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.
Don.
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)Quote:

- 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/im...017/05/231.jpghttps://www.aulro.com/afvb/images/im...017/05/232.jpgAttachment 123736
How did the camper cope with water that deep?Quote:

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.Quote:

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.Quote:

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.Quote:

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.Quote:
