Loving the youtube 101 videos.
I sent Puff an embarrassing PM the other day where we went back and forward for what seemed like hours where he was slapping his head on the keyboard trying to tell me the pistons are offset. I would have sworn they wern't and had no idea what the hell he was going on about. Eventually I found out what that meant. Embarrassed? You bet!
For those that come across this thread in the future and you're screwing an engine together for the first time and have good mechanical aptitude but are just lacking in the engine assembly knowledge department, I can assure there are some little things that can bite you. Piston offset, piston ring top and bottom hardness differences (I.e. getting in the rhythm on the ring file for the top set then realise the bottom set are way softer!), not sealing certain bolts are some just to name a few.
I came across this series of videos. He goes into extreme detail, example 30mins just to show how to place a crankshaft into the block. A little long in places but overall perfect for those starting out. A recommended watch.
