Disassembled the engine block and ordered new rod and thrust bearings. Tried to order main bearings and piston rings, but they are discontinued from Mercedes :( Rockauto said that they had 1 last set in stock and they were the wrong ones, so I'm reusing them. They still look brand new! I did buy a Lisle 15000 honing tool to lap the cylinders :) Mercedes used to layer silicone between the aluminum cylinders and the pistons in some of their blocks known as Alusil. That's right, no sleeves at all! I'm lapping the cylinders with Sunnen AN-30 and honing oil at home, then getting decked at the machine shop. Pics to come!
