mazda 6 2.2 sport - madza 6 engine failure under warranty - MikeyBan
I've a mazda 6 2010 without an engine too. I had the car 7 weeks when the oil light flickered on and off and after 3 miles I pulled over to dip the car for oil. It was full so I rang my mechanic who collected the car. He rang me an hour later to tell me there was serious engine damage. He dropped the sump to find the oil strainer blocked with carbon sludge and steel filings. The filings are from some major bearings somewhere in the engine. So what's the cause and who's fault is it? Either the injectors are leaking fuel into the engine, which in turn is mixing with the oil and changing the properties of the oil, it normally acts as a lubricant but also cools the engine. Now here is where I post an opinion of a former mazda technician who worked on many mazdas with this blocked sump strainer problem. Apparently when you get your car serviced with mazda they are told drop the sump and check the strainer as part of the service, this alone tells me that mazda know that there is a problem with there diesels. Every time the DPF filter regenerates it releases some diesel into the engine which again changes the oil and affects its properties, which means it can't keep the metal parts of the engine cool enough, so what happens with the heat and the friction is that the softest part of the engine gives way. This is usually the crank bearings, which is the metal filings that mix with the oil and finish up in the sump oil strainer. This in turn prevents the oil pump from picking up any oil which is a double whammy for the lubrication of the engine. This can cause failure of the engine and sometimes the turbo can also be seriously damaged.
