High oil consumption, loss of compression, unusual engine noise or existing engine damage do not automatically mean that your MINI needs a different engine. We inspect the existing engine and rebuild it in our own workshop when a professional repair is technically and economically viable.

Engine and transmission overhauls are among the core specialisms of Miniparts24. We work on combustion-engine MINI models from the R50 generation onwards. The appropriate repair method depends on the engine variant, the type of damage, the condition of the components and the availability of the required parts.

When an engine overhaul may be worthwhile

  • High oil consumption or blue exhaust smoke: Wear affecting piston rings, cylinders, valve stem seals or other components can cause the engine to consume an unusual amount of oil.
  • Loss of compression and rough running: Starting problems, misfires, loss of power or significantly different compression readings can indicate internal damage.
  • Knocking or grinding engine noises: Unusual mechanical noises may be caused by damage to bearings, the crank assembly, pistons or the cylinder head.
  • Oil and coolant are mixing: Deposits in the coolant, oil in the cooling system or coolant loss can indicate damage to the cylinder head, head gasket or engine block.
  • Consequences of overheating or timing-chain failure: If the engine has overheated or the timing chain has jumped or broken, the actual internal damage must be assessed.

These symptoms are not enough for a reliable remote diagnosis. Measurements and a technical inspection are required to determine whether the engine can be rebuilt, a partial repair is sufficient or a replacement engine would be the more economical option.

Your MINI is no longer drivable? Describe its condition in the appointment request. Collection can be arranged in advance through our European pick-up and delivery service.

Rebuild, repair or replace the engine?

An engine overhaul does not mean that every component is automatically replaced. The engine is dismantled, cleaned and measured, then rebuilt according to the actual findings. Serviceable components are retained; worn or damaged parts are reconditioned or replaced.

If the existing engine block, cylinder head or crank assembly can no longer be reconditioned economically, we compare the available repair options. Depending on the damage, a suitable replacement engine may be the better solution. We do not make this decision from a fault code alone, but after a technical inspection and with your approval.

Typical scope of an engine overhaul

The exact scope depends on the engine and the type of damage. A complete overhaul typically includes the following inspections and work:

  • Removal, dismantling and thorough cleaning of the engine, cylinder head and the components required for the overhaul
  • Measurement and assessment of the engine block, cylinders, pistons, connecting rods, crankshaft and cylinder head
  • Honing, grinding, polishing or resurfacing components that can be reconditioned, where technically necessary according to the findings
  • Pressure and leak testing of the cylinder head where required by the engine variant and the damage
  • Replacement of the bearings, gaskets, piston rings, bolts and other wear parts required for the agreed repair
  • Replacement of the appropriate timing-chain kit and inspection of the oil and water pumps; any necessary replacement depends on the engine variant and findings
  • Professional reassembly, filling with the required fluids and adjustment or calibration of relevant components
  • Final checks for leaks and correct operation, fault-memory inspection and a road test where the condition of the vehicle permits

Not automatically included in the base price

  • Major components that cannot be reconditioned, such as the engine block, cylinder head, crankshaft, pistons or connecting rods
  • Ancillary components and assemblies such as the turbocharger, injection system, high-pressure fuel pump, alternator or air-conditioning compressor
  • Work on the clutch, transmission, cooling system or other vehicle components outside the agreed engine-overhaul scope
  • Pick-up and delivery service, workshop replacement vehicle and other optional services

Clear agreement after inspection: If dismantling reveals additional wear, we explain the cause, sensible repair options and the expected additional cost. Work outside the approved scope is only carried out after you have agreed to it.

Cost and turnaround time

The cost of an engine overhaul depends greatly on the engine, the damage and which components can be reused. The starting price applies to an engine that can be reconditioned within the intended base scope. A reliable calculation is often only possible after diagnosis and dismantling.

including VAT for the intended base scope

Deposit

25 %

for larger orders

Deposit, transport and warranty: A 25 % deposit is required for orders with an expected value above 1.500 € and for special orders. Collection and return transport are not included in the price and are calculated separately. Used and reconditioned parts fitted as part of the repair are covered by a 12-month warranty period. The terms agreed in the order apply; further information is available under Warranty and wear and tear.

The turnaround time also depends on the type of damage, the machining required and parts availability. After dismantling and inspection, we can assess the remaining work and provide a more realistic timeframe. If unexpected additional work is required, we agree the next steps with you.

How the engine overhaul works

  1. Send your request: Provide the full 17-character vehicle identification number, registration number, known faults and the most accurate description possible of the symptoms. You can upload photos, diagnostic reports and videos directly.
  2. Vehicle intake and diagnosis: We check the information, arrange delivery of the vehicle and initially assess the engine while it is still installed, where possible.
  3. Dismantling and inspection: The engine is removed, dismantled, cleaned and measured. Only then does the full extent of the damage become clear.
  4. Approve the repair scope: We explain the findings, the recommended repair method and possible additional costs. We then agree the final scope of work with you.
  5. Overhaul and final inspection: Once approved, we rebuild the engine, reinstall it and carry out the agreed functional and leak tests.

Frequently asked questions about engine overhauls

How can I tell whether my MINI needs an engine overhaul?

Possible signs include high oil consumption, blue exhaust smoke, loss of compression, loud mechanical noises, coolant in the oil or existing engine damage. These symptoms can have different causes. Only a technical inspection can determine whether an overhaul is necessary and possible.

Will my existing engine be rebuilt or will a replacement engine be fitted?

We first determine whether your existing engine can be professionally reconditioned. If major components cannot be repaired economically, we discuss whether a suitable replacement engine would be the better technical and economic solution.

How much does a MINI engine overhaul cost?

An engine overhaul starts from 3.999 € including VAT. The final price depends on the engine variant, the type of damage, the components that can be reconditioned and any additional parts required. We agree additional work with you before carrying it out.

How long does an engine overhaul take?

A reliable fixed timeframe cannot be given before dismantling. The extent of the damage, required machining and parts availability determine the turnaround time. After inspection, we can assess the remaining process and provide a more realistic timeframe.

Can a non-running MINI be collected?

Yes. Collection can be arranged in advance through our pick-up and delivery service. The cost depends on the distance and transport required and is calculated separately.
