Default Rod Bearing Failure Nightmares/Stories (One thread to rule them all)

There are tons of rod bearing failure threads around but I think it's worth having a single thread documenting everyone's failure/rebuild stories.

I'd like to see the following

year/model and mileage of failure
what caused the failure
how the rebuild was done
what was swapped/replaced
how long the car has lasted since the rebuild

I have a 2005 wrx that spun a rod bearing at 94k miles

I was getting it dyno tuned when the failure took place

I had the entire longblock replaced with an EJ255 from a 2005 Legacy gt that had a bad ring-land, the rebuilt longblock included weisco pistons and ACL bearings.

The shop that built the new engine re-used the original oil-cooler and oil pan/pickup tube but just cleaned them out. I didn't know this at the time, this was before I knew this shop cut corners and what to look for myself. The shop also used ACL Bearings and matched to OEM clearances and tolerances. They claim to blueprint everything, I asked for the final specs of all of the components but they didn't have any of that on record of course.

The new engine only lasted 18k miles over 1.5 years before spinning a bearing.

I'm looking to rebuild...again with a new shortblock this time, replace all oil recepticales with new - oil pan, oil cooler, oil pump, AVCS/Turbo Oil Feed Lines and I'm going to use ACL race bearings.

Who else has nightmares about this? What have you done and what has worked for you to keep the build on the road?
