Also would this require me to flush out the entire system? Should I worry about particulate matter throughout the system?
I'll try to get a compressor that is not pre-filled and use the oil you recommend. Do you know if New 10PA15 compressors come pre-filled with mineral oil? or require filling?
Thanks

The valve plate can fail from a variety of reasons. Oil starvation, moisture contamination, non-condensibles (air/water) in the system, excessive oil, old age (normal wear), etc.
If you're already opening the system, take the time to do a flush and replace all the O-rings on everything while you have it apart. You'll flush out the old oil and any contaminants and start with a clean system with a known quantity of oil. The compressor will come charged with PAG46 oil, you can drain it and refill with the oil of your choice.
You will want to replace the filter/dryer as well. Make it the very last part you install before pulling a vacuum and charging.
