Is it worth repairing the engine or better to change cars?
It depends on three numbers: repair cost, the repaired car’s value and the condition of the rest of the vehicle. With the diagnosis done, we put all three on the table and the decision usually makes itself.
Signs an engine needs attention: growing oil consumption, blue smoke under acceleration, bubbling in the expansion tank or mayonnaise under the filler cap. None improves on its own. The honest approach — and what we do — is to measure before sentencing: a compression and leak-down test tells you in one morning whether you face a head gasket or general wear. Many "dead engines" that arrive at the garage are fixed without a rebuild; and when not, the failure usually traces back to postponed maintenance — so the best engine repair is still an oil change on time.
Frequently asked questions
How do I know if it is the head gasket?
Coolant loss with no visible leak, bubbling in the tank, emulsion in the oil or repeated overheating. Confirmed with a combustion gas test and a pressure test of the circuit.
How long does an engine repair take?
From several days for a cylinder head to weeks for a rebuild with machining. With the diagnosis we give you a concrete timeline.
Is a repaired engine as good as new?
A properly done rebuild to factory tolerances restores original compression and consumption, and comes with a written warranty.
My car is losing power — is it the engine?
Not always: turbo, intake, injection or a blocked exhaust give the same symptoms. That is why diagnosis always comes before the quote.
