Why do engine gaskets go bad?

You have this strong thin material jammed tight between two blocks of metal. Is it pressure that eventually causes weaknesses/leakage?

Time, heat and not changing your oil enough. I can’t stress this enough. Hydrocarbons from your fuel attack the softeners in your gaskets and they harden. Hard gaskets can’t deform under thermal cycle so you end up with leaks.

It’s always easy to spot the neglected engines.
