Here is the work I do on Fridays as my work experience.
I changed the head gasket on a subaru legacy. I was able to use the hydraulic lift to lift a second car up and walk around underneath and remove the exhaust for removal of the engine.

Answers to Questions
What is the purpose of a glow plug? Cold starts on diesels, warms the air inside the cylinder.
What does B.D.T.C means ? Before Top Dead Centre, this is about 5% - 16% before top dead centre
When the piston travel at T.D.C and both valves are close, what stroke is it? compression
How many time the camshaft turns in a 4 stroke cycle? 1 time
What is the purpose of thrust washers? any object spinning in a clockwise direction has a tendency to drive forward, the thrust washers allow the crank to spin without driving forward.
Name all the components of the valve assembly? valve, valve spring, collet, seals, retainer shield.
What is the purpose of the tag on the bearing shells? this stops the shells from spinning around the bearing, allows oil to flow through the little holes.
What compresses the volume of air and fuel? piston crown
Why is it important to time you engine up correctly? The piston could come up an hit one of the valves and break the valve. rough idle
What is a stroke? when the piston travels between BDC and TDC and vica versa
What drives the cams? camshaft, cambelt
What is the block made of? cast iron
Why is core plug fitted?
What is the purpose of the pistons? compress the air and fuel mixture and then when those get ignite the explosion force pushes down on the piston crown which goes down and turns the crankshaft.
What is the advantages of having aluminium head? better heat distribution, light weight.
