420A Weird noise by drivers side front wheel well

[Jonnychance]

I have no idea what this noise is but it's in the engine bay.
I have 420a motor and I can hear it clearly by the front drivers side wheel well, here's the sound:

it is.
With the hood popped does it sound like its coming from the engine or transmission?

You might wanna get a mechanics stethoscope from harbor freight, itll cost you like $4 and make it way easier to track down noises

Well it's coming from the right side so I would say the transmission, and alright I'll look at the stethoscope and do u remember if it was serious?

Manual

does the sound go away when you press the clutch pedal?

how about if you rev the engine up a couple times, does that make it go away?

 

[Jonnychance]

Well it goes away when I warms up, but I can check that tmrw morning or tonight

i think i remember what it sounds like.
My brother had a 3g with a 3.0L 6g74. It would make a sound like that when it was cold. If the engine was reved up a few times or idled for a few mins the sound went away. It took me forever to figure it out what it was. It was the timing tensioner.
you know how a clutch that needs to be bled, will stiffen up if you pump the shit out of the pedal? well the same basic thing was happening with the timing tensioner, once the engine was rev'd it pumped up the tensioner and it stiffened up

 

[Jonnychance]

Oh okay so is that something that really urgent to fix or can it wait till it gets warmer out?

 

[dustyboner]

i cant say thats for sure what it is. get a stethoscope from harbor freight so you can pinpoint where the noise is coming from

Other option would be a worn throwout bearing. After my car sat for a whole winter (and the fact it's a cheap bearing, probably) the TOB would make some horrendous noises and I was sure it was going to grenade. Then after it warmed up, no more noises. When it's cold it'll make noise for about 1 min, then stops and no mechanical issues.

Granted mine is a 4g63, but same concept.

Also, doesn't the 420a trans ( can't recall the model#, g350 or something...?) Have issues with the 5th gear nut loosening up? I thought I read somewhere that happens occasionally.. might pull the outer cover off and check if anything on the cluster is loose.

.... ( can't recall the model#, g350 or something...?)......

the tranny is made by New Venture Gear
so i think its nv-350 or nvt-350
