All Known Issues

Aluminium Engine Cylinder Head Gasket Failure

ModerateEngine

Reliant's bespoke 748cc and 848cc all-aluminium overhead valve engines feature wet cylinder liners and an alloy cylinder head. If owners neglect the corrosion-inhibiting coolant mixture or let the radiator silt up, electrolytic corrosion attacks the head face and water jackets. This leads to cylinder head warpage and blown head gaskets, allowing combustion gases into the cooling jacket and coolant into the sump oil.

Est. Repair Cost: £250–£650
Warning Signs:

Milky emulsified oil residue beneath the oil filler cap and on the dipstick, White exhaust steam persisting even after the engine reaches running temperature, Bubbling and excessive pressure buildup inside the radiator header tank, Engine temperature gauge climbing quickly into the hot zone in urban traffic

What to Inspect:
  • Check under the oil cap and on the dipstick for signs of water-oil emulsion.
  • Inspect the coolant level and look for oily film or combustion bubbling.
  • Verify the service history confirms regular two-year antifreeze changes with proper corrosion inhibitors.

Single Front Wheel Kingpin and Headstock Bush Wear

ModerateSteering

The single front wheel configuration places all lateral steering forces and front braking loads through a single front suspension arm, kingpin, and steering headstock. The brass bushes and kingpins require periodic grease gun servicing every 1,000 to 3,000 miles. Neglected lubrication causes rapid ovality wear, inducing severe front-end steering shudder, vague directional stability, and uneven tyre wear.

Est. Repair Cost: £180–£420
Warning Signs:

Excessive play or vagueness around the straight-ahead steering position, Violent front wheel wobble or shimmy over tarmac ripples and cats eyes, Heavy clunking sensation over speed cushions and rough road surfaces, Uneven scalloped wear pattern developing across the front tyre tread

What to Inspect:
  • Jack up the front wheel and rock it vertically and horizontally to detect play in the kingpin and bearings.
  • Check the front suspension grease nipples for evidence of fresh lithium grease rather than dried dirt.
  • Test-drive on uneven roads to check for steering wheel vibration or darting.

SU Carburettor Throttle Spindle Wear and Fuel Hesitation

MinorFuel System

The SU HS2 carburettor fitted to 848cc engines develops air leaks past the brass throttle spindle bushes over time. This unmetered air leans out the fuel-air mixture, resulting in hesitation under acceleration, erratic hot idle, and difficult cold starting. Owners often over-enrich the mixture or leave the manual choke partially out to compensate, which fouls spark plugs and washes cylinder bores.

Est. Repair Cost: £90–£280
Warning Signs:

Lumpy or hunting idle speed that changes when pressing the throttle pedal slightly, Stumbling and flat spots when accelerating away from road junctions, Sooty fouled spark plugs from driving with the manual choke engaged, Noticeable fuel vapour smell around the carburettor body and engine bay

What to Inspect:
  • Gently wiggle the carburettor throttle spindle by hand to detect lateral play in the carb body.
  • Spray carb cleaner lightly near the throttle shaft while idling to listen for engine speed changes.
  • Verify the choke cable operates smoothly and retracts completely at the carburettor linkage.

Buying Tips for 1995 Reliant Robin

  • Inspect the steel chassis box sections and outriggers beneath the fibreglass floor; pre-1989 Mk1 models rot extensively near suspension pick-up points and rear spring hangers.
  • Check the single front wheel kingpin and steering arm for play by rocking the raised wheel vertically and horizontally, and verify grease nipples have received regular maintenance.
  • Inspect the engine oil and coolant for milky emulsification or exhaust steam, indicating an alloy cylinder head gasket failure or head face pitting.
  • Confirm whether the manual choke cable and SU carburettor operate smoothly, checking for throttle spindle wear that causes hesitation and uneven idle.
