my dad taught me some of the most important things about wrenching when i was a kid. i remember watching him work on an old automatic toaster to fix the little spring mechanism that makes the bread pop up when its done. he took it apart on the kitchen table, on the previous days newspaper and taught me that if you learn how to take something apart really carefully you can always put it back together correctly. go slowly, take your time, think as you go. it's easy to get excited and rip things apart and wind up with a dizzying pile of parts. never trust your memory - take notes, take pictures, label things, keep them in piles of associated components.keep like fasteners together - in most cases they will serve the same purpose, and use an organizing system to keep track of where they came from (ziploc bags and a sharpie are perfect).look carefully at wear marks where one part meets another - this will give you clues as to how the parts go back together.think about what parts do - if you understand what a lock washer, compression washer, spacer, etc. does it makes it easier to know the order that these things go back on.a motor seems complicated as a whole, but when you break it down into systems it gets very logical. think of charging system, electrical accessories, ignition system, fuel system, lubrication, valve train, timing, etc. and it will make sense.ask questions, read up, get help when you feel that nagging doubt in your gut. when something doesn't seem right, it probably isn't. don't force parts together unless they're supposed to be, as in a press-fit component.when you're done and you have an "extra" part or two, never, ever throw it away and assume it's not needed. don't ask how i know this...the advantage you have with a spare engine is that you have no urgency since your car is currently running. if you don't rush you'll be fine. looking forward to the build thread!
