Mercedes Sprinter T1N Valve Stem Seal Kit – Elring OEM | OM612 & OM647 2.7L | #6120500058 (2001–2006)

DESCRIPTION:

Worn valve stem seals are one of the most tell-tale engine issues on a high-mileage T1N Sprinter — and the symptoms are hard to miss. Blue smoke on cold startup that clears as the engine warms up, increased oil consumption with no visible external leaks, and carbon-fouled injector tips are all classic signs the seals have hardened and are no longer controlling oil flow past the valve guides. This Elring OEM valve stem seal kit for the OM612 and OM647 5-cylinder diesel restores proper oil control at every valve — a must-replace during any head removal or valvetrain service.

What This Kit Does

The valve stem seals sit at the top of each valve guide and meter the small amount of oil needed to lubricate the valve stems without allowing excess oil to enter the combustion chamber. The OM612 and OM647 use four valves per cylinder — 20 valves total — with both intake and exhaust seals required. When the seal material hardens or cracks from age and heat exposure, oil seeps past the guides into the combustion chamber, burning off as blue smoke and leaving carbon deposits that degrade combustion efficiency over time.

Common Symptoms of Worn Valve Stem Seals

• Blue or grey smoke from the exhaust on cold startup that clears at operating temperature
• Increased oil consumption with no visible external leaks
• Carbon buildup on injector tips or valves discovered during service
• Occasional blue puff of smoke during deceleration or after idling

When to Replace

Replace any time the cylinder head is removed for any reason — head gasket replacement, injector service, or valvetrain work. Always replace the full set simultaneously — partial replacement with a mixed set of old and new seals leads to inconsistent oil control across the cylinders.
