Seems like we went through this topic about a year ago with much heated
discussion on the merits of breaking in an engine or just driving it. John
Twist says that when they rebuild an engine they give no break in

wanting to take any chances I figure what the hey might as well do it by
the book. Now what do all of you thing about towing a car without
disconnecting the drive shaft....just kidding, REALLY!
