I just opened the system and found the orifice tube full of metal and black gum. The funny thing is I can not get a new one or the old one back in all the way. How do I go about getting it reamed out so that it will be able to go in all the way. I know I will be doing a new compressor...etc. I am just curious about this problem. thanks
This problem has occurred on a couple of vehicles. First be very careful if you decide to 'ream' the line to fit. Excessive metal removal or an irregular seating area may contribute to liquid refrigerant blow by.
Insure that the line is clean inside. Often this debris field will build up in the line and may prevent proper seating of the valve.
Also insure that the oring is lubricated....we simply cover the orifice with mineral lube and stick it in. Can use PAGs....we simply use mineral lube for this and all other orings.
Good luck.

Yes, be careful about reaming. You might be better off buying a new line. As stated, lube the O tube well, and it will go back in, I would suggest changing the condenser on that one if that much junk was on the O tube..Hope this helps..

Those are great suggestions. I have tried scraping it with a small screw driver but dont bring up anything substantial. What type of aggressive cleaner do you suggests. thanks
I was thinking of something aggressive like Brake Kleen and a small brush like engine builders use in small oil passageways. Be aware that whatever you do it will all be going into the evap and will need to be cleaned out of there before reassembling.
