1997 LAND ROVER DISCOVERY

Typical onset: 60,000-120,000 mi

Symptoms: Coolant consumption with no visible leaks, White smoke from exhaust on cold start, Overheating with no apparent cause, Milky oil or coolant in oil, Rough idle or misfires that progressively worsen

Fix: The Rover V8 from this era has thin-wall cylinder liners that crack or shift, allowing coolant into the cylinders. Only real fix is a complete engine rebuild with sleeved block or a replacement short block. 20-30 hours labor plus machine work. Many owners opt for used engines, which is gambling on the same problem.

Estimated cost: $4,000-7,500

Typical onset: 70,000-100,000 mi

Symptoms: Overheating under load, Coolant loss without external leaks, Bubbles in coolant reservoir when running, Exhaust gases in cooling system (combustion leak test positive), Loss of power and rough running

Fix: Often confused with liner issues but can occur independently. Requires both heads off, resurfacing, and new gaskets. Figure 12-16 hours labor. Problem is many shops do heads only to find the liners have also slipped—then you're into a full rebuild anyway.

Estimated cost: $2,500-4,000

Typical onset: 80,000-150,000 mi

Symptoms: Low oil pressure warning at idle when hot, Knocking or ticking from bottom end, Metal shavings in oil during changes, Sudden catastrophic engine failure, Oil light flickering during hard cornering

Fix: The oil pump wears and loses prime, starving the bottom end. Once bearings are damaged, you need crank out, machining, new bearings, often new pistons if debris circulated. Effectively an engine rebuild. 25-35 hours.

Estimated cost: $5,000-8,000

Typical onset: any mileage

Symptoms: ATF puddle under vehicle (pink/red fluid), Sudden loss of all transmission fluid, Transmission overheating or slipping, Cooler lines rusted through at chassis mount points

Fix: The steel cooler lines rust through where they contact the frame, especially in salt states. If you catch it early, just replace the lines (2-3 hours). If the trans runs dry, you're looking at a rebuild or replacement. Always inspect these during any service.

Estimated cost: $300-600 for lines only; $2,500-4,000 if trans damaged

Typical onset: 60,000-100,000 mi

Symptoms: Clunking on acceleration or deceleration, Vibration at highway speeds, Squeaking or grinding underneath when moving, Sudden loss of drive (if U-joint separates)

Fix: The two-piece driveshaft has three U-joints and a center support bearing that wear out. Most shops replace the whole shaft assembly rather than rebuild due to balancing issues. 2-4 hours labor. There was an NHTSA recall but many weren't fixed.

Estimated cost: $600-1,200

Symptoms: Water pooling in footwells after rain, Musty smell in cabin, Wet carpet under front seats, Headliner sagging or stained near sunroof, Electrical gremlins (windows, locks)

Fix: The sunroof drains clog with debris and overflow into the cabin. Drain tubes run down the A-pillars and exit behind front wheels. Clear them with compressed air or flexible wire. Preventive cleaning takes 30 minutes. If water has been sitting, you may need to pull carpet and dry everything to prevent mold and ECU damage.

Estimated cost: $0-50 DIY; $150-400 if shop dries interior

Typical onset: any mileage

Symptoms: ABS light, traction control light, and hill descent control light all on together, ABS and traction control non-functional, No braking issues but warning lights constant

Fix: Usually a failed wheel speed sensor or corroded shuttle valve switch in the ABS modulator. Diagnosis requires a scan tool that reads Land Rover ABS codes. Wheel sensors are cheap and easy (1 hour), shuttle valve switch is 2-3 hours and requires bleeding the system. Modulator replacement is rare but $1,500+ if needed.

Estimated cost: $150-400 for sensor/switch; $1,800-2,500 for modulator
