Perhaps I needs a little air intake sealing
Might need to fill the airbox to find the culprit

Pretty glad mate called me to kill her due to seeing exhaust steam.
Water right thru induction system.
We seem to have gotten away with it (once dried have driven 100km with no faults etc)
but bloody close to carnage

I'm not familiar with the 2.4. Are we looking inside the airbox without lid on? And no snorkel? Cheers

Vid is of scary side of intercooler
Disconnected hose at intake manifold
Airbox was apart and drying
Air filter wet but not destroyed amazingly
MAP and MAF both got cleaned with contact cleaner
Took a few minutes to clear intercooler of all water
Reckon at least 100mL got past the airbox and to intake
Snorkel insitu but clearly not 100% watertight

**** Steve!
That's scary, I think you've just won a minor lotto prize, that's a little too close for comfort.
Having recently had the fear I'd hydrauliced the TD5 in the Disco I think I know how you felt.
At least the chambers will be nice and clean now, they've been steam cleaned ! :D

Yeah I can tell you that the goldy went down very well
After I had cleared the water cleaned the sensors
And she was purring nicely
Nugget kit is a definite option

1. Hows the turbo?
2. I have had water inside my TDCi (2.2) airbox before, complete with splash sodden filter element. Water, at least in liquid form, didnt get past there though.

I assume the turbine impeller and Vanes have been steam cleaned?
My hope is water going thru the induction system was misted not a glut full
Air cleaner was visibly unharmed in processing so I'm guessing it filtered the water into a mist
Video would be showing the water that collected in bottom half of intercooler being burped out
System bone dry after 100km up to seisia
Hoping for the best
Thinking silastic sealing ducting and dump valve will do as good a job asnugget kit and means access to IC hoses and alternator not hampered by 90mm hose

If any of the components are made of high density polyethylene, (HDPE) then silicon products won't stick to it, and in fact almost nothing will. The best you can achieve is to form a gasket using a polyurethane sealant between two surfaces which are mechanically held together.

No doubt if you have a snorkel fitted for deep water work (as opposed to just raised intake to avoid dust etc) then full sealing at every joint to the airbox, airbox lid, and every joint to the intake manifold is needed. (Sealed to the point where blocking the top of the snorkel will stall the engine - I suppose)
The following advice would only apply when there is no snorkel in play and pushing the documented fording limits a bit to the point that a good solid splash may hit the standard air intake on the side of the fender:
- In this case (my opinion only) its better if the several joints in the stock intake ducting are left unsealed, specially all the water drain valves.
- Then the unsealed ducting acts like a drinking straw thats got a bunch of perforations in it (i.e. fails miserably at delivering liquid when you suck on it!).
- throw a bucket of water hard at the intake duct opening, with the engine running, and I bet the water wont get sucked into the airbox at all (the several other gaps in the ducting will suck air no problem when the proper opening is dunked.
- prove it to yourself with just a piece of A4 copier paper. Run the engine. Put the A4 flat across the air intake on the fender. There is barely enough "suck" there to hold the A4 from falling to the ground. Get someone to increase engine rpm. A bit more "suck" but hardly - neither the paper nor engine seem to be fussed at all.
Compare this to what will happen where you seal or replace the stock intake ducting so well that covering the stock air intake can stall the engine - if that setup then gets a bucket of water tossed at the open intake end, that water will be gulped in with a lot of force!.

I had a similar heart starter last year crossing Scrubby Creek on the Tele Track. Water was 1.4m deep and it's at least 50m across. My 2010 110 has stock suspension and a safari snorkel (which as tact says is really just a raised air intake and yes, every time I open drivers door the mirror gets knocked back by the snorkel) and I use a wading apron. Sally lost power 3/4 of the way across and chugged up the short steep climb out belching steam. I let her idle while we let the water drain out the doors, she ran rough for a few minutes but then just purred away as we set off again! I didn't even pull the cover off the airbox.
I also had a bit of trouble with water on the electrical plugs up on top of the engine/alternator so taped these up for and no probs for the rest of the run to Cape York. https://www.aulro.com/afvb/images/imported/2017/05/231.jpghttps://www.aulro.com/afvb/images/imported/2017/05/232.jpg123736

How did the camper cope with water that deep?

I'm back home now no further dramas so hopefully all okay
I too had a wading tarp on but thinking the water likely coming in through the guard
Seeing how much water mine spat out I'm glad I took the time to remove ducting and. Lean ZmAF & MAP
I reckon you must have been even closer still to a hydraulic event
I would suggest if you see steam shutying the engine down should be priority one
Scrubby was a muddy sloppy mess this year I'm glad my 130 drank the crystal clear nolans over scrubby!
The deepest crossing was actually a seasonal swamp before nolans
Although deeper I was able to build a bow wave and carry on
Nolans was a steep drop into windscreen deep hole, even with the blind the sudden dive obviously flooded the engine bay
Was a good early season run and the PDR is a super highway
Won't be long before it's black all the way!

This was what led to the Donaldson precleaner on SWMBO's Wrangler. We were crossing the Macquarie river at about 30cm depth when a splash from the tyre dropping off a large rock hit the snorkel intake. The result was at least a cup of water in the airbox which had to be mopped out with a towel due to the duckbill being removed when the snorkel was fitted.

We dragged a 2015 Jayco swan around the country, so no camper in tow up the Tele thankfully!! I left the trailer in Weipa for the Cape run, we had enough kit on the roof to swag/camp, food and supplies & a fridge in the 110. I didn't want a Jayco fail to stop my fun; although I was quite surprised how well it stood up to the 42000km journey.
My wife wouldn't have done the trip with a proper camper nor would she tent it with 3 kids - it was a big compromise but one that made it possible. https://www.aulro.com/afvb/images/imported/2017/05/204.jpghttps://www.aulro.com/afvb/images/imported/2017/05/205.jpghttps://www.aulro.com/afvb/images/imported/2017/05/206.jpg

Neil, the Safari Snorkel has drains around the neck to allow water that passes through the intake to drain away before going down the tube. These holes would prevent low pressure in the intake tube should the the mouth be blocked or hit wit a large volume of water, I would have thought.

We have a Swift (wouldn't get the wife away without it) and I have zero complaints. Have taken it some pretty hairy places and it's held up great! Never any dust inside, nothing has shaken loose, the only thing I'm not sure about is a deep water crossing with the door and fridge vents.

Yeah I usually would have shut it down and started pulling it apart straight away but thankfully it all turned out fine. It had rained the night before & falls were heavy in isolated pockets - Scrubby was holding a lot of water but not v muddy. Nolans wasn't as consistently deep, except for the drop but it sure was nice & clear. I was concerned about crocs at both Scrubby & Logans but not half as much as my mrs & kids were - so if I'd walked it they would have been hysterical.
The PDR was not bad in places but absolutely atrocious in others - the truckies were cursing it in November last

Yeah the Jayco held up quite well but definitely don't take them through water deeper than the floor. They are not at all watertight.
I lost a wheel off mine at 100kms an hr near Gregory. Sheared all the studs off and the wheel went bouncing off into the scrub. Found it just before dark but it took 2 1/2 hrs. The road from Lawn Hill was a bit nasty in places

Scrubby has an easy go round now just upstream - tyres hardly get wet as opposed to that 50m long muddy 1.5m deep cesspit!
Logan's looks a little gatorish but to be honest none of the OTL crossings except the Jardine would hold a saltie for very long. Maybe you could be unlucky with a passing through small male??? all but perhaps cockatoo lack sufficient food supply to keep a salty satisfied for long.

That would be a good design feature, Billy. Don't know how hard a bloke would have to be pushing limits to get the opening of a snorkel at roof height well bucketed with water! ;)
Definitely more of a risk with just the stock air intake. (Where my preaching for leaving joints unsealed were aimed)
