1997 2.3L 5 Speed Manual Transmission Ford Ranger contant Rattling?

Added (1). The rattling didn't really start until after my EGR valve went bad, which has now been replaced. However, I still have a rattling sound, when it starts up I feel like its going to die and when its idle it rattles as well. It has rattled when its been very cold before but that was it. Now the rattle is constant and I can feel my truck vibrate occasionally from it. I would like some help trying to figure out what this could be caused by

Bad motor or transmission mount

Fault might not actually be related to EGR but seems likely as started after working on it. Sounds as though a pipe? Feed to EGR is cracked or we have damaged /not correctly fitted it. A garage can easily overcheck work and more likely find source of noise as trained 'ears' and aware what to check. Bear in mind many noises do travel and not unknown for a rattle? To seem to be coming form one area in a vehicle yet be caused. By a fallout. Much further away .typicla would be exhaust fault such as broken bracket or a metal heat Shield touching etc
