Verified Reviews for Engine Repair
★ ★ ★ ★ ★

“Brought a head and cylinder from my ATV to Scott to see if the cylinder needed to be honed or bored out.

He took some time to look over the parts and said there was a possibility it could be honed, however he suggested it may make more sense to bore the cylinder and be 100% sure its good. He suggested a very reputable shop and even called on my behalf to discuss the proper course of action and sent me on my way.

That says everything about the character Scott is and that he is looking out for his customers. If I have a need for his services again I'll definitely go back!”

Common Causes of Auto Engine Problems

Neglected oil changes causing internal sludge buildup and bearing wear
Overheating due to coolant leaks, failed thermostats, or water pump failure
Worn or fouled spark plugs causing misfires and poor combustion
Timing belt or chain failure leading to catastrophic valve damage
Carbon buildup on intake valves reducing airflow and performance
Failing head gaskets allowing coolant and oil to mix internally

Critical Signs Your Auto Engine Needs Repair

Check Engine light is on or flashing on the dashboard
Engine is knocking, pinging, or making metallic rattling sounds
Significant loss of power during acceleration or climbing hills
Excessive white, blue, or black smoke from the exhaust tailpipe

Engine Repair Tips

Never ignore a flashing Check Engine light—it indicates active damage to the catalytic converter or engine internals
Follow the manufacturer's timing belt replacement interval exactly (usually 100,000 to 160,000 km)
Use the correct grade of engine oil specified in your owner's manual
Monitor your temperature gauge regularly, especially in heavy summer traffic
Address small oil leaks before they become major engine failures
Get a compression test done if your engine has over 200,000 km to assess internal wear

Frequently Asked Questions

How much does engine repair cost in Barrie? +
Minor repairs like spark plugs or sensors cost $150-$500. Head gasket replacement runs $1,500-$3,000. A complete engine rebuild costs $3,000-$6,000+, while a replacement engine with installation ranges from $4,000-$8,000+.
Is it worth rebuilding an engine vs. replacing it? +
If the block and heads are in good condition, a rebuild is often more cost-effective and can result in a like-new engine. If there's severe damage (cracked block, spun bearings), a remanufactured replacement may be more practical.
How long does an engine rebuild take? +
A complete engine rebuild typically takes 2 to 4 weeks, depending on parts availability, machining requirements, and the shop's workload.
What causes a head gasket to fail? +
The most common cause is engine overheating. When the engine exceeds its designed temperature, the head gasket material warps and fails, allowing coolant and oil to mix or leak externally.
