Oh, so it isn't done, but it isn't much your problem to deal with? I can smoke to that... :]Two pieces, ROFLMAO. Right now it looks more like someone set off a bomb in my side yard. You have to transfer many of the pieces from the old engine onto the new engine after washing them, of course. New gaskets for all those new parts etc.... It takes about a week to do an engine if you take your time. I've seen it done in 12 hours but those were with a couple people of my husband and raratt's skill level. I'm only useful because I'm the hoist whisperer.
