Mckie, Interesting things you find inside a factory built engine when building a race engine

Always check your engine block & bearing are clean before assembly, I found this bearing damage when stripping my standard factory built engine, preparing for a race build.

Wow that's a perfect example of why you should keep your engine clean while building it!

The soft coating protected the cranks, no damage

Just a small speck behind the bearing can make a big impact
