Tahoe rear txv replacment after compressor grenade

Year: 03
Make: Chevy
Model: Tahoe
Engine Size: 5.3
Country of Origin: United States

My Tahoe compressor grenaded! Real bad, left lots of metal, removed rear txv for replacement noted oem part has screeen instaled with lots of metal in it. Replacement 4 seasons unit does not come with a screen?
Am I suppose to find a new screen or reuse / clean current one?

I am also in the process of full flushing of the system removing all oil. When I refill pag46 into system am I suppose to split the oil front and rear or is it ok to dump all the new oil in the front and let it work its way through?

All a/c systems at assembly plants start with full oil charge in the compressor--so what do you think you should do?-- I'd put an inline filter in 3/8 line in front of TXV- somewhere underneath the truck-- they are sold on this site..

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Whats your opinion of putting the inline filter before the condensor (which is brand new)? I have enough room to put it before the condensor, after the condensor but before the split for the o tube and txv or before the txv.
