So, to bring it 'on topic' I can tell you all of the 2nd yr mech engineering student that came to us for some 'hands on' experience as suggested and organised by his mum. The guy is 22 and been at uni for a few years before his dad suggested, as he is keen on cars, to do mech eng.
His very first question to me was-how does a 4 cycle engine work?-I thought ahhh....trick question, but no , he was serious!!
Over the couple of days he had with us I eventually got around to telling him-that the reason I had to remove the distributor from the engine to replace the engine mount was because some dip-stick, sitting at a desk, decided it would be at good idea to add an hour to a 10 minute job.
This(only one example) is happening more and more in the newer models and can really cock up what should be a simple task.
I still don;t know if he knew what I was talking about to this day.....
