1. Exact inner diameter fits valve stem tightly, effectively blocks engine oil from entering combustion chamber and eliminates oil burning issue.
2. Premium fluororubber material withstands long-term high temperature inside cylinder head, resistant to aging, hardening and cracking.
3. Built-in stainless steel spring provides continuous uniform clamping force for stable long-term sealing performance.
4. Ideal replacement parts for cylinder head overhaul, valve maintenance and solving blue smoke exhaust as well as excessive oil consumption.

Valve stem oil seals are installed on intake and exhaust valve guides to control engine oil infiltration. After long service time, seals will lose elasticity and cause oil to burn inside cylinders, resulting in blue smoke during acceleration, frequent oil level drop and heavy carbon deposits on pistons.

This 12-piece set fully matches the 6-cylinder Toyota 1HZ diesel engine. Professional installation with dedicated valve spring compressor tool is required to avoid scratching valve stems and damaging seal lips.
