Engine overhaul (popularly known as "engine reassembly") is the removal of the engine from the vehicle, disassembly, renewal of worn parts and reassembly at factory values. A properly diagnosed engine overhaul can be done at a budget well below the cost of purchasing the vehicle. to mint condition brings it closer.
What symptoms suggest revision?
- Fat burning: Blue smoke from exhaust, need to top up oil at short intervals
- Low compression: Cylinder pressure loss verified by measurement
- Power loss and irregular operation: Problems that persist even though the ignition and fuel system are intact
- Excessive engine noise: Bearing knocking, valve noise, chain/tensioner noises
- Damage after overheating: Cylinder head deformation, gasket leakage
Not all of these symptoms mean revision. Air leak, injector malfunction or sensor error can have similar results. Therefore, the decision to revise after measurement is given.
Revision process: step by step
- Diagnostics and measurement: Fault recording, compression test, leak test and endoscopic control if necessary.
- Dismantling: The engine is removed from the vehicle, peripheral units (turbo, manifold, plumbing) are separated.
- Disassembly and cleaning: Block, cover, crank, pistons are cleaned and measured.
- Machine operations (Cylinder head machining): The cylinder head surface, valve guide and bearings are machined as necessary.
- Part renewal: Ring, bearing, gasket set, valve, tensioner/chain system and other necessary parts are renewed. here original or original piece is preferred.
- Collection: Collection in accordance with factory torque values and tightening order; The cleanliness of the oil channels is checked.
- Operation and testing: First start, oil pressure check, idle and road test.
Overhaul or new engine?
| Status | Suggestion |
|---|---|
| Block and crank solid, wear limited | Revision (Cylinder head machining + parts renewal) |
| Crack in the block or severe damage to the crank | Original engine + processing of existing engine |
| The vehicle will be used for many years | Revision; Warranty coverage is clearer |
The decisive factor in both ways is the engine speed. why that it is damaged. If there is damage caused by overheating, lack of oil or incorrect fuel, simply replacing the engine will not prevent the same problem from recurring; The feeding system also needs to be checked.
How long does it take?
Duration; varies depending on the type of engine, parts supply and scope of machine operations. Therefore, time estimation can only be made after disassembly and measurement. clear can be given as . Instead of saying "this many days" at the beginning, the parts list and schedule are discussed together after the measurement.
Warranty
For engine work we provide a 5,000 km warranty; for labour and spare parts, in case of a manufacturing or workmanship defect, replacement applies. We state in writing upon delivery which work is covered and how.
If you are suspicious about your engine: what symptoms are there, how long it has been, what maintenance has been done - share these and we can make a preliminary evaluation over the phone.
Does your vehicle have such a symptom?
Explain the symptom over the phone; Let us provide preliminary information free of charge and make an appointment if necessary.
