Verified Reviews for Engine Repair
★ ★ ★ ★ ★

“I was turned down by multiple "exhaust" and "custom exhaust" shops in town. Made appointments to be turned away... Globe run took me in right away and did exactly what I asked no problems. In and out within a half hour. Got my exhaust tail pipes welded on and work great. Thanks to Globe Run my car will be able to get the safety done now. When other shops turned us away for days”

“I had a great experience at Globe Exhaust in Oshawa. The team was incredibly friendly and easy to deal with from start to finish. They took the time to explain everything clearly and made sure I felt comfortable with the work being done.

The pricing was very reasonable, especially considering the quality of service. It’s not always easy to find a shop that’s both trustworthy and affordable, but they really delivered on both.

I highly recommend Globe Exhaust to anyone looking for honest, reliable service. I’ll definitely be coming back in the future.”

Engine Repair Tips for Oshawa Drivers

Change engine oil on time; clean oil is the cheapest insurance against timing chain and bearing failure
Replace your timing belt at the exact mileage or age interval in your manual (usually 100,000 to 160,000 km)
Shut the engine off immediately if it overheats or the red low-oil-pressure light comes on
Fix valve cover and oil filter housing leaks early before dripping oil ruins alternator windings or rubber coolant hoses
Ask for a compression and leak-down test report before deciding between repairing an engine or replacing it

Frequently Asked Questions

How much does engine repair cost in Oshawa? +
In Oshawa, ignition tune-ups, sensors, or valve cover gaskets typically cost $200 to $650. Timing belt or chain jobs range from $800 to $2,200, head gasket replacements run $1,800 to $3,500, and full engine replacements range from $4,000 to $8,500+.
What happens if a timing belt breaks while driving? +
Most modern engines are interference engines, meaning the pistons and open valves share the same space at different times. If the timing belt snaps, the pistons strike the valves immediately, causing severe internal engine damage.
Is it better to rebuild an engine or install a replacement engine? +
For minor top-end issues like a blown head gasket or worn timing components, repairing your current engine is usually best. If the lower block has spun a rod bearing or cracked, installing a remanufactured or tested low-kilometer engine is often faster and more economical.
Why does my engine rattle for two seconds on cold startup? +
A brief metallic rattle on cold startup is commonly caused by a worn hydraulic timing chain tensioner or variable valve timing (VVT) phaser waiting for oil pressure to build. Have a mechanic inspect it before the chain jumps timing.
