I hope I'm wrong, but that sounds like a bad rear mains bearing.
They usually make a bad clank/grind noise when the engine is under load
(like pulling a trailer) but eventually will make that noise even when
taking off.
Get yourself a big flat screwdriver or small pry bar. From under
the engine see how far the harmonic balancer will pry forward from the
engine and go back into the engine. It shouldn't move more than about
1/8" max. If it moves 1/4 like mine did way back when, then it's time
for a shortblock. Do not pry hard.. and pry against the inner ring on
the balancer. If it's going to move it will move easily.

Re: clanking sound that driving me nuts.
Hi Jeff:
I have not put it in Park and Rev the engine, worth a try. I know when
I put it in drive, it would start to make the noise, even when stopped.

Re: clanking sound that driving me nuts.
Hi Jeff:
I have not put it in Park and Rev the engine, worth a try. I know when
I put it in drive, it would start to make the noise, even when stopped.

Re: clanking sound that driving me nuts.
Hi guys:
What's a good book for cars? I know when it gets complicated like this,
take it to the shop, turn around and bend down but I'd like to read and
see how things work. (I work as a network Admin at my corp. inc).

Re: clanking sound that driving me nuts.
If you have a mechanical belt driven fan in that, I would suspect the
clutch on it has gone bad.
'Blew the rad' because it revved too much? That is ummm... BS.
If I can't run my Jeeps at full power (high revs) in low gears off road,
they are broken.
I also would be suspecting maybe they forgot to tighten down the tranny
mount or something, so when it goes in gear, it could be shifting over
or they left a bolt loose in the torque converter or the clank it the
bad fan clutch.
