HEAVY MECHANICAL ENGINE REPAIR &
OVERHAUL EXPERTISE
Precision timing belt & chain replacements, cylinder head resurfacing, blown head gasket repairs, and complete engine rebuilds at 265 Centennial Pkwy N Unit 3, Hamilton.
When an engine suffers from low compression, severe overheating, broken timing components, or internal bearing failure, you need certified mechanics with heavy mechanical precision tooling rather than simple part-swappers.
At Centennial Tire & Auto Service in Hamilton, our licensed engine rebuilders specialize in complete cylinder head overhauls, MLS head gasket replacement, valve guide repairs, timing chain guide rebuilds, and complete crate engine swaps with total factory precision.
Interference engine timing belt replacements, hydraulic tensioners, and variable valve timing (VVT) phasers.
Multi-layer steel (MLS) head gasket replacements, deck resurfacing, valve grinding, and crack pressure testing.
Rod bearing inspections, crankshaft polishing, high-pressure oil pump replacement, and oil gallery cleanouts.
Internal water pumps, thermostat housings, radiator core flushes, and thermal relief bypass valve repairs.
💨 Thick White Sweet-Smelling Smoke
Blown head gasket leaking pressurized coolant directly into the combustion chamber.
🔨 Deep Metallic Engine Knock
Spun rod bearing or wrist pin play indicating severe oil starvation; shutdown engine immediately.
🥛 Milky "Milkshake" Oil on Dipstick
Engine oil and coolant mixing inside crankcase due to failed oil cooler or cracked head.
🌡️ Rapid Engine Overheating
Failed water pump impeller or blocked coolant passages causing localized thermal warpage.
Cylinder bore scope camera inspection and digital compression leakage audit.
Component micrometer measurement, head skimming, and ultrasonic cleaning.
Reassembly to factory angle specs, timing sync, oil pressure priming, and road test.
Timing belts are rubber and require mandatory replacement every 100,000 to 160,000 km to prevent catastrophic valve piston contact. Timing chains are metal and lubricated by engine oil; they are replaced when low oil maintenance causes chain stretch or guide wear.
If caught early without cylinder head warping or bottom-end bearing damage, a head gasket replacement with machine resurfacing is far more cost-effective. We perform full leak-down testing first to recommend the most economical option.
