MG MGF problems (1995–2002)

The only engine of the MG MGF that we have documented, the Rover K-Series, has high or critical severity faults in the versions it is fitted to. Our verdict for the versions it is fitted to: «With caution».[1][2][3][4]

Outside the engine: The sources we consulted barely document faults in the MG F outside the engine: Parkers mentions uneven build quality in the early cars, and that the TF replaced the Hydragas suspension with steel springs.[5][6]

MG MGF rating: acceptable reliability

Calculated using only 3 documented faults and their sources: the most serious and frequent faults weigh more. Provisional: we have found few sources for the rest of the car (suspension, brakes, electronics…). Its faults appear on the page, but they do not count towards the score or the rankings until the analysis is complete. How it is calculated

Documented engine

The first label is the most serious fault affecting that engine in this car; the second, our verdict for the versions it is fitted to. Each engine's risk index is calculated only from the faults that affect this car (how we calculate it). We only show engines we have documented with sources: if yours does not appear, we have not analysed it yet. View all engines

Verdict for the versions it uses

  • 1.6 16V 109-116 hp (16K4F, 1995-2005)1995–2005 · 109–116 hp · 16K4F

    With caution

    This is one of the versions where technical sources place the change to "damp" liners, with less coolant between cylinders; Diariomotor recommends checking whether the gasket is already the reinforced one.[1][2]

  • 1.8 16V 117-136 hp (18K4F, 1995-2005)1995–2005 · 117–136 hp · 18K4F

    With caution

    This is the version most cited in head gasket failures; it is worth buying if it already has the multi-layer (MLS) gasket with the liners measured, and Diariomotor considers its absence a good argument for negotiating the price.[1][2][3]

  • 1.8 VVC 145-160 hp (18K4K, 1995-2005)1995–2005 · 145–160 hp · 18K4K

    With caution

    It shares the 1.8's head gasket problem (suppliers sell specific multi-layer kits for the VVC); we have not found faults specific to the VVC mechanism in open sources.[3][4]

Faults that affect the MGF

  1. High severityFrequency: CommonCylinder head and blockHead gasket failureThe K-Series' big problem is the head gasket, which can fail even below 100,000 km because of a mix of gasket design, cooling and overheating. The usual repair uses the multi-layer steel (MLS) gasket that was developed for the Freelander.
  2. High severityFrequency: OccasionalCylinder head and blockSunken cylinder liners and warped head after overheatingAfter overheating, the K-Series liners can end up below the surface of the block and the aluminium head can be marked or warped; then no gasket seals properly and the liner height has to be measured and restored.
  3. Medium severityFrequency: OccasionalCoolingCoolant leaks: expansion tank cap, rear block rail and hosesThe K-Series circuit holds about 5.5 litres, so a slow leak empties the expansion tank and causes localised overheating. The points cited are the tank cap, the metal rail at the rear of the block (corrosion), the hoses and the coolant passages of the inlet manifold gasket.

Frequently asked questions

Is the MG MGF reliable?

The only engine of the MG MGF that we have documented, the Rover K-Series, has high or critical severity faults in the versions it is fitted to. Our verdict for the versions it is fitted to: «With caution». The sources we consulted barely document faults in the MG F outside the engine: Parkers mentions uneven build quality in the early cars, and that the TF replaced the Hydragas suspension with steel springs.

What problems does the MG MGF have apart from the engine?

The sources we consulted barely document faults in the MG F outside the engine: Parkers mentions uneven build quality in the early cars, and that the TF replaced the Hydragas suspension with steel springs. The most important documented faults are: uneven build quality in early cars (electrical system, low severity).[5][6]

What faults does the MG MGF have?

The most important by severity and frequency, on the engines we have documented, are: head gasket failure (Rover K-Series, high severity), sunken cylinder liners and warped head after overheating (Rover K-Series, high severity) and coolant leaks: expansion tank cap, rear block rail and hoses (Rover K-Series, medium severity).
