Had the car been a tad older I would have said that your problem is down to a dodgy camshaft being fitted. My understanding is that the no vehicle in 2014 were fitted with the 'soft' camshafts - but who knows? It's worth getting the definitive answer from Mazda

There was nothing wrong with the camshafts it was the camfollowers that were too hard causing wear on the camshaft.

Sorry - there is no such thing as "Too Hard"

Thanks for the comments, appreciated. It appears that the DPF was 4/5ths blocked which caused the problem with diesel getting into the sump. This sort of system must be a design fault by Mazda, after all who would allow fuel to enter the lubrication system. Will be attempting to get money back from Mazda as the independent garage advised that it was likely to have been partially blocked when I bought the car. Will be difficult to prove but surely shouldn't be that blocked after 31k miles and 4 and a half years. In case anyone else gets a similar problem, this has cost in excess of £5k to sort out. New bottom engine block and new DPF!!!
