I gave the bores a good clean up with a bore hone and this gave a good surface (deglazed) for the new rings to bed in. I flipped over the block and cleaned the inside of any debris or dirty oil. I vacuumed and blew it all out to make sure it was as clean as possible. After that, I lubricated the main bearings and shells with clean engine oil to give a little protection on startup. After fitting the shells, I installed the new thrust washers, lubricated everything again and dropped in the crank. I fitted the bearing caps and torqued them down incrementally until full torque was applied. I kept spinning the crank at every stage and thankfully it was silky smooth all the way through to final torque. I then fitted the oil pump, vacuum pump and oil filter housing to complete today’s tasks
