CJ heater
Mate I think I saw from your photos that you have the late model heater fitted in there.
If the CJ8 isn't your daily driver, I'd recommend sacrificing a weekend to pull the heater and sort it from top to bottom. They're not complex beasts.
If you go over all the seams in the plenum box (that's the one directly under the cowl vent) as well as my tip below you're sure to nail the leaks.
While you're there, pull the main heater box and strip it down. Clean out the half a gum tree's worth of leaves that've been accumulating in the heater since the Eighties. Throw in a reco'd heater core, new pull cables and springs and trim the seals on the plenum door flaps so they move easily. It will work good as new.
If you haven't got the time to do all that, the hot tip on your leaks is some sneaky little bastard screws. Fix takes half an hour max.
Take the cowl cover off and you'll see some other screws under it that hold the plenum box up against the cowl. These screws are sitting in little wells that love to trap water and once the screws go a bit rusty they wick the water through like a sonofabitch.
Take the screws out one at a time, replace them with new, clean the little well and wipe some silastic into the well hole before replacing the screw. Then slap some duct tape over the top of each screw once replaced. Not too big a piece, just so you can't see it when you pop the cowl grille back on.
Put a small dab of silastic into the cowl grille screw holes before replacing the grille. Run in some clean screws and my bet is you're sorted.
Have fun....
