Gentlemen: would you trust a 16 year old nippondenso compressor or would you replace it because of the age of the compressor? Also does converting from R12 to r134a cause all the old contaminants to contaminant the system.
Oil and drier of an R12 system is not compatible with R134a in my opinion. If the compressor is working fine I see no reason to change it. If it has been sitting around with no refrigerant I would suggest replacing it as the seals most likely will have hardened and leak.
If it pumps strong and does it quietly, why not keep it. I agree with Tim though on replacing the seal.
There shouldn't be any contamination if the compressor didn't self destruct. But it is a good idea to thoroughly flush the system and replace the receiver dryer. If you switch to R-134a, as Tim noted, you will need to change oils... especially on such a small system like the Honda where there is little room for the old oil to migrate to.
