Lot 9181: 1985 Rolls-Royce Silver Spirit

Based on my research and the specific vehicle details, here are the most common problems with the 1985 Rolls-Royce Silver Spirit:

1. Hydraulic Brake System Issues (Most Critical)

• Brake accumulator sphere failure - This is the #1 issue. The nitrogen-filled spheres degrade over time, causing brake warning lights and potential brake failure
• Expensive to replace (around $500-800 per sphere, and there are multiple spheres)
• Symptoms: brake pedal becomes hard, warning lights come on after braking

2. Electrical System Problems

• Power seat failures (as seen in this vehicle - passenger seat not working)
• Lighting issues (as seen - left high beam and side light not working)
• High-beam switch failure (as seen in this car)
• Dashboard electrical gremlins are common

3. Suspension Issues

• Play in suspension joints (as noted in this vehicle)
• Rear wheel bearing play (also noted)
• The complex hydraulic suspension system can develop leaks

4. Engine Oil Leaks

• Multiple oil leak points are common:
  • Steering box leaks (as seen in this vehicle)
  • Gearbox oil cooler leaks (also seen)
  • Valve cover gaskets
  • Oil pan gaskets

5. Age-Related Issues

• Dried out tires requiring replacement (as seen)
• Superficial corrosion on underside
• Interior wear on carpets and upholstery

6. Maintenance-Intensive Systems

• The 6.75L V8 engine requires regular maintenance
• Automatic transmission needs periodic service
• Air conditioning systems are problematic
• Cold start issues in cooler weather

What makes the 1985 model challenging:

• Parts are expensive and sometimes hard to find
• Requires specialist knowledge for repairs
• Many systems are unique to Rolls-Royce and not shared with other brands
• Labor costs are high due to complexity

The good news is that most of these issues are well-documented, and there are specialists who know these cars well. The hydraulic brake system should be your biggest concern - make sure it’s properly inspected before purchase.
