Gunshipgunner...I certainly wasn't meaning to imply that your post was inaccurate or that engines don't need running in. They do, and what you'd written covered it quite well as far as the piston/liner goes. I was merely pointing out that one thing that's generally overlooked is the necessity of running in the con rod as well and so I used the quote from Jett Engineering as an acknowledged expert in the field. However, in the interests of brevity I only quoted the relevant part to correct your statement that the lower end doesn't need running in.
Let's not have a bad hair day over this
