3/14/2023 0 Comments Mazda 6 mps![]() ![]() Is it something you should worry about? Yes and no. In one of these papers I saw, one of the proposed prevention methods was to introduce a raised crown on the piston which seems to have worked because I have definitely not heard of a single stock MK2 going pop, both in the US and in the UK. The MK2 3 MPS actually has revised piston heads which I and others suspect is to try and prevent LSPI events occuring. There's a few papers available online of studies into LSPI, quite a good read actually. ![]() Again, these LSPI events can be linked to the attributes above or simply due to the inherent flaws associated with a direct injection turbocharged petrol engine. The Mazdaspeed forums seem to indicate that the majority of ZZB's are indeed linked to low speed pre ignition events, with some causing instant failure whereas other engines may have actually carried on functioning with a bent rod for a few thousand miles before finally letting go. I accept I could be wrong, and if I am then fair enough, and I also accept you probably have more knowledge on the number of zoom zoom booms in the UK through the MPSOC FB page which I am not part of (yet). The rest of the MPS' that i've heard go pop can be attributed to modifications/poor driving/poor maintenance or multiple of these points. I know of only a single stock mk1 MPS in the UK going pop due to the owners' wife flooring it in 5th while doing 30mph. I disagree with the statement "so many go pop". ![]()
