My engine is getting rebuilt right now with a new crank and bearings. Everything else checked out fine.
I would stay away from a used engine because you don't know how the previous owner treated it. If you can afford it, I would just get it rebuilt. That way, you know that you have a sort of 0 mileage engine under the hood again. Food for thought.
My damage to my wallet here in Germany is close to 8K euros ($9100). Compared to a new engine here in Germany that run for almost 15K euros and that is just the head and block.

What type of internals did you use on the rebuild. I have zero mechanic experience, but at these prices, I may have to grab some tools and go to town. I have nothing to lose at this point. I want to remove the oil pan and see what type of damage I have before I go forward, but I have to remove a subframe and I'm just afraid!
Looking at other forums, there are a lot of people having issues with rods and bearings...from stock to modified engines. My gut feeling is that there will be a class action down the road, there has to be!
