Front Hood Vent (window ventilator)

[captahab18]

I noticed recently after having washed the cruiser that I had water coming in down the inside of the cab’s firewall I. Now this is fine and all for washing a car as I can imagine that there is a much more concentrated flow of water when hosing it off. However the same thing happens (though not to the same extent) when it rains.

I started thinking that maybe, just maybe it might have something to do with water getting in from the wind shield ventilator(hood vent). Maybe something has rusted or rotted out which is allowing water to get in.

I suspect it could be the hood vent gasket. I found a post of a guy mentioning his leaking.

So is this also the likely cause of my wet cab?

Also since its there...what the hell purpose does it serve if I cant control it? (other than to leak)

It’s a late 73 -Ahab

Delete this thread please.

Thanks,

Turns out where the hoses attach to drain the vent. It had rusted around the drain holes. Oh and the passanger side hose had split.

After calling my local parts place and finding out this was a do it yourselfer i thought maybe some clear soft plastic hosing from the hardware shop might do. Nay! It all became to difficult to secure it around the rusted drain nozzle. That and I had to bend it every which way to make it work which was no good.

Enter my good friend window silicon. Plugged the worse of the two up completely and patched up around the better one's hole and volia. I no longer have a waterfall trickling down the inside of my firewall.

It now passes the bucket'o water test.

-Arrrrgh after him!..Thas be the white whale that took me leg!

Now Specter here in the USofA has the OEM cowl vent tubes, if you wanna pay for them. I would think they are available down under as well.

eh...im not a everything must-be-stock religion kind of guy. Plus my fix didnt cost me anything but what was laying around.

Ill just be happy if it holds up for a couple of years. That and it wouldnt solve the rusty drain nozzles that the hoses attach to.

Thanks for the info anyway.

So now that you've turned your recessed vent into a bathtub, you will be happy to know that the center plate can let even more water in than the drain tubes, and across a wider swath of your cab. Better get another tube of silly-cone!

It never really was a vent (at least not for my year of crusier, though i have read that some have working ones and some without) ...more like just another place for water to pool to rust.

I think i forgot to metion that i found out through my amazing powers of deduction that its welded and there is no knob to open or close it.

Only one drain hole was silly-coned.

It drains quite nicely and makes sexy slurping sounds like a kangaroo giving a bj mate. Center plate where? Its all welded up and no matter how many buckets of water i throw at it...No leaks, drips, dribbles, or pooling of water to be seen.

Funny they continued to put non working hood vents up to the seventies. Couldnt be bothered to change the molds?

I read a post a while back somebody used that flex hose that's used under sprinkler heads - toro "funny pipe"? Said it was almost the same size and bent nicely w/o kinking. I'll be trying it when I put mine back together, instead of the solid gold priced SOR OEM pipes.

they say we are going to have the most violent storms in years, but thats not hard seeing as it hasn't rained here in over 10 years before this last week. I had forgotten what rain and floods looked like, and i think so had most people judging by the way they drove these last few days.

anyway, we dont get enough rain for water to pool. thats why it called the wide brown land.

as a side note what year did they quit putting the cowl vent of the FJ40's?

Back in the day I sealed up completely my front vent cover (65) with a piece of 1/4" polycarbonate. I used aircraft pop rivets and sealed that sucker up good, never leaked. It looked kind’a cool too, of course I was 19 and my feathered back hair I thought was cool too.

That’s good, because around here you could take your gold fish with you wheeling in that one!

The only brown around here is the the kind with a rust tint! We got green in Oregon:

Its hard to say

http://www.birfield.com/archives/html/landcruisers/1998-03/msg01380.html Reading those threads probably wont help much because it seems everyone had something different to post. So im not to sure when they started welding them to make them useless.

I might go out on a limb and say they quit putting them in around 77ish maybe?
