1994 TVR GRIFFITH

Typical onset: 50,000-80,000 mi

Symptoms: Temperature creeping past halfway mark in traffic, Steam from under clamshell hood, Coolant loss with no visible leaks, Cracked or warped cylinder heads after overheat event

Fix: Rover V8 runs marginal cooling from factory; TVR installation makes it worse with tight packaging. Requires radiator replacement (often upgrade to aluminum triple-core), new water pump, thermostat, hoses, and complete flush. If heads lifted from overheating, expect machine work and head gasket job adding 12-16 hours labor. Prevention is everything here.

Estimated cost: $1,800-4,500

Typical onset: 60,000-100,000 mi

Symptoms: Clunking on shifts or acceleration/deceleration, Vibration through chassis at highway speed, Visible movement of transmission tailshaft, Shifter slop or difficulty finding gears

Fix: TVR used tubular crossmember with rubber mounts that deteriorate; aggressive driving cracks the tubes themselves. Requires fabrication or sourcing TVR specialist parts from UK. Transmission must be supported and crossmember removed—tight workspace means 6-8 hours labor even for experienced tech. Many upgrade to polyurethane mounts simultaneously.

Estimated cost: $1,200-2,200

Symptoms: Intermittent gauge failures, No-start with good battery, Headlights dimming at idle, Mysterious electrical drains, Corroded fuse terminals causing random faults

Fix: Classic British Lucas components age poorly. Alternator rebuilds fail frequently (upgrade to higher-amp modern unit recommended). Main fusebox under dash corrodes—cleaning and dielectric grease is temporary; replacement is 4-5 hours due to hand-built wiring looms. Ground points behind body panels require disassembly to access and refurbish. Diagnostic time adds up fast with intermittent faults.

Estimated cost: $800-2,500

Typical onset: 40,000-70,000 mi or after sitting

Symptoms: Pulling to one side under braking, Handbrake ineffective or stuck on, Brake fluid weeping from caliper bodies, Excessive heat and brake fade, Uneven pad wear

Fix: AP Racing or Girling calipers used depending on year; seals deteriorate and pistons corrode if car sits or fluid not changed regularly. Rebuild kits available but often pistons need replacement. Front calipers 3-4 hours labor, rears 2-3 hours. If rotors grooved from seized caliper, add rotor replacement. Cars stored winters see this frequently.

Estimated cost: $1,200-2,000

Typical onset: 70,000-120,000 mi

Symptoms: Hard starting when warm, Hesitation or stumble under acceleration, Fuel smell in cabin or engine bay, Stalling after sitting, Check engine light with lean codes

Fix: Rubber fuel lines from early 90s deteriorate internally; particles clog filter and injectors. In-tank pump access requires body removal on some models or cutting access panel—specialist job. Filter changes every 15k miles prevent issues but often neglected. Full fuel system refresh including lines, filter, pump, and injector cleaning runs 8-10 hours labor due to chassis access challenges.

Estimated cost: $1,500-3,000

Symptoms: Surface rust on exposed chassis tubes, Perforation near suspension mounting points, Cracking paint on lower chassis, Structural flex or creaking over bumps, Failed MOT/inspection for frame integrity

Fix: Tubular steel chassis wasn't galvanized; UK cars see extensive corrosion, US cars less so but still vulnerable at jacking points and lower tubes. Repair requires media blasting, cutting out bad sections, welding in new tubing, and complete repaint. Fiberglass body comes off for proper access—specialist-only work, 40+ hours for comprehensive restoration. Prevention is POR-15 or similar applied to bare metal every few years.

Estimated cost: $5,000-12,000
