My father made the mistake on a Perkin's Diesel, several years ago and didn't plastigage the crank before he installed it. He sourced the crank from a company he's been using for years, so he trusted it. Well anyhow, you guys can figure out the end outcome. It was a very costly mistake. Upon inspection, it seemed as though the machine shop may have changed stones in the middle of the project and never reset their machine. Bottom line, don't trust anyone! Always check!
