    This 2017 2.2 diesel of mine is a gem. At 7000 miles it is running like a Swiss watch and with zero oil consumption or dilution. They’ve got it right as far as I am concerned.

    The problem only shows up when mileage is high.
    I am with a forum of Mazda owners from another country that Mazda sell diesel vehicles.
    Owners complained about this issues after 3-4 yrs of ownership with higher mileage.
    Mazda mostly replaced their engines under warranty.
    1st sign they saw is oil level went up.
    Some owners had coolant all over the engine bay.
    Maybe that is part of the reasons why Mazda is delaying diesel vehicles in USA.
    They probably want to make sure diesel engines are reliable in USA, where reliability is very critical for buyers.

    The problem gets worse as diesel engines accrue mileage.
    The oil level goes up due to diesel getting in, that’s normal. If the oil went up due to coolant getting in it would turn it grey.

    The Diesel engine isn’t prone to these problems as you say.

    My car is a 2013 build . As other posts say the oil is diluted by the regen cycle from the get go not only on high mile cars . This was an issue with the diesel from new and a software update was done to help the issue . I do not know much about it as I never brought the car new . I still do not like the idea of diluted oil but it had nothing to do with my failure . At 140,000 km my oil goes from full to under the x between services , I have never had the level warning .

    This is more a symptom of how it is driven I believe , I do 70km a day on the highway . My work mate does 40km around town , he has had the over fill warning twice in the 35,000km he has had his .

    I did not get any coolant in the oil , from my diagnosis it blew the head gasket plan and simple , overpressured the radiator and blew all the water out the overflow . This results in coolant all over the engine bay as is gets blown over the engine driving down the road , matching the description above .
    Mazda confirmed it was a blown head gasket and fortunately for me the dealer said "Mazda are aware of a small number of faulty manufactured head gaskets , your car has the batch number identified . Mazda stand by there product so will be replacing your engine " . Good news for me , not so good for my work mate who has on a month older than mine with about the same km . He has no issues with his to date .

    Overall I am happy with the car , it could do with a little more ground clearance at the front lip as I keep catching it around the farms . I get 6.5 litres per 100 km out of it , and in this country that makes it cheaper to run than the suzuki swift we have . To be honest I dont think the car needs any more power , I have had diesels for a many years now and struggle to go back to a petrol car . Sure the swift sport is probably a quicker car if you keep the revs up (compared to a diesel) but it cant compare to the low down pull of the cx5 , its just an easier drive overall .

    I brought a high mile second hand car as I do high miles , in a year or so it will be at 250 to 300,000 km and I expect a throw away from a resale point of view . For the first time I am actually thinking of just trading it in for another one .

    Cheers
    Chris

    Not necessarily. The pressure in the pipe is down to the pressure cap and my 2017 spews water through the tank like that.

    OK, you didn’t give that information. If there are no leaks you may well have a problem.

    Yes it does look strange however, don’t do any more pulling parts because if they suspect you’ve been meddling they might withdraw from warranty.

    Very good photos.
