Is Re-honing A Used Engine Worth It? Watch Me Find Out!

After a few comments hassling me about not re-honing a used engine while installing new pistons, well I decided to find out the truth myself. I use different methods along with just leaving the stock 300,000 mile engine bores while installing new pistons and rings, then drive it long enough for break in, then check compressions to find out the differences. I explain towards the end my main reason for doing this video. Hope this learns you something as it did me!
