3:30, no answer to my questions yet,...so have not moved forward.

Just to clarify, The compressor I replaced with new DID NOT FAIL, so I did NOT flush the system. THE ONLY REASON I REPLACED THE COMPRESSOR AND CLUTCH WAS BECAUSE THE CLUTCH ON THE COMPRESSOR WAS NO LONGER ABLE TO ENGAGE.....THAT IS ALL!!!!

I measured the oil in the old compressor, about 1/2 oz of clean oil came out, I poured 3/4 oz of proper new oil in to the NEW Compressor to compensate for oil sticking to the drain pan etc and re-installed the compressor, battery tray, battery, and all the other crap attached to the battery tray and brackets.

NOW, the OLD DRIER is removed.....couldnt get any oil out of the drier

Here is my question:

DO I ADD OIL TO THE DRIER EVEN THOUGH THERE WAS NONE IN THE OLD DRIER???

Again, I have not, and I am not planning on flushing the system it was working perfectly until a week ago, and then the clutch would no longer engage,.....so no system contamination, means no system flush required,....so the old oil stayed in the system.

5:30 edit: I went ahead and added 1/2 oz to the drier and bolted her back up,....now vacuuming down.
