description

The valve stem seal is the sealing part of valve train, installed on top of valve guide and fits tightly on valve stem. It controls oil supply for valve stem and stops oil leaking into cylinder. Aged rubber, worn lip and lost garter spring will cause blue smoke on cold start, excessive oil consumption and heavy carbon deposit. Severe carbon sticking shifts valve timing.

FAQ 

Q: Can I replace only leaking valve stem seals?
A: Not recommended. Remaining seals have aged rubber and may leak soon, full set replacement is preferred.

Q: Blue smoke only on cold start and disappears when warm, is it definitely valve seal fault?
A: Most likely caused by hardened seal lip, but piston ring and cylinder liner wear also need inspection.
