Valve Stem Seal for 2018-2019 Sea-Doo RXT STD 230 1503 - Replaces 420630200

Valve Stem Seal for 2018-2019 Sea-Doo RXT STD 230 1503, a direct replacement for OEM part number 420630200.

Valve stem seals fit over the top of the valve guides and control how much oil runs down the valve stem into the combustion chamber. Hardened or worn seals let oil past, leading to smoke, oil consumption and carbon build-up on valves and plugs.

When You Need It

• Blue smoke on start-up or deceleration
• Rising oil consumption
• Oil-fouled spark plugs or heavy carbon on the valves
• Any time the valves are removed

Fitting Tips

• Always fit new stem seals when the valves have been removed
• Use a seal installer to avoid damaging the seal lip
