Jay’s Tech Tips – How to avoid “Crank Walk”

Tech Tip – Shown on a crank that has just been washed and not polished.. The oil passages on most crankshafts are plugged at the factory as they are diagonal drilled. These passages will acquire trash/debris during the service life of the engine. If the engine has lost/spun a rod bearing there will be even more debris. Bend the straw on the brake clean and flush out this passage that centrifugal force has filled with junk! It will help get all the contaminate out that would have/could damage your new build. Most machine shops will not do this step so always check it. It’s a 20 minute process that could save you a lot of money.
