Why does the author suggest DIY car enthusiasts should own dial bore gauges and micrometers?

• To impress professional mechanics

• To have actual insight into the engine condition

• To save money on engine rebuilds

• To start a machine shop business

What indicates that an engine has passed visual inspection during bore examination?

• Oil leaks in the bore

• Rust in the cylinder

• Absence of damage and presence of honing marks

• Deep scratches and scoring

What is the purpose of zeroing the micrometer before measuring bore dimensions?

• To distort its shape

• To prevent accurate measurements

• To align the zero mark with the correct measurement

• To increase the bore size

What does an out of round condition in cylinder bores indicate?

• Presence of honing marks

• Difference between trust and non-trust axis dimensions

• Even wear across the bore

• 42 millimeters from the skirt bottom

• Close to the piston head

• At the bottom of the skirt

What is the formula for determining the new bore size when using oversized pistons?
