Okay - official cause from Mazda:
"#2 Rod exploded through the block."
They want complete oil change records (as a few of you said they would) or "they probably won't cover the warranty work." There's no possible way I can get records going back 2 years for oil changes I did myself.
The engine was detonating not 4 months ago. Is there any way I can get around the oil change records? I could TRY and get them but I highly doubt I can considering I bought oil anyplace that was handy.
Your reccomendations, guys? I *am* willing to goto court for this one.
