I thought i was theor

This is a 1989 chevy k1500 5.7l with 198k on it i dont know were this noise is coming from their is metal shavings in the oil http://cloud.tapatalk.com/s/57c85f1086a0f/20160901_124036.mp4

This all started when i toped off my transmission fluid

So, you have a chirp/squeal that started suddenly.  Do you see evidence of metal in the engine oil or transmission fluid?  Automatic or standard transmission?  Did you remove the flywheel/converter dust cover?  Can you determine approximately from where the noise is emanating?

[Joshua_Remillard]

It is an automatic and Yes their is evidence of metal in the oil its on the dip stick i have not drained the oil to see the severity of it theirs none in the transmission fuild I did remove the flywheel when I replace the motor

Make sure the converter dust cover is properly installed and not dragging against the front of the flexplate.  It is an easy error to make.  Simply remove the dust cover to see whether the noise goes away.  If it does, pay particular attention when sliding the cover back into place around the crank flange.

How does the motor run?  Any misfires or backfiring through the throttle body when rapidly full-throttling the engine?

It misfired for a long time and stalled under load I fix the timing and the problem was fixed but now it seems the have a bigger problem

What's the engine oil pressure, cold and hot?  Have you noticed any changes in oil pressure?  You may need to verify pressure with a manual gauge.  To keep the problem from escalating, be careful that the engine isn't starving for oil due to a failed pump or plugged filter.

I assume you found "pearly" oil on the dipstick?  The most routine cause of metal in the oil on a SBC is a wiping cam lobe - not to imply that other causes aren't possible.  A suitable approach is to diagnose the source of the squeal/chirp and determine whether it is in fact related to the metal in oil.  A 24" - 36" long 1" heater hose used as a listening tube can help isolate and pinpoint the source of difficult noises.  Remove the flexplate cover as previously suggested.  While the cover is off, check crankshaft endplay - it should measure 0.002" - 0.006".  You may need to remove the valve covers and visually inspect rocker arm motion to verify whether it is consistent between cylinders and that the rockers are receiving adequate lubrication.  Don't remove the oil pan prematurely.  Check what you can before tearing it down and immobilizing the engine.

It seems to me the priorities facing you initially are verifying oil pressure, diagnosing the noise, determining whether the noise and metal in oil are related, and then narrowing the cause(s).  During diagnosis, don't run the engine any more than necessary to attain useful answers.

Could it be the oil pump

You thought you were theor? 89 K1500 isn't this style truck. Are you sure this is what you are working on?

Sure looks like a 1989 T400 K1500 series chassis in the video not an RV series squarebody.

I'll try to help anyway. 

With possible metal flakes showing on the dipstick and the slight low pitched knock that's barely audible in the video over whatever is rubbing I would be worrying about spun main bearings...  If it's really metal flakes in the oil. 

Did you explode the torque converter internally?  I've seen converters balloon and put excess pressure on the crank nose.  It wiped out the thrust bearing surfaces of the middle main bearings on a 1990 Ford F150 302 Windsor and a 1989 GMC T400 K2500 with a 350 on my employers' plow trucks.  They both took Engine, Torque Converter, and Transmission transplants to fix.  Hopefully that's not the problem.

What does the oil look like in the drain pan and the filter? 
Can you post a picture or two to show everyone the metal flakes in the oil on the dipstick and in the drain pan would be good.  It might not be metal flakes...  Then again it might.

Check the tensioner pulley, AC clutch, and the water pump pulley.  They will squeal like stuck pigs.

Metal in the oil, squeal, and knock are all good signs of a spun bearing. I would jerk the valve covers off, run it, and if all the rockers are moving about the same amount I'd yank the engine and start pulling caps.
