⚙️ Key Features

• 9 grams
• Supersedes 3853132, catalogued earlier as a valve stem seal
• 57 listed applications
• Engine group
• Quantity varies by assembly, most commonly 8

🔌 Function

Controls the oil passing along the valve stem into the guide, letting enough through to lubricate it while keeping the rest out of the combustion chamber.

⚠️ Common Signs of Failure

• Puff of blue smoke on start-up or after a period at idle
• Oil consumption rising with no external leak
• Oily deposits on the valve stems and heads found on strip-down
• Seals found hardened, cracked or split when the springs come off
• Smoke on the overrun coming down from cruising revs

🛠️ Service Notes

• Renew all the seals on a head at once rather than singly - they age together
• Valve stem seal 3855049 is a separate 23 gram part in the same round, so check which one the head actually takes
• Check the valve guides for wear before fitting new seals, as worn guides will smoke again regardless
