Engine Overhaul

priced after inspection

An engine overhaul is a complete teardown of the engine, inspection of every component, replacement of worn parts, and reassembly to the manufacturer's factory tolerances. We carry out cylinder block boring, piston and ring replacement, crankshaft grinding, and bearing shell replacement. But an overhaul isn't always the right call — sometimes it's cheaper to replace the engine with a contract unit, and we give you an honest assessment after the inspection before recommending the best option.

When to get in touch

If you notice any of these, it’s better not to wait:

  • The engine has lost a significant amount of power
  • Oil consumption has increased sharply
  • There's knocking from the pistons or crankshaft
  • Diagnostics showed low compression in multiple cylinders
  • There's scoring or wear on the cylinder walls
  • Metal shavings or a metallic sheen have been found in the oil
  • The engine has overheated and there's a suspicion of block or head damage
  • A local repair was done before but the problem has returned
  • The engine's mileage has significantly exceeded the manufacturer's stated service life

What an engine overhaul involves

An overhaul isn't about replacing a few worn parts — it's a complete restoration of the engine to a condition as close to factory-new as possible. Unlike a local repair, which fixes a specific fault, an overhaul covers the entire engine and requires a full teardown of the assembly.

An overhaul is used in cases where wear has affected several key engine components at once and a targeted repair no longer provides a lasting result.


Inspection — the first and decisive step

Before any work begins, we carry out a thorough inspection of every removed component to determine its actual condition and suitability for continued use. This inspection includes:

  • Measuring the cylinder block's geometry
  • Checking the crankshaft's condition
  • Examining the pistons, rings and connecting rods
  • Checking the cylinder head
  • Assessing the condition of the bearing shells

This inspection is what determines the real scope of work and the final repair cost, which is why we don't quote a final price until it's complete.


What the overhaul includes

Once the inspection is done and the scope of work is agreed, we carry out:

  • A complete teardown of the engine
  • Boring the cylinder block to the repair size
  • Replacing the pistons and piston rings
  • Grinding the crankshaft
  • Replacing the crankshaft and connecting rod bearing shells
  • Replacing gaskets, seals and other sealing components
  • Reassembling the engine to the manufacturer's factory tolerances and torque specs

Every step is carried out using measuring equipment, so all clearances and tolerances match the manufacturer's technical requirements.


Overhaul or contract engine

An overhaul isn't always the optimal solution. In some cases, especially with serious damage to the cylinder block or head, replacing the engine with a contract unit is cheaper and more reliable than a full rebuild.

After the inspection, we give you an honest picture of the engine's actual condition and present both options, explaining the pros and cons of each, so you can make an informed decision based on your budget and future plans for the vehicle.


Why an overhaul requires experience and precision

An overhaul is one of the most complex jobs in an auto shop. A mistake at any stage, from boring the block to final assembly, can cause the engine to fail again in a short time. We use measuring tools to control tolerances at every step and assemble the engine strictly to the manufacturer's technical requirements.

Frequently asked questions

An exact price can only be given after the inspection, since it depends on the actual condition of the parts and the scope of work required.

The inspection is a thorough check of every engine component after teardown, which determines which parts need replacing and which can be reused.

No. In some cases, especially with serious damage, replacing the engine with a contract unit is cheaper and more reliable. We honestly assess both options after the inspection.

The timeframe depends on the scope of work and ranges from several days to several weeks.

An overhaul includes cylinder block boring, piston and ring replacement, crankshaft grinding, bearing shell replacement, and replacement of gaskets and seals.

Signs that an overhaul is needed can include low compression in multiple cylinders, significant power loss, knocking from the pistons or crankshaft, and increased oil consumption.
