Slightly looong winded findings here tonight but hopefully can help/save some underwater adventurers donks out there too
Picked up the truly beautifully manufactured ‘Black Mamba-Airbox’ yesterday
Impeccable welding appears in my slowly failing eyes
My first and only honest concern found was the choice of using the rubber nipple drain thingy much like on my tractor Donaldson that I wouldn’t dare take fully underwater through the creek.
Decided to stop by @Rossco ‘s (The Skinny Mountain GQ Bushman’s :-) shed to gauge his well Legendary experienced deep underwater off-road thoughts for my concerns.
Agreed together that it wasn’t extreme optimal and maybe a manual on/off mechanical simple valve like our other ‘Millweld’ beloved airboxes should be adapted for peace of mind.
Couldn’t help myself later and decided to get a secondary Legendary opinion/advice from the (Vic-Otways Swamp Nutter) @MudRunnerTD.
All three of us are now confirmed on the same page concerned for the OEM design and Daz has kindly put forward a simple solution he’s faithfully used before as I have been known to forget shutting off the manual valve on my other airbox drain.
Here’s a view from the inside as purchased:
Here’s a view bathtub tested tonight:
(slowly filled to bathtub water level in under 60 seconds)
Unfortunately took another approximately 60 seconds to drain out the equalised water level:
OEM rubber drain removed was a complete disaster obviously within seconds:
Now for @MudRunnerTD ‘s Legendary advice:
(test photos below, not finished product:-)
“Find a larger Sikaflex type nozzle in your shed Mark”
“Trim the end off larger for drainage assistance”
“Find an old inner tubey”
The absolute worst I could get it to intake was the volume of the foldable tube before full kink upwards:
The drainage is almost as instant as was tested with the hole completely open:
A brilliant idea thanking you very much DazMaaaaan

Its a Nissan! =====> Its a Keeper!! ....... Got a TD42 in it BONUS!! ....... I'm a lucky bugger! I've got 2 of em!
Check out my Toy --> MudRunnerTD's GQ From the Ground Up
The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

Certainly appears to work Legend
Nearly Midnight and “Fark It” I says !!
$790 for the best of the best hocked my spend for hassle free hoping and a best highway design only found
Why does it take a retard like nuffy me to work out the product has an engine swamping/hydro locking potential?
Honestly dislike bagging products but if you’re gonna put yourself above China spruiking get that simple test R&D shit underway ASAP Legends.

They do work those little valves. If you have a think about it. When the engine is running there is vacuum being pulled inside the airbox. So with vacuum it pulls the rubber valve inwards and seals not allowing any fluid in. This is why it didn't work in your bath tub.

Se below a snip from the Donaldson catalog.
The Vacuator Valve, standard on
the majority of Donaldson air
cleaners, is an important part
of the functionality of the air
cleaner. It is an integral part of
the pre-cleaning stage on two stage
air cleaners.
The dust cup, where pre-cleaned
dust is collected, is normally
under a slight vacuum when
the engine is running. The
normal engine pulsing of the
vacuum causes the Vacuator
Valve to open and close. This
action automatically expels any
collected dust and water. The
Vacuator Valve also unloads
when the engine is stopped.
For the longest filter service life, replace damaged or
missing Vacuator Valves immediately!
If your valve is cracked, torn, remains open, or is missing, dust particles that are
normally expelled can deposit themselves onto the filter and will shorten air filter
service life. Replace it!
The Donaldson Vacuator Valve,
also known as VacValve, is
made in a variety of sizes
and shapes to fit various
applications. The Donaldson
part number is molded into
each part for easy identification.

Thanks Legends, great learnings as always appreciated
Not sure how well the vacuum closing design of the valve is going to work if I accidentally stall the truck half way through a deep river or in the middle of a shocking bog hole though
Wouldn’t that be exactly the same as the bath tub nuffy test?
