http://s1119.photobucket.com/user/Shackeng1/media/ACcompressor004-1.jpg.html (http://s1119.photobucket.com/user/Shackeng1/media/ACcompressor004-1.jpg.html) I have a slight weep of 'green' from my compressor on the 3.2. It is very slow, as the AC has worked OK since it was last gassed about a year ago, but now it is kaput. The green appears to be coming from the top rear of the compressor, any suggestions as to possible causes? :-\ :-\ :-\
PS I'm quite proud of myself, its only taken me an hour to get the pic on the site. :y :y :y
-
if your really lucky it will be from the dowty seal at the rear of the compressor.if its normal it will be from one or both of the body o rings
-
on top of pump at rear the 2 pipes are joined to 1 mounting flange-the seals are under flange-easy to get at when you remove passenger side engine mount :y

Cheers Byron. I'll give up on pics, the instructions have changed on how to do it, and it has taken me 5 years to not understand photobucket. >:( >:( >:(

Is that fairly straightforward to change? :-\

Thanks for that Symes. :y :y :y

well i hope you are the exception that proves the rule,i have replaced 4 or 5 of these and i haven't seen a leaking dowty seal yet.the compressor itself is a monument to modern,cheap,n,nasty sh+t engineering.

if pump is shot-got 1 here mate from one of my 2.5 coffee tables :y

As I have no engine hoist, is there a preferred place to support the engine when the LH mount is removed? And how do I know if it is the pump itself that is shot/leaking? Presumably by a pressure or vacuum test? :-\ :-\ :-\

I went through this last year on my 2.6. In my case it was a leaking compressor. The evidence was around the centre of the compressor. Yours does look similar but you may have to pull it out of its location to completely check the source of the leak. There was no evidence of dye at the dowty seals on mine.
I did manage to replace mine without removing the engine mount but it is extremely tight and when putting it back you have to get the exact angle. It took a lot of attempts but it did go back in. I needed a second pair of hands to secure the compressor when torqueing the unions and I used new seals. Tricky but doable. Mine is all ok now. Oh and the electrical connector on the new compressor was located slightly offset from the original so a but tight underneath too getting the connector back on. If you end up doing the same, make sure the connection cable is clear of the surrounding frame etc.
Also a good idea to ensure the replacement has compressor oil in it before fitting. I hope it is not your compressor, they cost a few quid new, £260 ish I think I paid.

Thanks very much for that Allen. Yes I think the leak may be central, so where is it actually coming from, as I can't see a union at the top centre. It also probably makes sense to fit a new one rather than 2nd hand, given the effort to replace it, not to mention the re-gas charges. :y :y :y

Thanks for that.
Hmmm, I see they say that the Receiver/drier must also be replaced, I assume that is the condenser radiator. Is that necessary?

As I understand it, there is a seal around the whole circumference/centre/main casing of the compressor, part of the original assembly/design. If the seal fails as in mine, the gas and dye leaks. I didn't dismantle my old unit to look in any more detail, just replaced it. As the seal runs the whole circumference, if it fails, where it fails may be at any point around the unit. You may be seeing dye emitted from the top of the compressor or anywhere around it and naturally the oil/dye will run to the bottom where it is most easily visible.
I suppose the main point is, you'll have to remove it to find out exactly where the leak is? As you have evident dye, it is unlikely to be other parts of the system causing the leak but don't rule it out, have a good look around the system before re-gassing. Reason for saying, my Schrader valve (lp port needed tightening up as well).

I used a coolcaraircon.co.uk to re-gas and used their associated a/c parts supply company for the new compressor. I did get an assurance from the local technician that there was no need to replace the receiver/dryer because my system fault was due to compressor leak rather than known seizure etc so guarantee would be honoured. I preferred to deal with people I could talk to during the process even though I was doing the 'donkey work'. You may wish to seek similar assurance? Make sure it is a compressor fault though so far as you can, you don't want to be chasing a/c leaks, that is expensive. At least you have evidence at the compressor.

Looked up the parts company I used..

Just had my system pressure tested(filled with nitrogen) it lost about 3psi over 1 hour, fitter said that is acceptable,will be regased tomorrow,. New pollen filter and both new valves (lp and hp). 8)

i bought a decent secondhand one from robg to put on mine.i think the going rate for a recon one is about £175.i dismantled one to see if i could rebuild it, but basically it was not worth the effort(no spares appear to be available).

Dont know if this is still available
9118305 seal repair kit compressor

Doesn't appear so. :-\

Bit more research and found.
The compressor is also known as a v5, go to google and put in "v5 compressor rebuild" lots of infomation a d a complete rebuild kit is available from the states $28.99 +shipping,so must be available over here. :)

you bar-steward ;D how the ell did you find that information?
i'm gonna have to get one of these kits,i've got several of these compressors lying around
-
I had to replace the compressor on the MV6 a couple of years back, as it would only hold refrig for about 3 months, tell tale sign of dye on the middle of the compressor.
Pinky and I did it twice - the first compressor I stole off on of his breakers when he wasn't looking had the same fault, but the 2nd one has been spot on.

Wil have a look when i get home.

well despite some serious googlin i can find no supplier of these rebuild kits other than the florida geezer who makes it very clear in his ebay ad that he will not ship overseas(not even canada ???)i was going to open an account with a american reshipper and see if that was acceptable,however the seller is not accepting questions or emails either.i'm stuffed,anybody got any mates in the colonies?

Seller seems a tosser. Won`t ship outside the U.S. yet got them listed on Australia & Japan E-bay

Having researched swapping the AC compressor, the following points arise, upon which I would welcome any expert advice.
1. It is recommended that the system requires changing the receiver drier (where is this?) and expansion valve (and this?) and flushing the system before regassing.
2. The compressor must be filled with the correct amount of the correct oil. I find 2 types listed, PAG100 and PAG150, and 250ml listed here http://www.compressortech.co.uk/downloads/Klitech_Wall_chart_04.pdf
:-\ :-\ :-\
-
The AC machine puts the oil in whilst filling with the refrigerant and UV dye.
-
The correct oil is pag150,the omega drier/receiver is mounted on the condenser(large container at side),and dosnt need changing,the oil would be added by the dalek,when its regassed,as for the valve i dont know.

Look at the rad you had from me Chris, drier is the cylindrical gubbins attached to it.
Access to valve is a PITA, Glove box and fan assembly out and you will see it. Securing bolt is a bitch to get to though.

Advise from somebody that has done many an omega a/c - first,buy a new compressor from either trade club, euro car parts or somebody like aircool,any s/h one
will be at least as old as yours...........
When you are at it replace your condensor which if supplied by aircool will come with a new reciever dyer - it will also be the same age as your car and if you get 10yrs you are on borrowed time as they become brittle and leak -£75 from aircool.
Pag 150 is the correct fluid . No need to replace any valves except the high and low pressure fill valve which are less than £6 from Andyc and will also be past there best.

It's a shame you're not closer, I still have the original OE compressor from my car knocking about my garage ..... you could have had it to practice on ;)

thats the guy i found who changed his mind about shipping, seen another place.but be nice for a heads up fromm sasssanch
they also fitted the same compressor to leguna's so might have a chat with reno.

my apologies gemts.this is the ebay geezer I purchased the kits from.300924245806. I wanted 4 kits however 2 was all he had,maybe he can get more? davevgold
