Engine Repair

Precision timing belt and chain replacements, cylinder head resurfacing, head gasket repairs, internal engine repairs, and complete engine rebuilds performed by experienced technicians at Centennial Tire & Auto Service in Hamilton.

Advanced Internal Engine Repairs & Rebuilding

When an engine experiences low compression, severe overheating, broken timing components, or internal bearing failure, proper diagnosis and precision mechanical work are essential.

At Centennial Tire & Auto Service, our licensed engine technicians specialize in cylinder head overhauls, MLS head gasket replacement, valve guide repairs, timing chain guide replacement, internal engine repairs, and complete engine replacements using quality components and factory-level procedures.

Core Engine Repair Disciplines

Premium oil and filtration designed for modern engines, demanding driving conditions, and maximum protection between services.

Timing Belt & Chain Systems

We perform precision timing belt and timing chain repairs, including interference-engine timing services, hydraulic tensioner replacement, and variable valve timing (VVT) phaser repairs.

Head Gasket & Cylinder Heads

Our cylinder head services include MLS head gasket replacement, deck resurfacing, valve grinding, and pressure testing to identify cracks and ensure proper sealing.

Oil Pump & Internal Bearings

We inspect and service critical internal components including rod bearings, crankshafts, oil pumps, and oil galleries to restore proper lubrication and engine reliability.

Cooling System & Water Pumps

We diagnose and repair internal water pumps, thermostat housings, coolant passages, radiator systems, and thermal relief components to prevent overheating and engine damage.

Symptoms of Critical Engine Failure

Thick White Sweet-Smelling Smoke : Persistent white smoke with a sweet smell can indicate coolant entering the combustion chamber due to a failed head gasket or damaged cylinder head.
Deep Metallic Engine Knock : A deep knocking sound may indicate severe internal bearing wear or oil starvation. Continued operation can result in major engine damage.
Milky Oil on Dipstick : Creamy or milky engine oil can indicate coolant contamination caused by a failed oil cooler, head gasket, or cracked engine component.
Rapid Engine Overheating : Rapid or repeated overheating may result from a failed water pump, restricted coolant passages, thermostat problems, or other cooling-system failures.

Our 3-Stage Engine Repair Process

Our engine repair process combines comprehensive diagnostics, precision machining, and factory-specification assembly to ensure every repair is completed with accuracy and reliability.

Pressure & Leak-Down Testing:
Digital compression testing, cylinder leak-down testing, and borescope inspection are performed to identify internal engine problems before major disassembly.
Precision Teardown & Machining:
Engine components are carefully disassembled, measured, cleaned, and inspected using precision tools. Cylinder heads can be resurfaced and critical components checked against factory specifications.
Torque-Angle Assembly & Testing:
Components are reassembled according to factory torque and angle specifications, followed by timing synchronization, oil-pressure priming, and final road testing.
