Engine strip-down and clean
The engine is disassembled and washed to remove carbon. A clean surface reveals every fault and lets the new gaskets seat correctly.
New piston rings
We replace every piston ring with new. This is the single most important step for stopping oil consumption.
Complete timing chain kit
New chain, tensioners and guides. Ends the cold-start rattle and prevents a catastrophic engine failure.
Connecting rod bearings
We renew the rod bearings to secure the bottom end — avoiding far more expensive follow-up problems.
Valve stem seals
We replace all valve stem seals to stop oil seeping into the combustion chamber through the head.
Full gasket set
New cylinder head gasket, rocker cover gasket, oil pan gasket and all the other seals that the rebuild needs.
New head bolts
Torque-to-yield bolts are always replaced on reassembly — no shortcuts on durability.
Fresh fluids
New engine oil, oil filter and coolant — the engine gets a clean start.
Why repair beats swap
Repair or swap — why repair wins
A used replacement engine is often a gamble. We offer a transparent alternative.
Fix it once.
Fresh wear parts, documented work, warranty-backed.
You know what you're getting
When we rebuild your engine, every wear part (chain, rings, seals) is new. In a used replacement engine you don't know what's hiding inside.
Oil consumption solved
A used 'replacement engine' very likely has the same model-specific fault as the one it's replacing. A rebuild removes the issue for good.
Clear warranty
We warrant our labour and the installed parts. A used engine typically carries only a few weeks' warranty — if any.
Symptoms
When it's time for an engine rebuild
These are the symptoms that tell you the engine is asking for help.
High oil consumption
You're topping up oil every 1,000–3,000 km. A clear sign of worn piston rings or valve stem seals.
Blue smoke
The car puffs blue smoke on start-up or under acceleration. Oil is entering the combustion chamber.
Timing chain rattle
The engine rattles or clatters for a few seconds on cold start. The chain has stretched — a catastrophic-failure risk.
Power loss or rough running
The engine runs unevenly, compression has dropped, or the car hesitates under acceleration.

FAQ
Engine repair — frequently asked questions
What are the most common symptoms of engine trouble?
Watch for these: a Check Engine light, rough running or vibration, loss of power, unusual noises (knock, rattle), exhaust smoke or rapidly disappearing fluids. If even one symptom is persistent, book a diagnostic appointment.
Is it worth rebuilding the engine, or should I swap it?
It depends on the scope of damage. Often a rebuild (piston rings or a head overhaul) is cheaper and safer than buying a used engine. We always write a cost estimate for both options so you can decide with full information.
What does engine repair cost?
The base package starts at €1,999. Small gasket jobs run in the hundreds; larger rebuilds (rings, bearings) start from €2,500. You always get a written cost estimate after diagnostics, before work begins.
