i blew my motor today and i don't know why it blew. It was a 98 w/83000mi with just a intake and muffler. I'll admit i was driving a bit hard in the mountains, but nothing outragous. It had the right amount of oil in it , and everything else seemed to be ok. I was in the middle of a long tight left turn up around 6500rpm's and it started knocking. I pulled over to check it out. I realised something was very wrong so i tried to nurse it down the mountain but i was creeping up the last hill when it oil and smoke went everywhere. My rod from my #3 was sticking through the block smiling up at me. What caused this can anyone tell me??
