Another Water Issue!

Hi, I have a cefiro, its also a leaky cefiro at the moment. Which living in Queensland you wouldnt expect to be a problem, but it is!

Where the water seems to be coming in is around the passenger side footwell. As thats pretty bloody close to the ECU Im a tad worried. That and every time I get in the car it smells. And the floor is wet etc etc.

It never seems to be a problem when washing the car just when it rains. But its difficult for me to find out if its from driving in the rain, or the car sitting parked in the rain.

So can anyone maybe shead some light on where I should be looking. Even if I can just put something in the hole for the time being to stop water getting in until I can get it fixed properly.

I did find what I thought to be one hole, and I filled that up (just a rag+plastic bag) but its not really working. Due to the position of the leak Im not overly keen to get the hose and go for my life on the chance it really wrecks something.

Think you know what it is post away. Also would I just go to a pannel beaters to get it fixed?

Thanks.

My first car had this problem.. an 85 VK Commodore.

Under the windscreen, kinda under the bonnet, you have a water-drainage thing on either side? It'd be under the wipers, but right on the side, and it's actually a hole in the inner front quarter panel.

If yes, then it's probably the same thing. That water drainage goes down under the car... problem is, it runs over (probably bare) metal, which rusted into a hole somewhere.

It used to fill up the passenger footwell to the point where I had to use a small bucket to bail the water out on winter mornings so I could drive to work.

Nothing else would appear wet... kickpanels off, ECU off, and still nothing wet. I think it was running down the firewall somewhere... but only ever did the footwell carpet get wet.

Frustrating, and looked like more money than the car was worth, so I never fixed it.

The idea I had for fixing this issue was to use a small PVC pipe, shove it down the drainage hole so that it goes from the entrance of the hole, all the way down to under the car where it normally drains out, and just to silicone the top of it. All the water would then get channeled down the pipe, and not touch the metal, and thusly not leak into the car.

If you don't have drainage holes where i've described, then i'm just typing for nothing! =-]

well what i am thinking is the bung for the ECU wiring is leaking

if it is then its an easy fix

jack the car up and place an axle stand under the car

pull the left hand front wheel off

pull the plastic gaurd off

locate the ECU wiring which is up towards the fire wall and look at the bung and make sure it is seated in the fire wall properly

if your not sure then grab a tube of skaflex and cover it up where the wiring goes into the bung and where the bung goes into the fire wall

Daveo I think I have this problem too!!

When I picked up the Ceffy.. I was like WTF! Water on Wolf 3D ECU! Not good lol.. Have had it under cover since so have'nt had to deal with it again.. May be in troubles next time I'm driving in the rain though. Maybe a fault with seals, dunno?

I think AgentR31 is onto something.. the guy that installed the Wolf is apparently dodgy, wouldn't be surprised if there was no gromet. Also my inner plastic guards are gone due to scraping

Sounds like a pain, but to get it properly....dash out :P

I know its a pain, but it may be the only way to see where its coming from / and fix it properly. If its a pin-hole leak, use sikaflex (black body sealer) or get someone handy with a mig to zap it.

It souldnt be too much hassle, if u just do 1 small bit at a time, and lay it all out.

Good luck.

ps - it aint the heater core is it? just when it rains?

cover the ecu for safteys sake for the time being.

Yep done and done.

I pulled the carpet back today, and I was changing wheels over so I had a good look.

It seems there is wear on the plastic tyre guard thing. So water could be getting through there. To me it doesnt look like the ecu gromit, looks ok. I dont have any sealent here so I'll try grab some durring the week and seal it up just to rule that out. But it does seem the water is getting in down where that is...

Im almost thinking it could be something air vent related as well.

Thanks for the help btw, anything else post it up.

Get the hose, and stick it into that water drainage thing I was talking about. Turn the hose on, and then see if there is any water coming in, while the carpet is stuck back.

The area you are talking about in the wheel arch is where the drainage that I was talking about should go.

      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.
