Add my name to the list. I have never heard of anyone installing pistons/ring with NO oil. My method is similar to czar's. First the engine is washed completely with HOT water and soap, then rinsed and blown dry using dry filtered air. Then the cylinders and all gasket sealing surfaces are wiped with clean lint-free cloth, using lacquer thinner or rubbing alcohol. Then, dried again this time with a fresh, dry, lint-free cloth. Cylinders are coated with 30# oil, then the rings, wrist pins and piston skirts are liberally oiled with 30#. Upper bearing shell is installed and lubed with ASSEMBLY lube (NOT moly lube or white (fishing reel) grease), then the piston/rod assembly is slid into the cylinder using a quality tapered ring installation tool, protection on the rod bolts. Crank is rotated so that the rod pin is at BDC before the piston is installed, that way you have room to work.
My engines are also built in a clean environment and always at a consistant temperature of 68 to 70 degrees.
Works for me.
