Outer Limits 4x4 Board

just installed the snorkel on the GU and was wondering about the 2 factory drain holes.
now do i plug them up and have it so air can ONLY get in via the snorkel, or do i leave them so a little water can still escape out?
one is a really small hole maybe 2-3mm diameter and its at the bottom of one of the air box pipes. and it looks like its desined to trap any water that does enter. also is the little rubber valve looking thing attached to the bottom of the air box.
my understanding is that when water is in the box it drains out through the valve but when the engine is reving it closes from the suction of the engine..
any thoughts?

i tried blocking the top of the snorkel with my hand to see if i could stall the engine to see for leaks and these two points are the only place i found.


also what do people do when getting their car washed?
i usually do it myself but im thinking that one day if i ever do go to a automatic car wash... if they make them 2.1m high?? that what should i do about the snorkel? is it designed with it angled down to not let water in?

any thoughts people??

block them up ,in a deep water crossing those 2 small holes may stop u short of getting across

a good silicone should do the job ,also make sure its oxygen sensor safe or you may cause yourself a problem

where does the water go when its PISSING down rain and your driving in it for a few hours?
Dont block the drain holes... Why do you think they put them in there?

... and be organised so you have some tape or some other way of blocking them when you stop and check under the bonnet to prepare your vehicle for a water crossing.

this is what ive been thinking.
i need them for everyday driving but on a long deep crossing i could get in shyte.

maybe if i block the one thats hard to get to, and leave the other one on the airbox.
i might look for a plug that i could use when doing big crossings.

I have never bothered to block any holes while crossing bonnet deep rivers.
others in our club wiht safari snorkels on GQs have also done the same on same river on same trip with no issue.

if your in doubt, call Safari and see what they have to say.

Call me stupid, but I'd be mighty surprised to hear of a snorkel manufacturer who wouldn't factor in deep water crossings...so odds are the factory holes are there for a reason.

fitted a safari snorkle not long ago on a gq and the destructions
said to silicone the rubber flapper up.
i was told any rain sucked in would dry up with engine heat. cheers

Put a donaldson head on it and it won't get water in it from the rain

I am going to Weld up the std hole and put a Boat bung in, That way im guarenteed a perfect seal when i need to cross deep water. Seems the easiest/cheapest/foolproof method for me

Cheers

I'm not going to call you stupid, but some of the manufacturers apparently claim the snorkels are for "dust". They don't make a big noise about it, but they hide behind it later when people total their engines while relying on the snorkel to keep them safe.

I Replaced the rubber water separetor by Bronze welding a 12mm thread where the OE rubber was.

Than ran A flexy hose down in the wheel well with a ball valve where its easy to operate open` closed

Not all cars have silly rubber valve and they dont hydraulic the engine when it rains.

Also what if the silly rubber valve is submerged for a while whilst the engine is not running (maybe the engine stalls and you have to be recovered?)

Do you trust a 15 year old bit or crappy rubber to protect your engine?

Seal the bastards up

Surely that can't be Safari - they use a video of a 4x4 in bloody deep water surviving because of their snorkel.

Fascination with deep water ?? Just stay away Honestly do you need to be driving through bonnet deep water ? I would be thinking a few things through first -not hacking on anyone but if it can be avoided then do soo. If you ultimately have to then I would be tarping, sealing holes with tape/silicon everything at your disposal...

As for holes in your airbox, It is like weep holes in the mortar of top ridges when installing roof tiles. Water and shit can get trapped and if it doesn't have any where to go then the roof will leak. THey are fairly necesaary...

In victorias high country river crossing preparation can be pretty important if you want to have a stress free trip. rivers can rise overnight. sometimes there may be another way out but if you are equipped properly to deal with a rivercrossing then it can be the difference between something that could have been stressful and altered your plans in a big way, or somthing that simply isnt an issue. (but kind of fun all the same) another problem can be misjuging the hight of the water, or if you get stuck half way accross, a snorkel that works properly is good insurance.

Nup, cheap insurance.

I know of 3 people who swamped their engines, and it wasn't doing anything to 'hard'...all it takes is a bit of bad luck. I'd much rather spend $500 now than $4000K+ down the track.
