Right floor wet

[DwayneOxford]

'83 720 King Cab with sunroof and AC.

Took off cowl grille, all clean.

Got 2 gallon oil jug blocked up tight under heater.

It seems to catch most of it.

Has rusty streaks behind under heater.. Not seeing how to include pic.

You can see that the drain on the far right side is clear? Gently pour in water and confirm that water drains out behind the front right fender and does not drop by the heater.

 

Another possible leak is the windshield rubber seal. Could be anywhere along the top, side or bottom on the right.

 

Check heater hoses and water cock on the passenger side of the heater assembly.

 

Dwayne.... were you on 720 World???

 

[DwayneOxford]

Thanx Mike,

All looks well under cowl grille.

Got fairly new windshied and gasket.

It's rainwater, no antifreeze.

Sure got me.

Yup, miss 720 

[datzenmike]

Oh... the rubber door seal?

 

Could still be the windshield. Use a garden hose and slowly wet it starting at the bottom then the side and finally the top. Leave enough time for it to get in and start dripping.

Mine leaks in an unaccessable area  in the cowl area. If you stick your head up under the heater core with a light you will probably see a rusty area. I could get my leak to stop with thickened epoxy for a while but it would leak again a few months later. Garage kept now so i try to avoid the rain but before next respray I will dig in there and weld it up. Good luck 

[DwayneOxford]

datzenmike will do. 

bottomwatcher I'll get mirror and light and look. There are rust streaks on carpet behind/under heater. Sure no rust visible anywhere under cowl grille. 

I'd post pics but only see "insert image from URL" option" ??

What up Dwayne, a ole 720 World member.I just replaced my door window seals,water was coming through there but didn't get inside the truck.It kinda messed up the inside of the door panel.It made a few of the panel clips get lose.I bought new clips and repaired the panels so that the clips would keep the door panels secure.This is probably not your problem.Also when these seals go bad,it will make your window rattle when rolled down.A good URL site is Imgur.com.I use it.It's free...

The title of this thread makes me imagine some kind of weird game of Twister. Right floor wet...left rocker rusted...back ujoint sloppy...

Thanx, Tommy, glad you still kickin and keeping 720 up. Bought this'n while back, Only bad place in cab was sunroof drain. They picked bad way to terminate it. Rusted thru above cab mount and I never caught it till I got home and caught a glint when I opened door. I brought it on out and put bug screen on end. How does imgur work? Photo storage?

There are 2 body seams that need seam sealed on the cab, you have to pull the fenders to get to them.

Photo storage?Just go to the site and sign up.Then you can load your pictures  and videos there and send them any where,also they have some pictures and video's to see.My wife has a 2004 lincoln LS  with a moon roof and one of the drain hoses stretched and came loose and was leaking at the inside part that comes down by the door from the inside top .I had to take apart the top roof part and pull the hose back to the fitting and secure it with a cable tie.These Lincoln's have a history of this.

Just realized we are talking about a 720, same deal, sorry no pics.

 

Also sunroof is a suspect as well. 

[DwayneOxford]

Thanx ]2eDeYe, sunroof drain is on left side, already fixed it.

EDM620 posted this pic, it is the corner under the cowl and fender. 

I think there is a similar joint on the 720.

[DwayneOxford]

Thanx again ]2eDeYe. Sure can't see anything amiss under cowl vent. 

I'll report back when I take fender off.

[bottomwatcher]

Pour water in cowl and see what happens.

[DwayneOxford]

Took fender off donor truck, nothing under there to assist access to problem

[DwayneOxford]

Well, my 1st "image insertion" didn't go real well. Anybody know why can't put in straight from computer?

[datzenmike]

There's a size limit of 4 MB.

[DwayneOxford]

Is that why they gotta be from a URL instead of from computer storage?

[datzenmike]

I just load them to a picture hosting site but if you size the ones on your computer to under 4 MB they should load.

You gotta stick your head in and look up from the inside - it's the seam between cowl, fender and firewall.

The 720 construction will be similar for sure.

 

[DwayneOxford]

Thanx EDM620. Is pic inside cab with everything removed?

[EDM620]

Yes everything is out in that pic, as that was the stage in my build. If you set a trouble light or a flashlight into the cowl openings (remove the wipers then the cowl cover - the slotted panel) you can probably see if there's light visible. Have someone move the light about to confirm.
