Well.... I am fu#&ed!!
I finally got some time to get down to turn the crank and #3 was so loose I could jiggle it around with the rod bolts tight. That bearing spun enough to eat up a lot of metal on the rod and scar up the crank. I am sure some of that nasty metal got to the crank main bearings as well since every bearing in this motor seems to show some damage. The one thing this shares in common with my N54 rebuild last year is that once again it is cylinder #3 that is bad. The N54 had a bent rod and this one spun the bearing on #3. In the future #3 is the go to cylinder I will be looking at for any N54/N55 engine.
Now for what to do....? I am confident I can rebuild this but where I will be to find a N55 crank is a mystery to me. There seem to be none for sale for a decent price. I am so temped to put my N54 into this car but God only knows what coding and rewiring that would involve.
