Ok, so I've now got my safari snorkel, looks great, makes a nice rumble and low revs, and I'm sure the air is colder and cleaner. But what about the airbox? I'm not planning on getting the water up to the windscreen, but would like to know that my hard earned $$$ spent on the snorkel is actually going to save my engine if it comes down to the crunch. (pardon the pun!)
The surfs got a round metal airbox (same as hilux etc), it has metal clips that lock it on, however I doubt that it would be very water tight, what have other people done if anything to have that little extra peice of mind? Or am I worrying about nothing...

Put the lid on, then 100mph tape around the lid and air cleaner box, [one lap of tape] then put the clamps on, easy to remove, cheap, and can be done on the road when required.

Jeff

Usually it's a pretty good seal, otherwise dust etc would get in and bypass the filter element. If you're still uncertain ... go with the duct tape.

Rosco, the filter is pushed into the other end of the air box in a round cylinder arrangment so if dust got into the box it would still have to get into throught filter to go into the engine. But if it's pretty good anyhow I won't worry too much about it, always carry duct tape anyway, so if it's a biggy I can double insure myself I spose.

Jeff,
The tape shouldn't be needed unless the clamps don't seem to be holding the lid down tight enough. There should be a rubber "O" ring seal between the lid and the canister. If that's in good nick and the clamps are tight, how can water by-pass it?
JMHO
Cheers,
Roachie

Fair enough Roachie, I must admit I didn't realise there was an "o" ring there, normally I just unclicp grab filter and blow air through it, not paying too much attention, I will have a look and see if there is one and what kind of condition it's in. The clamps are tigher than a ... So shouldn't be a problem. Thanks guys!

Good idea Jeff,
I don't have a vehicle like yours so I'm only assuming that it would simply be sound engineering practice to have a rubber seal....I could be wrong (have been plenty of times in the past...LOL)

There will be a rubber water draining hole in the bottom of the air box too to let any small amounts of water out of the airbox. When going through deep water tape over this so as water does not come back up into the airbox and into the inlet pipe. When you have crossed the water take the tape off again and it will drain water out. My Hilux occasionally gets a bit of water down the snorkle in heavy rain.

Ah, that explains the other question... It's actually raining here today, and I was wondering what happens, I figured it must suck at least some water in the rain, thinking strange as I just spend $$$ to stop water getting in there!! ;-) But yeah, now you mention it my rocky had a drain hole on the bottom at it was the same air box, I'm glad I checked as that would deffinatally need to be sealed up in deep crossings.
Thanks!

No one has ever mentioned other breather pipes that disappear under water, what happens here, particularly if you are stuck in say 500-600mm depth water ????

Just do a search of the forum under "breathers" as in diff, gearbox etc and you will get a heap of solutions for stopping water getting in those places too.

Hi ,

Just bought a new snorkle ( safari ). It has vents in the inlet ( top 90 degree bit ) to let water out . Have checked air filter afer wet weather and it is dry . The safari install manual says to seal the drain hole with sealant .

Glen D, thanks! That would make perfect sense. I actually pulled the air box open last night under tourch light and there is a rubber seal around it, I'll have to look at the drain hole and see if opposite lock sealed it. I did notice he has put some silicone around the air temp sensor which I was glad to see.

Gday Jeff, it's also worth checking that the fitters sealed your snorkel properly, have read a few horror stories about this not being done as well as it could be so you end up with a useless snorkel............Still looks good though...LOL.

Jeff. you'll be amazed at the amount of air a diesel sucks through the filter even at idle!! The best way to give piece of mind is get an assistant to place say an ice-cream bucket lid over the intake (top of snorkel) while the engine is idling while you pass a lit cigarette around any joins in the snorkel or the top of the air cleaner etc. Only be able to do this in short hits otherwise the engine will conk out, but it will allow you to see any leaks because it will suck the smoke in. Obviously do it in your garage where there is no wind. Pays to put a light film of rubber grease (grab a finger full from you tyre shop) around the o-ring seal at the top of the air cleaner and silicon up any other leaks you find. Hope this helps.
Cheers,
Hughesy
