Ok, so ive been trying to figure out a way to put a snorkel on my truck that is cheap, effective..... and dosnt look completely hillbilly delux.

Im not against PVC tubing, but its gotta be done right.

First things first, i do not like the look of the snorkel that comes out of the fender and follows the body line up the hood, and A pillar, to the roof. it just dosnt look right to me.

I looked at doing what another CK5'er did on his truck and route the snorkel into the cab, where there should be plenty of air durring the crossing. but My truck is already a loud SOB, so i dunno if i want the vacuum/whistling/sucking sound inside the cab with me. I do hope to put a turbo on this thing at some point, which will probably make it worse.

but in researching i stumbled across a (im ashamed to say it) jeep design that is pretty awesome. He routed the PVC out of the fender up by the A pillar. and connected a 90* bend with a threaded section. This makes a snorkel that looks way to short to be useful. he then carries a 3' section of threaded PVC in the truck, and when he goes offroading and meets a stream crossing, he pulls out the length of PVC, and screws is into the snorkel assembly, putting the 90* bend over the roof of the truck.

Like i said, i dont want to cut a hole in the fender. But i was thinking, i could do the same thing, but come up through the cowl. when im driving on the street, i could screw in a plug that was more or less flush with the cowl assembly. When i go offroading, i can undo the plug, and screw in a 3' extension pipe to make a snorkel that reaches over the roofline of the blazer.

Thoughts?
 
I have thought about coming up thru cowl. Hood wouldnt open with the snorkel on however. To look less ghetto and ,in reality, a pipe large enough to not choke the motor I think it would need to be oblong. I would use dzus fasteners to hold it down If I do this some day I was going to have a cap to install for everyday that wouldnt suck water from the windshield

Maybe way, way in the future
 
...I've been working on a mental picture of some how marrying a H2 type rig, or something off a tractor....

This is why i bounce ideas off the bretheren here before i do anything, i didnt even THINK of that. :doah:
 
If its easily removable, there are very few practical times that I can imagine that the snorkel would be vital and need/ be able to do anything to the engine or battery. The outside(recirculate??) ar inlet valve to the heater is also where I would come up so that would also need to addressedd.
 
I was thinking of making a snorkel as well. I have some pics of snorkel set-ups coming through the hood. I can't post until I get back to my work computer. One neat idea I saw about coming through the hood was the use of a heater hose which was a flexible hose. There was a bracket on the hood and the hose was held on by hose clamps. Because it was flexible it would allow the hood to lift a little where the clamp could be removed before raising the hood the rest of the way up. It was also easy to remove and since it is flexible it can be rolled up and placed in the tool box.

Now I am thinking that I will not be driving in water that deep, I'll just use my boat.
 
If it comes out of the hood, the ducting has to be flexible or you can't open the hood (the reason most people use the fender). If your snorkel will be "temporary" then you can really exit almost anywhere and just make a plug for the hole.
 
another option people do around here...is they remove their heater fan.... then go from carb into the cab right there...


I wanted a snorkel and didnt want hillbillyish look.. ok ok.. wife wanted it to look right.. so here she goes..


$321 total cost...

If you wanted to get REALLY clever, what you should do is run an intake tube down your firewall, under the cab, and then back up the rear of the cab to the roof. Then cap it with something to keep birds and kids out. :) Now you have a little scoop behind the cab which is not very visible, full snorkel, and fully functional.

Edit - is this for a Blazer or a pickup? I was thinking pickup... If you had a Blazer, you could sort of do something like that but cut through the floor and then run up and cut another hole through the roof. Yeah, that's the ticket! :D

The issue with that, is that if you actually need the snorkel, A LOT of tubing is submerged under water, at least a few feet. Even in teh event you don't need the snorkel, the intake tubing is still under water. This sounds like it would be asking for leaks, which would not be good. And the farther under water, the more water pressure will be trying to force itself in. In the snokels from the throttle body, they probably only end up less than a foot under water. In your situation, same water depth, the tube would be more than 4' under water. And keeping the air cool in a tube that won't melt under there would be difficult.
 
The only other idea I had would be to run through the firewall and up the pillar near the windshield and out the top. Do it on the passenger side perhaps?

Either that, or stay away from those killer parking lot puddles? ;)
 
My brother is making a snorkel for his Isuzu Trooper that is similar to an H1 intake. It comes up through the cowl at the base of the windshield and stops there. He made a cap out of a plastic tray that looks really neat. And for water deeper than that, he's got a 3' piece of PVC pipe for deep crossings.

^^interested in this idea, post pics please
 
I don't think the intake plumbing should go down. If you get stuck in a hole it will fill with water (sooner or later) and then you have to disconnect the snorkel to get the engine started and then find a way to empty the water out.

Would an old-style hood work better, where the hood and cowl are all one piece? The snorkel could come out right in front of the A-pillar with a notch in the hood to clear it.

At the lowest point in the intake, put a drain plug.

I'll see what I can do for pics.
