Your engine is the most critical and most complex system in your vehicle. Small problems left untreated can become expensive failures. At 4 Aces Auto Centre, our certified technicians handle everything from routine engine tune-ups to complex car engine repair, always with a clear explanation and a written estimate before we start.
4 Aces Auto Centre in Peterborough provides complete engine repair and maintenance, including check engine light diagnosis, tune-ups, spark plug replacement, timing belt service, valve cover gaskets, oil seal repair, and cooling system repair. We service all makes and models, including European vehicles, and help drivers make informed decisions before approving repairs. Our engine services also cover electrical systems and sensor faults that affect how your engine runs.
Engine problems can develop gradually or appear suddenly. Having warning signs checked promptly can help limit further damage. Watch for:
Arrange an inspection if you notice these symptoms. Continuing to drive with a misfire or an overheating engine can cause further damage, including damage to the cylinder head, head gasket or catalytic converter in your exhaust system.
Our engine services include diagnosing and repairing misfires, oil leaks, cracked manifolds, timing belt problems and head gasket issues, as well as engine rebuilds. We identify the problem and explain the recommended work before you approve repairs.

Engine repair costs range widely, from a check engine light diagnosis to major repairs such as head gasket replacement. At 4 Aces Auto Centre, you receive a written estimate for every repair before work begins. No surprises.
We will give you a straight answer. We assess the repair cost, the engine’s overall condition, the vehicle’s value, and the likely lifespan of the repair. If the numbers do not make sense, we will tell you. If it is worth fixing, we will fix it properly.
Yes. Where appropriate, we can replace an engine with a used or remanufactured unit. We explain the available options and provide a written estimate so you can compare replacement with repairing or rebuilding your existing engine.
Repair time depends on the fault, the work required and parts availability. Smaller repairs generally take less time than timing component work, engine rebuilds or engine replacement. After assessing your vehicle, we will explain the expected timeframe alongside your written estimate.
Warranty coverage depends on the parts installed and the repair performed. Our team will explain the applicable terms, including any time or kilometre limits and exclusions, before you approve the work.
That orange warning light tells you that your engine’s computer has logged a fault code. It does not tell you exactly what is wrong, and it does not always mean the problem will go away on its own. Ignoring a check engine light can allow a small repair, such as a sensor replacement, to turn into a much more expensive issue, such as catalytic converter failure.
Common causes of a check engine light include:
At 4 Aces Auto Centre, we use a professional OBD-II scan tool to read fault codes stored in your vehicle’s computer. From there, we perform the additional live-data testing needed to confirm the root cause instead of simply clearing the code and hoping it does not return.
For faults involving other vehicle systems, our vehicle diagnostics service helps identify the source. A flashing check engine light can indicate a serious misfire. Pull over safely and contact the shop for guidance before continuing to drive.
A tune-up helps restore engine performance, improve fuel efficiency, and reduce the risk of avoidable repairs. Over time, ignition components wear down and fuel systems can become contaminated, causing rough starts, poor acceleration, and lower fuel economy.
A proper tune-up at 4 Aces Auto Centre may include:
Tune-up intervals vary by vehicle. Most vehicles benefit from service every 30,000 to 50,000 kilometres. Vehicles with iridium or platinum spark plugs may go 100,000 kilometres or more. We follow your manufacturer’s recommended schedule and help you understand what your vehicle actually needs.
Worn spark plugs can cause rough idling, slow acceleration, hard starting, and reduced fuel economy. At 4 Aces Auto Centre, we replace spark plugs with the correct type for your engine, whether copper, platinum, or iridium. Each spark plug is installed, gapped, and torqued to manufacturer specifications.
Signs you may need spark plug replacement include:
Timing components keep your engine running in proper sequence. When these parts wear out or fail, the result can be serious internal engine damage.
If your engine uses a timing belt, it has a manufacturer-specified replacement interval, often between 90,000 and 160,000 kilometres. A snapped timing belt on an interference engine can cause catastrophic internal damage, including bent valves, damaged pistons, or a destroyed engine.
When replacing a timing belt, we recommend servicing the complete kit, which may include the belt, tensioner, idler pulleys, and water pump where applicable.
Check your owner’s manual for your timing belt interval. If you do not know when your belt was last replaced and your vehicle has more than 100,000 kilometres, it is a good idea to have it inspected.
Engines with timing chains do not usually have a set replacement interval, but chains can stretch and guides can wear over time. Common signs of timing chain problems include rattling on cold startup, check engine codes such as P0008, P0009, or P0016, and increased oil consumption.
Early detection can help prevent major engine damage.
Oil leaks from the valve cover, camshaft seals, rear main seal, or timing cover are common as vehicles age. Left untreated, leaking oil can contaminate belts and hoses, create a fire risk, and cause engine damage.
Many leaks are first spotted during a routine oil change, which is one more reason to keep up with regular oil and filter service.
Some engine problems require more than replacing a single component. A failed head gasket, low compression, bearing damage or a broken timing belt may require a detailed assessment before an accurate estimate can be provided. Testing depends on the symptoms and may include compression testing, leak-down testing and checks for oil or coolant contamination.
After identifying the problem, we explain the available options and provide a written estimate. Depending on the damage, these may include a targeted repair, an engine rebuild or replacement with a used or remanufactured engine. We consider the repair cost alongside the age, kilometres, overall condition and value of your vehicle.
Before deciding whether to repair your engine or replace your vehicle, speak with our team. We will explain the findings so you can make an informed decision.
An overheating engine can warp cylinder heads and damage head gaskets in minutes. What starts as a simple thermostat issue can become a major repair if the vehicle continues to be driven while overheating.
At 4 Aces Auto Centre, we service the full cooling system, including:
If your temperature gauge rises above normal, pull over safely and call us. Continuing to drive an overheating vehicle can cause serious engine damage. For more information about radiator repairs, coolant maintenance and related work, see our transmission and cooling system services.
Engine repair costs vary depending on the vehicle, engine layout, parts required, and labour access. At 4 Aces Auto Centre, you receive a written estimate before work begins so you can make an informed decision.
