  2. Engine wear - resource L20 is ~200,000 km, but most specimens have long exceeded this limit. Typical faults:
    • 🔧 Oil fasting due to clogged channels.
    • 🔥 Overheating (weak radiator and thermostat).
    • 🛢️ Seal leakage (especially the rear crankshaft).
  • Electrics - old relay, wiring And generators often fail. Particularly problematic distributors And ignition coils.

    • Other typical faults:

    Knot Problem Solution
