Simply leave as many details about the issue as you can and we will contact local MTA approved mechanics that are qualified to fix the underlying issue.

How a Engine Inspection works with My Auto Shop:

Our qualified mechanic will look to complete a thorough inspection of your vehicle's engine using the information or symptoms you have provided via the My Auto Shop platform. To complete this the mechanic will usually start by plugging into your OBDII port and completing a complete diagnostic scan. This will highlight any error or warning codes your vehicle has and will provide the mechanic with information they. need to fix your problem.

Depending on the symptoms the mechanic will take a good look at your vehicles:
- Drive & timing belts (cambelt, serpentine belts);
- Camshaft & crankshaft;
- Spark plugs; or
- Oil pan.

Before completing any repairs the mechanic will complete a quote and look for your approval.

When your hearing a bearing knock noise from your engine or exhaust its often as a result of a:

  • Worn connecting rod bearing
  • Excessive main bearing clearance

Popular services linked to a Engine Inspection:

Camshaft Position Sensor Replacement

Your engine computer needs to know when it’s time to send a spark through the spark plug, it does this with the information from the camshaft position sensor. The CPS tells the engine computer the exact right time to ignite the air/fuel mixture and makes sure your engine runs as flawlessly as possible.

Throttle Body Replacement

When running, your engine needs a certain amount of fuel and air to perform at its best. The fuel injectors take care of the fuel part, the throttle body takes care of the air part. The throttle body is connected to your accelerator by a wire or by a cable, it regulates how much air is let into the engine and therefore how quickly the car accelerates.

Catalytic Converter Removal & Replacement

While your engine is running it pumps out plenty of harmful exhaust fumes. To minimise this, car makers introduced catalytic converters to reduce the amount of CO2 and nasty pollutants entering the atmosphere.

Accelerator Cable Replacement

A lot of cars used to trust a steel cable to transmit inputs to the accelerator to the engine. Modern cars use a drive-by-wire system. Over time the cable will need adjusting as it stretches. In some rare cases, if you’re a real fast and furious driver, it can snap and require replacing.
