Vehicle compatibility depends on the engine version, valve stem diameter and cylinder head specification. Always confirm fitment before purchasing.
How Do Supertech Valve Stem Seals Work?
Valve stem seals regulate the amount of oil passing between the valve stem and valve guide.
Correct lubrication is essential for reducing valve train wear while preventing excessive oil from reaching the intake ports and combustion chambers.
Over time, valve stem seals can deteriorate due to heat, engine oil exposure and normal operating conditions.
Common Symptoms of Worn Valve Stem Seals
- Increased engine oil consumption
- Blue exhaust smoke during startup
- Excessive oil deposits around intake valves
- Oil-related combustion chamber deposits
- Poor valve stem oil control
Replacing worn valve stem seals with correctly sized Supertech components can help restore proper oil regulation.
Please note that blue smoke and oil consumption can also result from worn piston rings, damaged valve guides or other mechanical problems.

The Supertech 6mm intake valve stem seal set is a practical replacement component for a wide range of compatible engine-building projects.
Common applications include:
- Toyota Supra Mk4 engine restoration

For modified engines, always verify compatibility with aftermarket valves, guides, springs and other valve train components.
