The other day I was driving in moderately heavy rain and when I stopped though I would
check to see if any water got in through the
snorkel. Had a look and found a bit (maybe 1/4 of a cup) of water in the bottom of the air filter housing !
The
snorkel is completely standard and I have never had any problems - just wanted to ask if anyone else had experienced this !

Not sure about your model troopy but when I worked for Toyota 88/92 (pre delivery manager not mechanic) the troopys had the factory snorkels but were in a box inside the vehicle and was part of the pre delivery section to fit them up. The holes etc were already predrilled so just had to push together couple of self tapping screws through the
snorkel to hold together all done, there were bits of foam that was already stuck to the
snorkel joints. Sit the cap on top with a clamp that was it. NO silicone what so ever was applied to any of the joints. I always wondered even back then how we didnt have them come back in with blown motors due to water been sucked in through the joins. Maybe there were more
farm vehicles and never were really dunked in the deep ?? Regards Steve M

Steve,
The factory snorkels were never designed for water. Toyota have always called them "dust snorkels". If you want to use it for water, you need to take them apart and seal them up.

Makes me wonder if the customers were ever told that or I suppose it was up to the customer to ask the question. There you go learn some thing new every day. Worked for them for 4 years and didnt even know the correct name, always thought they were your everyday
snorkel and Toyota just been tight and not wanting to supply some sealant/silicone. Regards Steve M

The vehicles had a fording depth of 700mm. Thats
well below the
snorkel, so the people in the design office figured there was no need to seal it or make it one piece!
Water can usually get in thru the rubber flaps in the base of the air cleaner box, so if you want to be seriously waterproof, you have to seal that up too, but its nice to have somewhere for the water to get out!
They have always called it a dust
snorkel - problem is the average customer assumes they are for water because of the advertising by Safari and Airtech with their one piece aftermarket snorkels.

They were prone to splitting as
well.I was bent down doing my shoe up and glanced up at our 75 work ute and noticed in the peice that runs along the front gaurd a split on the underside about 10cm long. Soooooo easy to miss

Thanks for the
feedback - I have noticed the rubber flap at the bottom of the air cleaner box which would let water out - question is then with a fully sealed
snorkel how would any water get out if it got drawn in when driving through heavy rain ?
It's good to know that the standard
snorkel is not suitable for water crossing greater than around 700mm - will need to seal it up or get a after market one to be sure for water crossings !

Troopy,
If you have a good look at the
snorkel and air filter housing you will see that as the air is drawn down the
snorkel and enters the air box at a angle.
This allows the air to swirl around the air filter housing forcing all the heavy particle's to the out side of the housing. This is one of the reasons that the housing is round.
After the heavy particle's, dust, bugs, grass seeds and rain, have swirled around they will drop to the bottom of the housing and will fall into a sump located on the bottom of the air filter housing.
On the bottom of the sump is a rubber flap with will allow water to drain out. This sump should be removed and cleaned when the air filter is cleaned.
If you had water in the bottom of the air filter housing, remove the sump, it might be full or blocked.
Wayne
