An engine that is properly maintained with regular oil and filter changes, changing the spark plugs, timing belt and coolant at specified intervals, etc., should last 100,000 to 150,000 miles or more. But many engines are not properly maintained. Oil and filter changes are put off too long. The coolant is never changed. Nobody remembers to replace the timing belt. Consequently, after thousands of miles of neglect, the engine falters or suffers a variety of fatal ills. It starts to burn oil. It fouls spark plugs and misfires. It burns a valve. It overheats. It blows a head gasket. The head cracks. The oil pressure drops dangerously low. Warning lights come on. It makes rapping, clattering, ticking noises. It is hard to start. It seizes up and refuses to run.

Engine work

At Mitchell's Garage we undertake all types of engine work, large and small including:
- Engine repair
- Engine replacement
- Engine modification and tuning

Engine Repair

Each repair we carry out is done using the best methods and equipment available. Our mechanics are highly trained to diagnose and repair most faults to the highest standard.

Due to the frequent use of a car`s engine and the amount of wear and tear that a vehicle's engine can go through, many faults can arise over time and cause problems. These may include:
- Starter motor
- Engine bearings
- Cylinder misfires
- Engine overheating
- Faulty ignition timing
- Intake manifold

Engine Replacement

Replacing an engine with a new, remanufactured engine or rebuilt engine can add years to a vehicle's life and save thousands of pounds over what it might cost to buy another vehicle.

Engine Modification and Tuning

We can imporve the overall handling and performance of your car. Car engine tuning is the process of keeping a car’s engine running as close to perfectly as possible. There are two basic types of car engine tuning. The first is stock tuning and the second is high performance tuning. Stock tuning is the kind of tuning that you will see at the dealership, with various engine parameters set to specifications that the manufacturer has decreed to be optimal. Performance tuning goes one step further and modifies the manufacturer’s specification to enhance the performance capabilities of the engine. Ignition timing, air-fuel ratios and spark plug gaps are just a few items that can be changed in performance tuning.

Please contact us if you have any questions or if you would like to book your vehicle in.


Major Engine Components

Spark Plugs
The job of the spark plug is to ignite the air/fuel mixture so that the internal combustion system starts.

Valves
Intake and exhaust valves are an important part of your engine. The intake valve allows air and fuel into the combustion chamber. After combustion, the resulting mixture moves through the engine and out of the exhaust valve. Both the intake and the exhaust valves are closed during the combustion process or igniting of the engine.

Cylinders and Pistons
The cylinder is the most important part of the engine along with the piston that floats in each cylinder. Most common are the four, six or eight cylinder engines. Pistons are round and move up and down inside each cylinder.

Piston Rings
Every vehicle has a piston ring for each piston inside the cylinder. These rings stop air and fuel from leaking into the engine's sump during the combustion process.

Connecting Rod

This rod connects the piston to the crankshaft and rotates at both ends during the combustion process.

Crankshaft
The crankshaft helps to turn the pistons up and down, similar to a wind-up toy, such as a jack-in-the box handle.

Sump
The sump completely covers the crankshaft and contains small amounts of oil to keep things flowing.
