Mercedes Sprinter T1N Hydraulic Valve Lifter – LUK | OM612 & OM647 2.7L | #6110500225

DESCRIPTION:

A worn or collapsed hydraulic valve lifter on the T1N Sprinter's 5-cylinder diesel is one of the most common causes of valve train ticking, rough idle, and loss of power on higher-mileage engines — and it's often misdiagnosed as a camshaft or oil pressure issue before the lifters themselves are inspected. This LUK hydraulic valve lifter restores correct valve actuation and eliminates the ticking at the source. Sold individually — 20 lifters required per engine.

What This Part Does

The hydraulic valve lifter (also called a cam follower or tappet) sits between the camshaft lobe and the valve stem, transferring camshaft rotation into precise valve opening and closing motion. The hydraulic design uses engine oil pressure to automatically maintain zero valve clearance — eliminating the need for periodic valve adjustment. When the lifter's internal check valve wears or the oil passages clog from sludge, it loses hydraulic pressure, collapses, and the affected valve no longer opens to full lift — causing ticking, rough running, and reduced cylinder efficiency.

Common Symptoms of a Failing Lifter

• Persistent valve train ticking or tapping, especially on cold start
• Ticking that may reduce at operating temperature but doesn't disappear
• Rough idle or slight misfire on one or more cylinders
• Reduced power on the affected cylinder

When to Replace

Replace when valve train ticking is confirmed to be coming from a collapsed or worn lifter, or during any major engine rebuild. Flush the engine oil system with fresh oil before installing new lifters to ensure clean oil reaches the hydraulic circuits immediately on startup. Always replace in matched sets by cylinder bank or as a full set — mixing old and new lifters on the same camshaft causes uneven wear.
