Ahhh another mx engine camshaft failure, i am a daf mechanic myself based in leicester, whereabouts is ur garage/dealership? we have undertaken many of these camshaft issues, its either turbo gone, cam followe dropped valve or cam itself on these its never straight forwards hey. them mx engines are a smart bit of kit but they dont seem upto the job hey. and in relation to what somebody said about amount of oil they contain, good guess but you were a way out, they hold 36 litres of engine oil in total. bloody big things!
