Hi!

My engine overheated and immediately I shut it down. It is a 2.7 liter six cylinder. Was told I need new head gaskets. Now told that it locked up. How long does it take to install a used engine. Is it 20 hours as I have been told?

Yes, it should take 20hrs.. maybe more. Anytime I do anything that involves taking out the engine, I give myself at least 3 days to complete the task. That's because I'd rather take my time and get it right the first time and not have to fix the stupid little mistakes made because I wanted to rush.
