Engine mountings should produce more movement thus noise the moment the
engine starts pulling (or if auto when it is put in gear) and so on.
You have to come back with more info. Try to listen for noises with the hood
open (car stationary). If noise is only apparent when the car is in motion
then ... different problems.
If your chain is worn you are most likely to hear it with the car stationary,
hood open and rev it high and listen for noise on decelaration (a bad chain
will start slapping).
If noises are only apparent under load then (possibly bad news) engine
bearings may have problems.
On the good side of things you may just have overinflated tyres.
