Can also rub on the brake lines near the frame. Have you looked at all the pully's including the harmonic balancer at idle? I know you said it sounds like a tractor so I don't think it is it but are you familiar with the "type writer tick"?
I need some advice

I put the new boots on it and a water seperator since i broke a wire off of it the other day. I did the pcv re route since i was that deep and need the room to see while its running. It was dark when i finished so i started it hoping the noise was gone, no such luck. I will video it in the morning and post a link to it. Im tired of it but i now have 6 days off to figure it out. I did change the fuel filter the day before it started this. I used an acdelco. Any chance its defective and causing the noise?
I hooked up my ppe standard and found what says balance rates. I read that the option wasnt therw but thats what it said. The readings were in mm. On startup in park the following were read;
1. 0.6
2. 0.5
3. 1.0
4. 0.3
5. 1.7
6. 0.0
7. 0.0
8. 0.6
After running a few minutes this is what it was;
1. 0.2
2. 0.9
3. 1.0
4. 0.9
5. 1.7
6. 1.3
7. 0.8
8. 0.0
Fuel pressure was anywhere between 4700-5500psi.
I dont know if this tells anyone what i may be dealing with or not.

well those Balance rates look good. take your oil filler cap off with it idling and see how much blow by you have coming out. a cracked piston should show a up in the balance rates though.
And another. When i touch the throttle at all the noise is gone. Even 100 rpm over idle and its gone. Is it a dirty injector? http://youtu.be/k9J4cTqlQGs
Sound like its at the front of the engine? I had a cp3 do same violant shake at idle and give it fuel and go away. Don't know if the sound sounds like its at the front??? Otherwise I'd say flexplate
Pull that little cover on the drivers side of the bell housing out and see if the noise sounds like its come from there. also bar the engine over through that hole and inspect the flex plate and see if you can see any damage tot he flex plate. I had one bolt come loose on mine and it was make a noise nott his loud but similar. when i barred the engine over to check the flex plate i found the one bolt wasn't holding the flex plate tight to the convertor.
I hate it but i agree. Enough that i just got home from ordering one.The noise does seem like its coming from there. Using a stethoscope it seems the noise is loudest there too. I dont have a way to do a cutout test. Now when it starts and when the truck is shut off it makes a pretty loud metal clanging noise. It looks like i will pull the tranny tonight and see if thats what it is. Thanks for all the help guys. I will update you when i have news.
