Talk to me about snorkels

[Ogeechee 4x4]

Wanted to pick y'all brains about installing a snorkel.

Anyone seen/bookmarked any that they particularly liked? :popc1:

You do have a point, Gubni. If I'm ever in the position to need a snorkel, I'm going to need more help than than an extended air box.


I've wanted to copy a buddy's down in Florida for a while, but i'm not 100% sold on the idea of running an open element filter in the rain... cratchhe:

I dono, I think under hard rain water may get sucked in. Most snorkels have a cover to help with that.
It should also dip lower than the carb so it can pool.
Here is the thing, its only as good as weakest link. Even if you keep the engin running, water still can get into tranny,or diff vents, electronics(especialy the dist). All of these things need to be vented. In baja we ran the intake filter between the seats, and plumed all other vents (diff, tranny, t-case) too the main filter. The distributer cap can be rtv'd down, but you still should run a vent hose for it.
On my eb I have a hood scoop(z28 cut to fit), the hood is cut above the carb. I made a base plate for the aircleaner that seals around the hood. All the air comes in from the back of the windshield. I also ran my other vents up to that base. For the distributer I put dielctric grease on the base of the cap and a distributer boot over it. It can breath as it needs, but water has a hard time gettting in.
My rule of thumb is if water goes up the hood more than half way I need to shut it down or be almost out.
Something else to think about is the fan. If you have a mechanical fan it will work like a propeller and suck the rad into the fan(completly deforming it).
A good radiator guard will help prevent that, and a good shroud will help keep the spray at a minimum. If you have electric fans be sure to have a kill switch.
Just my 2c.:rebel:

That's what i had in the back of my mind too....Or perhaps when it's just sitting in the yard or in the campground under a hard rain and i need to fire it up before the filter has a chance to dry.

Very true. I'm not trying to make a submarine out of the vehicle, just trying to minimize the chance of sucking water through the air intake during those all-too-common "it didn't look that deep!" mud holes...


And I'm just kicking around the idea at this point. It's not a mod that I'm going to do right away. It's hard for me to drill that 3" hole in my fender...

ABS is usually the material of choice for these items. A snorkel is great but it needs to complement a large assortment of other modifications before using it. Think about your EEC. If you have to use the snorkel, you are already dead in the water and I can guarantee you are not starting back up on the other side of the hole.

Maybe I should re-think this idea. There seems to be a unifying theme in y'alls responces. cratchhe:

I was thinking of going low-tech with 3" PVC and a 3" in/out y-pipe to connect it to the air intake tubes.

Yes, i know the EEC is low in the kickpannel. Yes i know it's a major PITA to lengthen those wires one by one so that I can re-locate it higher.


I'm really not planning on doing this, but I finally found a picture of my buddy Jimmy using his snorkle during a Richloam ride...the engine stalled, but cranked right back up once he was back on land. E4OD #3 was a different story, tho... :crying:
