Verified Reviews for Engine Repair
★ ★ ★ ★ ★

“Scott did an excellent job from start to finish. This is what small business should look like. A quick chat to find out what the issues with the machine were and a handshake at the end of the interaction.

From initial phone call to set up having my snowblower fixed to picking it up in an exceptionally fast turn around time, this was a great experience.

I will happily return when I need servicing on my small engines and would highly recommend to anyone.”

“Dave and staff were very friendly, and professional from start to finish. We had a new furnace and AC unit installed, and at the same time relocated the furnace to a different area of the basement. They did all new ducting, bent in custom sizes for extra head room underneath. All the work was very nicely done, fit and finish are excellent. Wife and I are very happy with the products, work, and service.”

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
Visible oil or coolant leaks pooling under the vehicle

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 Thunder Bay? +
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.
