How many hours of run time does it take before a K5.9 big block needs to be rebuilt?

Define rebuilt?

Do you mean taken apart to clean/inspect and put back together with new rings and gaskets? If so then it depends on who does it. Would take me hours, while a pro would probably do this in under an hour...

A rebuild isn't something you can put a timeframe on. It can vary drastically. What does the compression feel like at top dead center?

Also, can you better describe how it isn't running well?
