PTFE Split Seal - a split polytetrafluoroethylene sealing ring used in the variable cam timing (VCT) gear of the AJ-series V8 petrol engine.

The seal sits within the variable valve timing assembly, sealing the oil-fed phaser that advances and retards camshaft timing under engine control. Its split, open-ended form lets it be fitted over the shaft without full disassembly of the gear. Used on the 4.2L supercharged and 4.4L naturally aspirated AJ V8 petrol engines.

Frequently asked questions

What is the 1237728 PTFE split seal used for?
The 1237728 PTFE split seal seals the oil-fed variable cam timing (VCT) phaser in the AJ-series V8 petrol engine. The phaser advances and retards camshaft timing under engine control, and this seal keeps the pressurised oil feed contained. Its split shape lets it fit over the shaft without fully stripping the timing gear.
Which engines and models does this seal fit?
This seal fits the 4.4 V8 naturally aspirated and 4.2 V8 supercharged AJ petrol engines. That covers the Discovery 3 (2005-2009), Range Rover L322 (2002-2009) and Range Rover Sport L320 (2005-2009). Confirm your engine variant before ordering.
Can the split seal be reused once the timing gear is opened up?
No, this split PTFE seal should be replaced whenever the variable cam timing gear is disturbed. Refitting the original risks a poor seal on the phaser oil feed, which can upset cam timing. Fit a new one as standard during any VCT or timing cover job.
What happens when the VCT phaser seal fails?
A failed VCT seal typically causes a loss of oil pressure at the cam phaser, which can trigger variable valve timing fault codes and a rattle from the timing gear, usually worst on cold start. Rough running and reduced performance can follow on the AJ V8.
