well i love working on cars
i like you craved to no the ins and outs , so as my first job i was a mechanic and i qualified all three levels so i no most things like cambelts and the things you mentioned
but after a 4 years of working in cold garages only a year after qualfying i had to pack it up due to suffering server dermititus althought using the nessecery hand balm ang glove
very sad to stop working on motors but i still indulge in my own car repaires in fact i done my cambelt wen i bought my car
advise the classes if you can find some place to do it
cheers
