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 engine oil is black and gritty its often as a result of a:

  • Dirty Oil Filter
  • Normal Wear and Tear
  • Overdue Oil Change

Popular services linked to a Engine Inspection:

Water Pump Replacement

When your engine is running it can get very hot. To prevent the engine overheating, the water pump does what its name suggests. Pumping water around the engine and then carrying the hot water to the radiator where it is cooled and then pumped back through the engine.

Fuel Pressure Regulator Replacement

To pump fuel from your gas tank to your engine, your car has a fuel pump. In order to make sure that your fuel pump sends the right pressure fuel to the engine, your car has a fuel pressure regulator. When it plays up, your car can get too much or too little fuel and this can cause issues with your driving.

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.

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.
