Air Con Pipe Not Available

[harrylime]

I finally found the pinhole leak in my aircon system. A leak in the lower pipe from the cylindrical device in front of the condenser, to the compressor. First problem, I can't see how it attaches to the cylindrical device (the one with the sight glass) as it just looks like a grommet at the end of the pipe.

Second problem, Lexus want over £140 for a bit of pipe. Third problem, which removes the second problem, is that the part is no longer available.

So I'm a bit stuck. Perhaps an aircon specialist could fabricate a bit of pipe, to replace or repair the existing. I may be able to get the part from the USA, although they are still costly.

I may first attempt a repair with epoxy metal. I recall repairing a cracked Mondeo engine block with this stuff and it was amazing. Has anyone tried this and if so, can they recommend a product?

I dislike "bodge " repairs but as parts availability becomes a problem, it may be necessary to be a bit more creative

Of all the Ls400s I have owned (quite a few) I have never encountered a leaking a/c system.

There are a few guys on eBay breaking one so it might be an idea to message a few for the part you need.

where the leak is, the pipe was touching the wiring harness. I assume it, rubbed over the years or perhaps collected water, which has corroded it

Did you get the part number for the pipe from Lexus? If so you could try Amayama for the part or an AC specialist as you mention may be able to make one up for you.

thanks chaps, I have the part number. I've tried the epoxy repair today, the putty did not seem to want to stick to the pipe, so I tried with less putty and put two applications on. I'll know when I get it recharges(or perhapsa week or two after), it's 50/50 I think
