Frequently asked questions

What does the LR166809 PCV valve service kit do?
The LR166809 services the positive crankcase ventilation valve on the 3.0L AJ20P6 Ingenium petrol engine. The PCV valve meters blow-by gas out of the crankcase back into the intake, keeping crankcase pressure controlled as intake vacuum changes with load. Allmakes supplies this as an aftermarket kit.
Which engines and models does this PCV kit cover?
The 3.0L AJ20P6 petrol in High output form, fitted to the Discovery 5 from 2017, Defender L663 from 2020, Range Rover L405 2013 to 2022, Range Rover Sport L494 2014 to 2022, and Range Rover Velar from 2017. It's specific to that engine, not the diesel.
What are the symptoms of a failed PCV valve on an Ingenium petrol engine?
A perished PCV diaphragm typically shows as rising oil consumption, an unstable or hunting idle, and unmetered air entering the intake. Excess crankcase depression can also pull oil past seals. On the AJ20P6 these symptoms often get mistaken for a boost leak or a coil fault.
Where is the PCV valve located on the AJ20P6?
In the crankcase ventilation circuit between the cam cover and the intake tract on the 3.0L AJ20P6. Access typically means removing intake ducting and engine cover pieces to reach the valve assembly. It sits under emission control, crankcase, in the parts catalogue.
Should anything else be replaced at the same time?
Check the crankcase ventilation hoses and the cam cover while the PCV valve is off the 3.0L AJ20P6. Hardened or split hoses give the same idle and oil consumption symptoms as a failed valve, and a fresh valve on a leaking hose won't fix the fault.
