i was basing my suggestion on this.. thought iaiaiaiaain was arguing saying he knows (otherwise)best lol

i still reckon theyre maybe a hole in your floor.. all it needs is a crack.. once its moist it will hold water and attract more...

the only other thing you can do is start pulling it apart to find a source...

Thing is, if it was a crack in the floor; it wouldn't stay there afterwards, it'd leak back out.

Great...and if there is, does it make my car unroadworthy?

Can't exactly just seal it right? LOL

If it is a crack; you drill the ends of the crack to stop it propagating any further, then get it welded up. I don't believe that this is the problem.

Remove all the trim you can from the floor area, then start hosing the bejesus out of one individual area at a time; then check for water ingress before hosing the next suspect area. It's the only way.

Didnt Iain and Leon both said the rear washer pipe is under the driver's side?

Yep, we both did :) Maybe it's a case of 'no picture didn't happen' ???

So I pulled off the kick panel & pulled back the carpet & in 30 seconds had this:

That's not to say one of the Nissan guys who put your car together got up on the wrong side of the bed that morning and yours is on the other side. But I doubt it.

Bugger, look how slow I was scaling the pic. Everyone's moved on...

I hope you find the leak.

To check the air con drain pipe, the first question is do you get a puddle of water behind the passenger side front wheel when you park after using the air con. This is the normal thing.

The drain comes down just behind the passenger wheel. see if you can find the drain line and see if water is coming out. You could try puttting a wire back up the pipe to see if you can clear any blockage but I can not see why it would have a blockage. I think a split line is more likely.

In side the car you will need to remove the glove box and then you have access to the aircon unit. I have not seen the drain line but it is in behind the unit so it should be reasonable easy to find. Iain has pulled this part out so he may have some feed back.

only if it is leaking at the lowest point of the floor.

most of the water seems to be held on the floor at the corner of the middle "bump" the D-shaft runs under and the passanger... its like its dripping water from the "bump" and being held at the bottom of the floor.

which is why i suggested a crack. even a stone can chip it if flicks up hard enough..

Yeah ok Aaron; I just think a crack in the floor is an absolute worst case scenario.

I'd be looking elsewhere first. If a stone flicked up; cracks the floor of any car I own; I won't own it for long...

just an example bud. who knows if the gas joint tried jacking the car(for whatever reason) and jacked the wrong point tearing a join seal? I know its unlikely but i wouldnt rule it out. they did manage to drill an extra hole in the fuel filler part as he mentioned..

ok its not a crack. under your carpet is an inch thick piece of styrofoam with sound deadening on one side. unless its punched through that, then gone UP to the carpet, then its awesome water that can run uphill.

im going with andys theory of aircon condenser is leaking or its possible the external vent behind the battery is leaking into the cabin space around the aircon unit. or through it!

youre going to need to remove some panels and see what is damp

I had a similar issue in my R33, turned out that it was the heater core in the passenger side.

Does it have a Smell or greasy feel ( liquid on passenger side )

Check your fluids in your radiator if its running down and requries top up, best way to find out is to turn your heater and let it run for a bit and see if water comes out of passenger side.

Heatercore

Interesting regarding the heater core. Sounds like a real possibility. The fluids is not greasy or overly smelly though...

thats what i told you originally, but the water doesnt smell like coolant.

Have you looked at your roof rack? Sometimes water might come in through there and work its way down the B pillar into the floor?

Just an idea (suggesting something completely different)

I know nowt about M35, but in my R30 I have

wet carpet in drivers carpet. When it rained you could wash your feet in it.The water actually is coming out from above the roof lining near the sun visor.

It then runs down inside the plastic trim attached to the A Pillar.It then drips to the floor inside the door seals.I have roof rails that are fitted with self tappers and have currently siliconed the holes a bit better and am waiting for rain. LOL.

One thing to remember is that water CAN go uphill by capillary attraction.

When I ripped up the carpet to run power and RCA's for amps to the boot, I noticed under the floor where the polystyrene blocks are, passenger front floor was soaked, and drivers side. Both full puddles of water. Soaked it up, haven't checked since will have a look when I pull seats out next time and see what I can find as a culperate.

      You know what, I am enjoying your updates, but I have to say it is pretty poor form to walk into a shop that is paying for space and stock on the floor, try all their seats to work out what you are happy with, then buy somewhere else. If everyone did that the shop will be out of business with no opportunity for anyone to try a seat before buying. 👎

      Yeah mate that’s the plan, I just want something I can have fun in and work on during weekends.  There’s really only 1 road fit to drive the car on and luckily is been redone recently.  I do want to tune it next year sometime, no dynos here so I’m looking at an ECU that can be remote tuned.

      Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA
