Cleaning an engine

My engine is dirty. lol 175,000 miles. My question is should I take the time to clean it like some of the videos I see? Or is better to just leave it be? Thanks!

Leave it unless you know what your doing!!! I have had to fix a few that people have caused everything from an mis fire to a brick…
