Frequently asked questions

What is the valve stem seal and what does it do?
The valve stem seal fits over the valve guide at the top of each valve stem in the cylinder head. It meters the oil lubricating the stem-to-guide interface and stops excess oil being drawn into the intake port or combustion chamber. It's used on Jaguar 3.0L supercharged V6 and 5.0L V8 petrol (AJ133) engines.
How many valve stem seals are needed for a full job?
Valve stem seals are sold individually and are typically replaced as a complete set, one per valve, so a full engine set covers every intake and exhaust valve. Most workshops renew all of them together while the cylinder head is off rather than replacing single seals.
What are the signs a valve stem seal needs replacing?
Worn valve stem seals typically harden and shrink with age and heat, letting oil seep past into the combustion chamber. Common signs are blue smoke on startup or after overrun and rising oil consumption on these Jaguar petrol engines. Left unreplaced, oil fouling can affect spark plugs and catalytic converters.
Which engines and Jaguar models does this seal fit?
This valve stem seal fits the Jaguar 3.0L supercharged V6 and 5.0L V8 petrol engines, both naturally aspirated and supercharged (AJ133). Applications include XK (X150), F-TYPE (X152), XF (X250/X260), XJ (X351), XE (X760) and E-PACE (X761). Confirm your engine before ordering.
