Hi I just bought a 2006 Frontier SE (manual) with 130,000mi.
It's been babied by 2 previous owners (both over 50s-60s), complete with
all the maintenance and repair records since it came off the lot.
Rides like a new truck, lots of power, no leaks burning etc.
There are three noises I have began to notice (I did not notice them while test driving).
1) The first is rattle upon startup, and when I turn the truck off. You
know that distinct sound of a old large diesel motor when you turn it
off? That diesel rattle, mixed with a bit of exhaust rattle noise, is
what I hear upon starting/shutting off the truck.
2) The second noise is what sounds like ticking lifters, that are barely
perceptible on idle and that peak around 2000rpms. If I stay under
2000rpms and somewhat under-rev the truck, I can't really hear them
(they are still there, just pretty muted).
3) The third is a erratic, clunking, thunking, thudding, that seems to
show itself upon startup and once in a while on idle. It is almost like
someone is taking a rubber mallet and hitting something low and far back
in the engine compartment. I can feel this better than I can hear it,
through the stick shift while I am in neutral, just with my hand on the
stick. It is erratic, and not consistent with a random pattern. At
first, it sounded like I had the ebrake on, and the truck was creeping
down a hill one 1/4in at a time.
Unfortunately, I did not find receipts for the timing chain/guides.
However, I can't really hear a whine.... there COULD be some extra noise
indicative of this, but I haven't heard any other nissan frontiers to
compare (and I'm new to the truck).

#1 the timing chains will rattle @ start-up = normal. If it
does it shutting off, check the clamps on the ex. shields-
replace as needed.
#2 W/O hearing it, also may be related to the timing chain.
Can you hear it while driving?
#3 Is it related to erratic idle? May want to have your
dealer clear the self learn control and perform an IAVL
procedure. Does it have a GENUINE NISSAN oil impregnated
air filter????????????

#2 Can hear while driving, see video 1 below
#3 See video 2 below
I am not sure about the air filter, but I'll take a look.
I took video of both issues.
The first video is of the ticking/rattling and some noise from the timing chain cover.
The second video is of the thudding/thumping (noise 3 I described above)
First video of ticking/rattling in case you are on mobile and can't see playlists:

Second video of thudding/thumping noise:

So today I pulled up close to a wall so I could hear #3
sound better. Anyone watch the original Absentminded Professor? With
the green flubber? Remember how his flying car sounded? lol
Anyways, sound immediately disappears when I depress the clutch.
HMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
That makes me think it is a problem with the.... I dunno. Any ideas? Is there a shaft that spins while in neutral?
Anyone have a listen to video #1 ? Any thoughts on that noise?

You need to remove the timing cover, sounds like the long
guide on the tensioner side has broke and slid down. With
the miles, I would replace all chains, tensioners /shoes
and guides. If sound #3 goes away w/ the clutch depressed,
you most likely have a bearing/bearings failing in the
trans. unless the noise can be isolated to the transfer
assy.
