True you don't know if anyone replaced before. But I agree that it's unlikely (if that engine is original @105k) that they were replaced already with that wear showing.Originally posted by nsa View Post'06 car, 105k miles on the odometer. Rod bearing history is unknown, I assume they are the originals.

My 2004 Vert at 135000km / 83000 miles - I am the third owner having picked it up in 2012 and there is no doubt my car was treated like crap prior to my ownership. The number of half assed repairs and simply wrong things I had to correct in the first 3 years of owership was nuts.
Number 5 definitely spun at least once, given the witness marks on the back of the bearing. Near as I can figure, the tangs kept it from spinning more than a few times since they're still intact. I got incredibly lucky twice: first, that I didn't grenade the entire engine, and second, that nothing blew up after I completely missed those witness marks, threw new OEM bearings in, and buttoned it back up.
Since then, I've put 20,000 km (13,000 miles) on the car and while the very first oil analysis after the replacement showed elevated Copper(12ppm) and Lead(19ppm), the last three reports have come back clean with nothing in the filter and no cold start knocking.
