Reman engine only made it 300KM, must be a record
My R3's reman made it a solid 300KM before it misfired and made a bang noise. Assuming an apex seal went. Mazda was not pleased, they're getting another one but have said that my BHR ignition has to stay off from now on.

or you can re-install and take your chances ...
btw, they aren't blaming anything, otherwise you would not be getting a new engine with a request not to install it. They don't want to chance it is all.

Gosh G man, it's frustrating. Honestly keeps me up at night cause i'm searching the forums trying to piece together reasons as to what went wrong.
It doesn't help that I was supposed to drive home from university next week. So that'll be delayed until i'm no longer stranded.
I'm curious, would bad coils cause spontaneous engine failure? It was running great for the 300KM till the reman died. Starting on first crank, no misfires till the one that did the motor in ect.
Also thanks for all the responses guys. hopefully everything will work out.

Get the fuel pump tested. I know of a faster failure, about 3 miles. Lean spike from fuel pump failure killed the original engine and then the reman on the shakedown drive. Replaced the pump, no more problems.

I just put in a brand new S2 pump. It was originally what I thought was the problem but it ended up being the first engine failure.
Aston, it just really bothers me not knowing. If I could say for sure that the failure was just random and attributed to poor reman assembly that would be great. But I will always question if it was something that I did wrong.
Ok another question. I have an OBD2, is there things can I monitor besides coolant temp that I should keep an eye on with the next reman as warnings?

Hmmmmm... Seems like were all stumped.
It can't help much living in Canada. It's a bummer that it's an S2 engine also... From what I have heard, it's supposed to be pretty reliable.
Lets hope Mazda fixes this mess.

The ignition could have been a contributing factor but perhaps not enough to cause the engine to fail abruptly. If it were running too rich and with low compression and a misfire took place there is a slight possibility cracking an apex or side seal. I would lean more towards faulty assembly.
Did you compression test the engine at all before hauling it into the dealer? Would it just crank without starting? Was the engine flooded? things you could have checked to set your mind at ease. You can diagnose a bad engine with a simple compression test. Mazda should no doubt verify the crank no start issue before replacing the engine.
Unless you were beating the dog snot out of the new engine, running too low of an octane gas, with weak coils or a weak fuel pump the engine should not have went bad by any other means than a poor reassembly.

Mazdaverx7,
Thanks for the input. No compression test before towing it to the dealer however they did one there and rotor 1 was toast. It would still start, but definitely sounded like it was running on a single rotor.
I was breaking in the engine for those 300KM all under 4k RPM as well as monitoring coolant temps to make sure they did not exceed 200F.
It was weird because the reman seemed to be running pretty well. It would start on literally the first crank. And that was for both the OEM coils and when I swapped my BHR kit back on.

Mazda is taking their sweet time. When I called yesterday they still hadn't put in a request for approval to Mazda...They said they'd to it today. I'm guessing i'll have her back at the soonest next Wednesday.
I was supposed to leave tomorrow to go back home to Calgary :/
My plan is to take a few days to drive around when I get her back to break the engine in and make sure she's running alright. I'm afraid of something happening on the drive back to Calgary
Just heard this from the dealership
I sent off our findings to Mazda and they've asked us to remove and inspect the oil feed tubes from metering pump and oil injectors for blockage. Naturally they are concerned & suspicious why an engine would fail in 300km. So we'll be getting back on that this afternoon.
Not sure what to think
