Broke the rod. The big end was still in place. One of the nuts was ripped off... but even the bearing hadn’t spun. Once I freed the twisted rod from the counterweight, it spun as normal.
Wondering if it was the RPM that caused it... 6200
My AF meter is on the fritz... reads sometimes. It’s been ongoing all year. On my third O2 sensor this year. So, I’ll replace the meter with an AEM unit.
Maybe it was a combination of being lean and the high revs?
Anyway, what’s done is done. So, not I need to decide whether I build another 250, use an Atlas, take up the offer of a BMW M50, or look towards a Barra or 2JZ.
