	First thing to do is strip the engine down to its pants leaving just the engine block. Be sure to number the rods and pistons and place a little marker on them showing what direction they were removed from the block. '''It is absolutely critical that reassembly is the exact reverse of how they were removed'''. You must mark the pistons the rods and the bearing caps. I put numbers and arrows with a paint marker so there can be no confusion.		First thing to do is strip the engine down to its pants leaving just the engine block.
