My engine log is incomplete and doesn't show the first 1000 hours or so from the time the plane was new. But it appears that the current engine is the original one, it has 7,000 hours on it, and has been overhauled at least three time......

On most 4-cyl light aircraft engines, by the time the engine has been overhauled 3 or 4 times, there is little if any of the "original" engine remaining. Most engine logbooks should be renamed "log of replaced engine components"..
