I have the tall air cleaner housing. It has the permanent inner
screen inside the throw-away filter.

How do I clean this? It seems to have some crunchy stuff in
there (when I squeeze it)

Thanks

The secondary filter you're talking about is another piece of power-robbing emission equipment. From what I've heard, the charcoal(that's what's crunching inside the mesh) stops doing it's job after a while anyways. I removed mine years ago. I'm not sure if you can clean it, either.

CanmoreK5 is right...the one I have was glued in there so hard I bent the air cleaner trying to remove it. Since I have to repaint mine anyway, I'm going to melt the sealant before trying to get it the rest of the way out.

Hi Dorian

I will slice it out...guess I'll use a small cut off wheel on Dremel.
Thanks for the info !

305 or 350? TBI or carb? My 87 with TBI 305 has nothing like that. Did the 305 and 350 have different air filter housings? I'm curious, since this spring I want to make a dual-snorkel ram-air type of housing. If one holds a larger filter, I think that's the one I want to start with.

GM offered an optional "pre-filter" or somesuchthing for about $40 if you ordered a new truck. I wonder if that's what this gadget is that you guys are talking about?

The two air cleaners were somehow offered at the same time, at least on the K5's with 350's in 1986. At least thats how the auto parts store listed it. There is a short one, and a VERY tall one. My '83 K5 (305, AC, Q-jet, 700, 3.08's) had the tall one also. Not extremely rare, except when you want one. I picked up one two. FWIW, the air inlets are the same on the tall and short version (truck only) so you just need the snorkel off either size when you get the big filter housing. FWIW, I believe even the bottom half is the same, ONLY the lid is taller, now that I think about it, I'm positive.

I don't think this could be a "pre-filter" since it is after the regular air filter does its job. I believe the prefilter is what I have seen on some diesels...replaces what the plastic snorkel attaches too, and actually can suck air from behind the core support, so if crap was in teh air, it might suck half as much as if it was getting it all THROUGH the core support. Looked retarded to me.

So maybe by making a circle the diameter of the housing out of some sheet metal and riveting it into the housing, I could use a taller (less restrictive) filter without having to scrounge the junkyards. Any opinions?

Well I cut that little charcoal filter out the other day, and my truck sure runs better and feels like it has more power.

someone told me it is there in case there is a backfire or something like that, i removed mine and you could feel a difference
 
Personally I like the clean look, so I just waited until I found the right one. Carb stud is a pain to find too, but of course ready-rod will work fine. Just go get the taller of the two air cleaners that the local auto parts store lists for the K5 (305/4 barrel) in 1983. You can set it in your housing, and see how much you would have to make up. I'm betting 3" or so.

Cool! I'm adding a second snorkel at the same time, whenever I can get around to doing this, so the whole thing will probably look a little hacked up. Thats OK though, it'll match everythin else under the hood!!

I'm going to be adding the second snorkel too. I've done it on my car and my dads truck. Just get a 2 or 4 barrel air cleaner from the wrecking yard, preferably bent, so as to be cheaper. I drilled out the spot welds to remove the snorkel from the bad cleaner housing, my dad cut a whole secton out of the housing to accomplish the same thing. Had a friend spot weld mine back on, my dad welded the whole section into his. I think my way was easier FWIW.

Since I don't have a welder I'm planning on cutting a little extra metal off with the 2nd snorkel and riveting it on. It's gonna be a hack job, but some sealant and paint should clean it up nicely.

How about just drilling through the spot welds that hold the snorkel on, and using those holes in the just removed snorkel to drill the ones in the soon to be dual snorkel housing, and rivet that way? No reason to add metal if you are going to rivet it.

This is why I like running my hare-brained ideas past other people. Someone else is always sure to see my flaws and present a better plan!! Thanks for the hint.
