what are the common problems with the 560SL?

Question

Accepted Answer

The Mercedes-Benz 560SL (R107 chassis) is generally a robust car, but like any classic, it has some known weak points you should keep an eye on:

**Engine & Drivetrain**
- **Timing Chain & Tensioners** – A critical maintenance item. Early models (1981-1984) had single-row chains that are prone to stretching; later cars got dual-row chains which are more durable but still need regular inspection.
- **Hydraulic Lifter Noise** – Ticking from the top of the engine often indicates worn hydraulic tappets/rocker arms. This is usually caused by infrequent oil changes or incorrect oil grade. Can cost $2,000-3,000 to fix.
- **Exhaust Manifold Gasket Leaks** – Common on V8 models; cracked manifolds around the EGR valve area are typical. A heat-affected ticking sound at startup that quiets as the motor warms up is the telltale sign.
- **Camshaft Wear** – Can occur if regular maintenance has been neglected. Listen for ticking that could indicate this.

**Rust (The Big One!)**
The R107 is notorious for rust. Key areas to inspect:
- Bulkhead/firewall (leads to damp footwells inside)
- Above the headlamps, hood, and trunk lid
- Rear wheel arches, door bottoms, sills
- Rear valances and bumper corners (they trap moisture)
- Floors and trunk/boot floor

**Cooling System**
- Radiator leaks/clogs – The radiators are vulnerable to stone damage and core blockage. These engines run hot, so cooling system maintenance is critical.
- Water pump failures
- Aging hoses and thermostat issues

**Electrical & Accessories**
- **Headlamps** – Dimmer over time due to tarnished reflectors or cracked lenses
- **Headlamp Washers** – Often corroded or inoperative
- **Cruise Control** – Control box failures are common
- **Fuel Pump & Relays** – Can fail with age
- **ABS Sensors** – Can cause warning lights, especially on the 300SL, but also affects 560SLs

**Suspension & Steering**
- **Vague Steering** – Worn steering box and steering damper
- **Suspension Rattles** – Worn anti-roll bar links, shock absorbers, bushings

**Body & Interior**
- **Soft Top/Hard Top Seals** – Worn seals cause wind noise and water leaks
- **Dash Pad Cracking** – Very common
- **Damp Boot/Trunk** – Spare wheel well collects water from poor seals or rear lamp leaks
- **Window & Mechanism Woes** – Cables and regulators can fail

**Fuel System**
- Rough running, flat spots, or misfiring often stem from injection system issues that need tuning or component replacement.

The good news? These are well-documented cars with excellent parts availability and strong specialist support. A well-maintained 560SL is a joy to own. Just be sure to buy on condition, not just low mileage, and get a thorough pre-purchase inspection from a Mercedes specialist.
