Loss of power, warning lights, abnormal noise, overheating, or rough running are signs the engine is no longer operating within designed limits. Factory-level diagnostics before any mechanical intervention.
BOOK ENGINE REPAIRLive data logging from all engine sensors — MAF, MAP, O2, cam and crank position — identifies the exact fault before parts are replaced.
Timing belt or chain, tensioners and guides inspected and replaced at manufacturer intervals. Prevents catastrophic engine failure.
Cylinder head work, valve seat reconditioning, piston and bearing replacement carried out in-house with precision measuring equipment.
