Spinny Evaluator Interview Questions, Process, and Tips for Experienced

Turbo is a device that increases the power output of an engine by forcing extra air into the combustion chamber.

• A turbocharger uses exhaust gases to spin a turbine, which in turn drives a compressor to force more air into the engine.

• The additional air allows more fuel to be burned, resulting in increased power and efficiency.

• Turbocharging is commonly used in automotive engines to improve performance.

• Examples of turboch...read more

Gear box overhaul can be identified through various signs and symptoms.

• Unusual noises or vibrations coming from the gear box

• Difficulty in shifting gears or gears slipping

• Leaking fluid or visible damage to the gear box

• Decreased performance or power

• Increased fuel consumption

• Warning lights or error codes related to the gear box

• Excessive heat or burning smell from the gear box

The connecting rod is a component in an engine that connects the piston to the crankshaft.

• The connecting rod is located inside the engine block.

• It connects the piston to the crankshaft, transferring the linear motion of the piston into rotational motion of the crankshaft.

• In a typical four-stroke internal combustion engine, each cylinder has a connecting rod.

• The connecting rod is usually made of steel or aluminum alloy.

• ...read more

To identify a misfired car, look for symptoms such as rough idling, decreased engine power, and unusual exhaust emissions.

• Listen for a rough or uneven engine idle.

• Notice a decrease in engine power or acceleration.

• Observe unusual exhaust emissions, such as black smoke or a strong smell of fuel.

• Check for a flashing check engine light on the dashboard.

• Perform a diagnostic scan using an OBD-II scanner to retrieve error cod...read more

Pillars can be damaged due to various reasons. Identifying damage involves visual inspection, checking for cracks, leaning, or other signs of instability.

• Inspect the pillars for visible cracks or fractures.

• Check if the pillars are leaning or tilting.

• Look for signs of water damage or erosion.

• Examine the pillars for any signs of structural weakness or deterioration.

• Consider conducting a professional assessment or using s...read more

The plug is typically attached to an electrical outlet.

• The plug is usually connected to a wall socket or power strip.

• In some cases, the plug may be attached to a power cord or extension cord.

• The plug can be found in various locations depending on the specific device or appliance.

• Examples include plugs on the back of a computer tower, the side of a television, or the bottom of a lamp.

Engine overhaul can be identified by various signs such as reduced performance, increased oil consumption, and abnormal noises.

• Reduced engine performance

• Increased oil consumption

• Abnormal noises such as knocking or ticking

• Excessive smoke from the exhaust

• Metal shavings in the oil

• Loss of power or acceleration

• Difficulty starting the engine

• Poor fuel economy

To check the tyre year and manufacturing, look for the DOT code on the sidewall of the tyre.

• The DOT code is a combination of numbers and letters usually located on the sidewall of the tyre.

• The last four digits of the DOT code indicate the week and year of manufacture.

• For example, if the last four digits are '2318', it means the tyre was manufactured in the 23rd week of 2018.

To check engine back compression, perform a compression test using a compression gauge.

• Connect the compression gauge to the spark plug hole of each cylinder.

• Disable the ignition system and fuel system to prevent the engine from starting.

• Crank the engine several times and record the compression reading for each cylinder.

• Compare the compression readings to the manufacturer's specifications.

• Low compression readings may in...read more

Black smoke indicates burning oil, white smoke indicates coolant leak, blue smoke indicates burning oil.

• Black smoke is usually caused by burning oil, which can be a sign of engine problems.

• White smoke is often caused by a coolant leak, which can indicate a blown head gasket or cracked engine block.

• Blue smoke is typically caused by burning oil, which can be a sign of worn piston rings or valve seals.
