Problems with airbox?
I go offroading (mudding really) and a lot of it is water. every time i go mudding my filter gets wet. i used to blame it on the location of the air inlet to the box(not the engine) until my friend and i were looking at it and his airbox on his isuzu trooper(which is built a lot like my truck except smaller engine, no limited slip, and being older-still has IFS and intake comes from behind headlight). we believe the water is coming from the crease where the top of the airbox meets the bottom. i have seen a small amount of water dripping from where the tube goes to the engine and have had some rough starts and idling and such (remember going deeper than my doors before i realized i was getting water in there so bad and thought my transmission was f***** due to a slipping feeling and no power until everything had a chance to dry up or wut not). has anybody else noticed this and has anybody thought of a solution? everyone ive talked to says epoxy but i want to be able to open the airbox without having to cut, tear, or rip something everytime. another solution we've thought of is a gasket. would these solutions work? all ideas welcome.
thanks and sorry for such a long post.

are you talking about the top of the box and the bottom, where you open it to change the filter? if so, the gasket for that connection is the filter itself. i wouldnt epoxy or seal that joint up at all, like you said youd have to tear something apart to get to it. do you still have your silencer in? if not, put it back in and that should help some. other than that, theres not much i can think of right now that will help.

One possible "cheap fix".
Amsoil recommends when installing their aftermarket filters that a layer of thick grease be placed on on the mounting surfaces. The grease is thick enough not to be sucked in by the mild vacuum on the intake, and if you use a marine grease it should be immune to washout.
I use an Amsoil filter. However, with my valance off, water splashes into my airbox through the intake hole -- but I don't see it coming in over the top of the filter.

that article that rwenzing posted seemed to have helped me the most. thanks for the help guys but im not wanting to take any cutting type device to my truck like that yet and ive even seen leaves in my air box. how that comes about i dont know. no mods have been done to the box and the silencer is still there.
anybody else have an idea?

i think i fixed my problem. now i didnt have my camera today so ill explain this the best i can and try to get pictures later or sumthin.
for those of you who have looked in depth at the air box: the lower air inlet consists of three pieces. the piece that uses clips to attach behind the headlight (ill call it a flange for future reference), the tube or "silencer" and the air box itself. i took the air box out of my truck and cleaned everything up then took out the "flange". i then removed the silencer and scuffed up the inside of the air box around the inlet hole with some high grit sandpaper. i then applied a bead of plumber's putty (just like putty but is made for wet applications and is ready instantly) around the hole. i then inverted the silencer and put it through the hole backwards so the part that forms a sort of funnel is now inside the box. there was an around the silencer tube that was enlarged to keep the silencer from going in the box, this was pressed against the bead of plumbers putty and then more putty was pused around the seam. everything goes back in like it did stock except now there isnt such a large hole where the silencer slid into the "flange".
this hasnt been tested yet but will be sometime this week. any comments or maybe someone thinks it wont work? i hope i explained it for everyone to understand and i will try to get my camera soon.

How close is the inside of the tube to the other side of the box? It won't restrict your airflow will it?
I just removed my tube. I see no advantage to putting the tube in backwards -- why didn't you just leave it out?
Ediit: Nevermind on the tube length. It's now shorter on the inside, isn't it? Still don't know how that will help you not have stuff get in there.

^^^i inverted the tube cuz i believe i can get a better seal this way. yes it is shorter on the inside. i didnt want the putty to be plainly exposed and now with the longer tube outside there is less of a chance of water pouring in from the top. if you look at your setup with the silencer in the right way then youll see how it slides into that "flange" that snaps in behind the headlight. there is a pretty big hole in that area and the longer length of tube goes past it and is actually sitting in the "flange". if youve seen your hood lining after going offroading you know that a lot of water can splash up into the engine bay and i think this is where my problem was coming from.
one more thing...wut if i were to drill another small hole almost directly under the silencer in the airbox? the only other hole i see in my airbox is in the upper left-hand corner as viewing the box from the fender and is no bigger then 1/4". do you think the second hole would help or hinder?
