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.

      I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.

      Mistakes were made, my R34 Story

      I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛

      Nah, not really responsible for that little fiasco, but I'm still pissed at myself for writing off my 86, or when I reversed my VX into a pole just before selling it, but, meh, 5hit happens to stuff, all it takes is a slight distraction, and life is full of distractions, and "dooh" moments
