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.

Popular services linked to a Engine Inspection:

Fuel Pump Replacement

In order to get fuel from your fuel tank to your engine, your car uses a fuel pump. The fuel pump is either mechanical - run off the engine or electric - run off electricity. Some fuel pumps are located inside or very close to the tank. Others are located in the engine bay or attached to the engine itself. Without the fuel pump, your car won’t work.

Exhaust Manifold Gasket Replacement

You don't want your engine's exhaust pouring into your car. The exhaust manifold connects to your exhaust pipe, carrying gases towards the muffler until they exit via the tailpipe. It is the main gasket that seals and pressurises the entire exhaust system. Gaskets are used to seal gaps between two different surfaces. The surface where the exhaust manifold meets the engines parts must be sealed - this is what the Exhaust Manifold Gasket does.

Distributor Rotor Button & Cap Replacement

Back in the old days, instead of an engine computer telling your spark plugs when to fire, it was the distributor. These were phased out over the 1990’s to 2000’s period. If you have a car that still uses a distributor then it must be a classic - good for you!

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.
