Hey guys,

Got my air con regassed 2 weeks ago after it was drained in Japan. Had it leak tested, etc and it was fine. Now the air con is warm and there's no gas in it. Took it back to the guy who now says the metal line from the firewall to the compressor is stuffed and leaking gas?

Wouldn't this have shown up on the leak test? How does a metal line leak anyway? Is he talking shit and if not does anyone have this line in non leaking order :)

cheers!

normally hard to pick up leaks unless gas and dye has been put in system and then leaked out again, the uv dye showing the leak.

tho the leak should have been picked up if he says he tested it, normally the system is pressurized with nitrogen or lpg etc, and the leak can be heard.

it is very common for the aluminium lines to leak, they are quite thin and can crack and bend easy, especially if they rub against something

usually if u cannot find a replacement line, the leak (usually a small pinhole) is welded up, this will fix it.

cheers dude, yeah it was pressure tested and dye tested... he said it seems its leaking around the valve closest to the firewall.

i'll let you in another thing and that is r32 would have originally been charged with r 12 refrigerant. The ga we use now is a smaller molecular structure than the old r 12 . So this means even if you get the leak fixed it will eventually still leak thru the rubber hoses. answer replace all hoses or keep spending good $ after bad ?

It was recharged with R12. That's what the sticker he put on it says. I'll get it redone if its just seals,

When I did have it I noticed the smell of gas every now and then and condensation appearing on the top of the console near the vents. If that's the case, how would gas get into the vents themselves?

this blows! I was looking forward to air con again :)

Well if he did that it is against the law it is good to replace with SP34E as link will explain,

If he put normal 134A in it dosent mix with the oil in the compressor from R12 or along those lines.

    • Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!
    • Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.
    • Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.
    • Strangely I noticed it either disappear later in the day, or not be present. I definitely noticed when I was crawling around that open wheel thingy entering the pits (that part was audible in car). Driving home and commuting around town for example, I didn't hear it. It's plausible that it was a brake disc or something still slightly in contact. The brakes absolutely felt BAD for the first couple of sessions, huge amounts of shudder and grinding as they got up to temp - And then I actually just forgot about it as the day went on/didn't notice it. The videos were from the morning when this was more present than the afternoon/drive home when it wasn't. I've asked around and got a variety of responses including handbrake shoe contacting hub, CV joints, CB tailshaft bearing as above, and clutch input bearing. I didn't test if it disappeared when clutch was in. I haven't noticed it in any of the other videos nor did I notice it when driving to that extent. More or less hoping the microphone at the rear license plate giving some kind of clue of 'something' but it looks like "spin stuff and see if you can notice it" is the way forward here. I could be smart and use the gopro mic and re-mount it to that location to see if the sound is still present at low speed actually. Sounds like a decent test whenver I have the CBF'ness to drive the car again. Given it's almost 40C for the day of the track day and the next 3 days after, the CBF is high. All I've done since getting home is unpack the car, remove the remnants of the lip and undertray and left it there. I was surprised how well the PMU Club Racers actually worked. The brake performance on the track was absolutely fantastic, best I've ever personally used, no fade whatsoever and the bitiness was almost too good, I was scrubbing more speed off than I needed to, but I also ended up infield when I started trying to scrape off ... less speed.... so...
