This is a great how-to video and it is an illustration of the steps that dedicated engine builders take when assembling engines. It is not just about bolting stuff together and praying that it works, it is about putting in the leg work to make sure that things will not only fit right but also work to their maximum potential. This video that shows how to Measure Piston To Bore Clearance is invaluable to anyone building an engine right now or getting ready to assemble one. Why? Proper piston to bore clearance is essential to performance an engine longevity.
You don’t want too much room in the bore or the piston will rock and slap with consequences that you don’t need to be a rocket scientist to figure out. On the other side, a lack of clearance you won’t have the oil film you need on the bore and you’ll ultimately have a piston that tries to seize itself in the bore. Things will scuff and ultimately material will be ripped from the piston and cylinder walls leading to your tears, an empty wallet, and a busted hot rod.
Watch this video an the next time you are sticking an engine together remember the steps and the process used here. It is not rocket science but it could be vitally important to both your mental and financial health the next time you build a motor. This is truly great stuff!
