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. We'll email you quotes for an inspection within 2 working days, and where possible provide an indication as to the likely underlying issue(s) and cost to fix. You can book directly on the My Auto Shop platform in minutes.

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 vehicle jerks forward at high speeds its often as a result of a:

  • Failing Mass Airflow Sensor
  • Engine Vacuum Leak
  • Fuel Pump Malfunction

Popular services linked to a Engine Inspection:

Idler Pulley Replacement

The idler pulley is a component that doesn’t power anything but it makes sure that things can be powered correctly. Your drive belts power things like power steering, alternators, water pumps etc. The idler pulley makes sure that all of these can be powered as they should and that all the required belts stay where they should.

Cambelt Replacement

Also known as a “timing belt” the cambelt ensures the engine values open and close at the correct time by ensuring the camshaft and crankshaft in the engine remain aligned. The belt, made from reinforced rubber, is tensioned between a series of pulleys and tensioners, making sure that the belt does not slip and that it remains aligned, for optimum engine performance. Some vehicles have a timing chain that replaces the cambelt. Timing chains are more reliable and therefore need replacing less often, but are more complicated to replace if they become damaged.

Drive Belt Replacement

Also known as the “V belt” (or serpentine belt), the drive belt transfers “drive” to your air conditioning, alternator and power steering while the engine is going. Many cars have multiple drive belts, depending on the number of accessories fitted to the vehicle’s engine, and these belts are connected to the crankshaft pulley, which turns the belt creating power. As the belt drives the alternator (amongst other things), which in turn charges the vehicle’s battery, the drive belt plays a critical role in the function of your engine.

Oil Pan/ Sump Gasket Replacement

Have you ever cleaned your garage, only to find pesky oil stains on your floor the next day? This is usually the fault of the gaskets in your engine. Your sump holds nearly all of your oil in the engine when your car is off. If your sump gasket is playing up then more often than not, it can lead to annoying leaks that can sometimes lead to more issues.
