Re: [MBZ] AC Leak
Replaced a bunch of O-rings yesterday, everything I could get to without a major undertaking. Still leaked down to around 20"-25” Hg after 30-45 minutes. I replaced the receiver dryer, charged the system with R134a and used the Cliplight sealer that saved the 500 evaporator. 24 hours later it’s still making ice cubes. I’ll continue to watch it to see if it leaks down, but previously it would be dead by now so I guess I had a leak somewhere and the compressor shaft seal is intact. I went back and looked in my purchase inspection notes and saw that the PO said it would leak down every season, not completely but enough that it would need a can of refrigerant to make it cold again, so maybe it’s the leak that he was experiencing and it just got worse… Dan ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] AC Leak
You can find complete sets for a specific application for around $15.00 or less. You can also buy the individual O rings, but I figure it can’t hurt to have the whole set. About the only thing you might not need is the big seal/O ring for the manifold on the compressor if one is used.

Re: [MBZ] AC Leak
I would add that this is a native R-134a system, not a conversion. Also, low side pressures did come up to the 30s when I added refrigerant, but dropped when I closed the service valve to the can.

Re: [MBZ] AC Leak
Here's what it was doing this morning, with an ambient in the low 80s: Low side was at or near zero, high side was around 150. I put about half a can in the system and got bubbles, but it was cooling slightly. Low side barely came up, but high side remained at 150. I left it at that, as I'm probably going to take it to someone to troubleshoot. Interesting enough, I did notice that the low side service valve was bubbling when I was putting the cap back on. Based on this I don't think I have anything catastrophic going on - it didn't leak down completely over a week's time, so I'm suspecting a leaky valve or a bad O-ring maybe. Not sure how to interpret the pressures I was seeing, though. Thanks to all who commented. Any other observations are welcome.

Re: [MBZ] AC Leak
Always suspect the high side service valve. For some reason the "standard" quick-connect valves are anything but on the high side, and I've resorted to getting adjustable depth connectors on my hose set. It's very very easy to damage the Schroeder valve in the high side fitting if the hose set plunger is too long, and every conversion fitting I've seen (along with factory ones) is a different operating depth. I've wrecked a few myself. That said, you need to check all the high side (read hot) o-rings and lines, the one between the condenser and receiver/dryer is prone to failure, there are four 0-rings on the receiver/drying and the ones on the expansion valve tend to fail as well. UV dye is a great tool.

Re: [MBZ] AC Leak
Drop some UV dye in it, or an oil recharge with some in it. If it's the evaporator, you'll (eventually) see it around the condensate drains. Regardless, you'll have a good idea of where to look. I wouldn't be surprised to find a leaky service valve, especially the high side one. -j. -- John W Reames jream...@verizon.net Home: +14106646986 Mobile: +14437915905 > On Sep 20, 2014, at 20:55, Dan Penoff via Mercedes > wrote: > > I gotta find out where it's leaking first.

Yea but once you get that stuff in there it's a pain to get out. Most ac people won't hook their machines up to it either for fear of contamination.
