Hello! I had a question about my 2008 grand marquis at 80k miles 4.6L I was wondering if I should and when should I change my timing chain on the car. Thanks.

Timing chains are good for the life of the engine, providing you do regular maintenance and don't drive it low on oil. They don't dry rot and crack like rubber timing belts. Running low on oil causes metal to metal wear on the chain and sprockets. If you don't maintain the engine and routinely check/ change the oil, you will eventually wear out the engine to a point where the timing chain is the least of your concern. Everything in the engine will be worn out.
