When you get around to replacing it, fit an O/S recirc assy which will place the motor on the inside. This means it's easy to access by removing the glovebox instead of half the dash.
I swapped both of mine around while I had the dash & frame out but found the O/S is still a PITA due to the frame now blocking it.

I finally got around to contacting my mobile air con guy and he is going to drop but tomorrow and have a look.

He suspects a slow gas leak from either the compressor seal, TX Valve or evaporator. So he is going to top it up and we will see if we can nail down the leak

Hi

Well she is still full of gas and the way it is behaving it seems it's the TX valve playing up. Luckily it can be replaced from under the bonnet, so no dash out :p

I asked him about Hychill and he said it's a better gas but because it has smaller molecules it's harder to keep in the system. He said he started using it on P38's and found he had to come back and refill them with r134a after a few months.

Given that I have new hoses I think i will give the hychill a whirl when I replace the TX valve.

I am wondering if I should also replace the Tri-state and low pressure switches while it has no gas in it. Not sure about the long term reliability of those switches

I've always heard it's the other way around. Hychill leaks a lot less ... due to the lower pressures it runs and bigger molecule size. Someone else will look it up for me :p :wasntme:

From what I can see hychill has bigger molecules so as you say it should leak less.

Perhaps the old hoses just aren't up to the job anyway, mine were leaking very badly before I replaced them

Hello all - I too have a similar problem but pretty sure I have no faults showing. Can anyone recommend a good outfit in Melbourne who knows these cars?

Thanks
