When removing an engine with a hoist and it slowly becomes harder to operate the jack, check to make sure the dipstick tube is not hung and is now bent at a 90 deg angle.

Also, if you are assembling the bottom end of you engine and your kids are arguing outside your shop, ignore them. Because if you go out there, you might leave one connecting rod un-torqued and that might lead to a turned bearing and cracked cylinder wall, which might lead to a sleeve being installed, which might lead to said sleeve failing, which might lead to total motor destruction, which might lead you to sell the entire project car and get a different one altogether.
