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?

Every now and then I could smell gas coming through the vents and the dash just below the centre vents would get condensation on it. How would the gas get into the vents themselves? How do I fix this, its drving me nuts.

cheers!

my guess it's the tx valve metal lines dont leak unless they are corroded or bent my advice is to go to the guy who gassed it and let him know that there was a leak in the cabin of the car and it all most killed you say you just spent two days in hospital because of it. the gas is very very dangerous maby he will fix it for free ha ha

R134a is not dangerous to u so on't worry about breathing it (I wouldnt do it for fun though). The alloy pipes very rarely leak, unless some dumb arse work hardened it I would take it someware else as there are plenty of other areas to look at. Like the oring used in R12 system may be stuffed and the flexible lines arent designed for R134a.

yeah, think i'll take it to someone with more of an idea... I can't hear the compressor kicking in either I just realised so it may be something along the lines of a post further up the page of a temp sendor for the refrigerant.

I've checked all fuses and stuff, so I think this may be the problem. I'll take it in anyway...

cheers for the help guys, I don't think I inhaled too much gas so hopefully i'm okay :P

Yeah eveything is dangerous, they changed to R134a beacuse it is generally environmentally and humanly safe in reasonable quanities unlike R12 where if u were to inhale it though a lit cigarette it was the same effect as inhaling Mustard gas. I am sure the 500g inside a system would do absolutly nothing.

I guess he assumed all was ok because it was drained at some time. Not leaked.

Mine was fine then over a period of time it began to loose its icy coolness.

Eventually cooling the air so it was only slightly cooler than amb air and thats where it stayed. This happened slowly.

Initial tests showed there was no leak as it was holding pressure and appeared to work well.

This is why I had a 1/4 charge with dye (~$38 from memory) and told to drive around on it so the leak will show up easily.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
