What kind of oil do you use on the bores to prevent them from rusting?


After washing the block, I sprayed them with WD-40, then they always get a little assembly lube that drips into them during the crankshaft installation - I wiped out the bores with a paper towel, but that lube residue sorta fills the honing marks. After I install the rings on the pistons, I dip the piston tops into a coffee can of 10W-30 (up to the rings) to help with ring compression and lubrication.... then install the pistons and leave the extra oil that you see in the bores. It'll all burn off on the first couple of revolutions after it fires. The bores aren't really as shiny as the oil and light make them appear.

Charlie, I didn't see anything wrong with the edge finish, but maybe I'm missing something. There were no burrs or flashing, if that's what you meant.
