    I have a 69 Buick Special Deluxe and I just figured out that a leak in the trunk is filling up the rear right quarter panel. I mean I just washed my car yesterday and it is actually still sloshing into my trunk. I'm really not sure why this is happening. My dad has had like 5 68-69 GS/Skylarks and he's never had this happen. Is there a plug or drain or something that got plugged? Thanks

    For clarification... it is getting in through the little part of the trunk that has a hole that goes into the body. It is the right rear quarter behind the wheel well.

    Are you sure your rear window isn't leaking?

    Sounds like a lot of water jus from a carwash.
    Sorry, no info on the drain hole thing. But it sounds like you need to make one if there isnt.

    There is probably a drain plug, but not an active drain, like under the doors.

    What hole in the trunk lid are you refering to, the trunk lock?

    My skylark leaks into the trunk as well, on the right side no less. On my car there is a plastic plug at the bottom of the fender that can be popped out but I choose to drill a small hole in the plastic plug instead (from under the car looking at the fender). Now it drains pretty much as quickly as it goes in. I did that over ten years ago and haven't noticed water in the trunk since.

    I see you're in Nevada, so water in the 1/4's there may not pose the same problem it does other places. Still, the trunk should be dry. It's either coming from the urethane glue that holds the back window in or the seal around the trunk jamb, or from a small hole in the wheel well.

    My bet is the urethane glue for the rear window has dried and pulled away from the pinchwelt and is allowing rainwater to get in. It's not that hard to use a sheetrock knife to halve that glue from the inside, and thereby remove the rear window intact. Then clean up the pinchwelt area with a wire wheel and treat any rust. Then get the special primer for it. Later take the car to your favorite glass shop to reset the window.

    When I did this on my former Electra I bought a tube of POR 15 seam sealer which worked on pin holes I had from putting the repair off. Then the primer was a few bucks and the glass shop only hit me up for $60.00 to reset the rear glass. And the problem was solved. I believe the entire project was under a hundred bucks and the peace of mind was priceless.

    I didn't live in Nevada 10 years ago, besides as mentioned car washing can do it too.

    There are drainplugs in the wheel well,pull them out & drain it.If the metal is'nt treated you need to clean & paint or it will rust.I lost 2 quarterpanels due to the previous owner dropping a ton of empty shellcasing in the trunk that plugged those even with the plugs removed.After i cleaned them out,they just slowly rusted away.
    If you dont believe me look at my cars restoration thread.:pp

    And all that water & moisture also rotted the trunk from underneath.

    I don't want to hijack your thread, but I have a 64 'Lark that has water pooling in the front foot wells....after washing the car. Anyone have any idea how this might be happening...? Front windshield seal is new....:Dou:

    I had to put a new coat of seam sealer over all the seams in the cowl of my 78 Estate Wagon to stop this. And you may want to check the inner cowl area if the 64 has one.

    Thanks Man! I just took a screwdriver and broke it off and the rivers opened up. It looks like a little vent or something but it cracked as soon as any pressure was put on it. Thanks again man!

    Remember the problem is just managed not solved, but that'll take care of it for a long while.

    John D- thanks for the recommendation.:beer

    What product would you recommend for sealing the cowl seams?

    I used POR 15 patch, which came in a tube, and is concentrated POR 15 paint. It's the consistency of putty and adheres like epoxy. This stuff can go pretty far and it lasted over two years till I consumed the tube. This will fill small holes if you have any. But I also would recommend seam sealer that can be bought at any automotive paint store.

    i do not know if this applied to our cars, but i owned a 78 omega that had a small/slot opening between the lower rear quarter and the wheelwell housing on both sides and that is how the trunk drained.
