankcase Ventilation Repair Kit
Overview
The LR166809 is a PCV (Positive Crankcase Ventilation) valve service kit designed for Land Rover and Range Rover vehicles equipped with the 3.0L AJ20P6 petrol inline-6 engine.
This repair kit is a lower-level repair solution developed by Land Rover to address a common failure point: the rupture of the PCV diaphragm inside the camshaft cover. Instead of replacing the entire expensive camshaft cover assembly, this kit provides the necessary components to restore the PCV system to full functionality at a fraction of the cost.
The PCV system manages crankcase emissions by routing blow-by gases back into the engine for combustion. A failed PCV diaphragm can cause a range of drivability issues.
