I am planning to install this air snorkel purchased on Ebay from the Malaysian seller for $219 + $3 shipping:

Land Rover Discovery 2 TD5 V8 Diesel Petrol Combo Snorkel Kits SLRDC2A 98 04 | eBay

First impression: it looks similar to the Safari snorkel. Shipping was fairly quick even though it came from Malaysia (about 1 week). It came with the template for cutting the holes in the fender, but no installation manual. I will be using the information from this site for the guidance:

The instructions refer to the use of Silkaflex as the sealant for joint between the airbox hose and intake pipe. Silkaflex offers a Automotive version in other countries. But I could only find this version at Home Depot:

Sikaflex 29 fl. oz. Grey Self-Leveling Sealant-106711 - The Home Depot

This version appears to be used mainly for construction work (e.g., filling up expansion joints in driveway, building swimming pools).

I understand the snorkel instructions from various sources in the Web mentioned the need for a sealant is impervious to expansion/contraction when in contact with water. What have you used as a sealant, say something which I can easily get at a local hardware store in the States or Canada? Any tips would be greatly appreciated!

 

I wouldn't worry too much about sealant, you'll have multiple other issues before the water reaches your airbox typically. (spark plugs, ECU, other electronics)

 

i used a Loctite polyurethane product. works fine, for me. it was one of the pl s** products. i always have that junk on hand, don't recall which i used...prolly the pl s10.

 

Thanks Dusty!

I was reading your post too fast at first glance ... and thought I read "piece of ****" from "one of the pl s**"

I re-read one more time and realized what you meant

 

well, a p.o.s. would probably work, for a couple of days...... but only if it was the product of a good diet. i would want to wear some long gloves too

 

Good point about the transmission ECU, axle breather, etc.

I should have added that the snorkel is primarily to keep out the dust as much as possible. I do not expect to do much wading. Much of my off-roading takes places in Central WA or the interior British Columbia region. I have had to change three air filters last summer. I am hoping the air snorkel will help. The kids love the dust, but not the Disco.

The first pic shows the typical "wading" for my type of excursions.... not too extreme.

 

If that's what you're using it for, I fully support it! After the Maine Moose on the loose trip I almost bought one myself. My truck is still completely filled with dust, and the filter was completely gone.

Make sure to keep the snorkel intake facing the rear of the truck!

 

Right on! That is indeed the plan.

I work for a truck manufacturer. We export trucks to Australia. They are addicted to their snorkels. The factory sets the snorkels facing rearward as you can see in the pic. This is to reduce the exposure to white rust (i.e., caked salt from the ocean air during vessel shipment). Invariably, our Aussie mates will revert them to the forward position when the truck land in Oz. You would think it would make more sense to have them facing rearward with all the red dust in the outback. But these trucks do have pre-filters and such which does a significant greater job of filtration and water elimination.

I have been thinking of doing up a pre-filter on the Disco if the snorkel is not up to stuff with reducing dust.

Or perhaps retrofit it with the Manatec mushroom snorkel if water ingress is an issue as we get lots of rain here in the Pacific NW.
