Hey, I'm late to the party, but here's my input. Hope it helps a little.
I always get these four from 
TNO in his tomb. I didn't even know they could be gotten elsewhere.
# NAM151B: "Aaagh. Worse than last time." -> After 
TNO resurrection. Engine.
# NAM152B: "Feels like I've been through a shredder." -> After 
TNO resurrection. Engine.
# NAM153: "Urf. Ugh. Feels like I've been strained through someone's bowels." -> After 
TNO resurrection. Engine.
# NAM154: "Oooh. Feel all stiff." -> After 
TNO resurrection. Engine.
I've heard Morte say all of these. I'm pretty sure it was only when Morte was the only party member AND 
TNO woke up in the mortuary.
# MRT397A: "Whoa, thought we lost you for good this time, chief." -> After 
TNO resurrection. Engine.
# MRT398B: "Looks like beauty sleep hasn't helped you any." -> After 
TNO resurrection. Engine.
# MRT400A: "Welcome back, chief." -> After 
TNO resurrection. Engine.
# MRT401D: "You know, I was just sitting here wondering whether you were going to get up, and then you have to go spoil my fun." -> After 
TNO resurrection. Engine.
# MRT402C: "Oh finally, now I can stop watching over you and go relieve myself." -> After 
TNO resurrection. Engine.
# MRT403A: "You know chief, you snore. Really loud." -> After 
TNO resurrection. Engine.
# MRT404C: "I'm sick of dragging your corpse back here with my teeth." -> After 
TNO resurrection. Engine.
# MRT405A: "I'm really sick of you dying on us. Cut it out, will ya?" -> After 
TNO resurrection. Engine.
# MRT406A: "I hope you have all your memories this time." -> After 
TNO resurrection. Engine.
# MRT407A: "I hope you haven't forgotten yourself, I don't want to explain our boring adventures all over again." -> After 
TNO resurrection. Engine.
