1987 740 trunk leak tire well

After significant rain I can find a bit of water in the wheel well on the right side of the trunk. Also I think there is dampness near the right trunk hinge. It feels damp when I place my hand on the arc shaped part of the hinge and feel toward the front of the car. It looks like there are some seams in the body that meet there. I caulked (just slathered it on hoping for the best) but the problem remains. Any ideas? There is not a lot of water - maybe a tablespoon after a day of rain so the wheel well just gets a bit wet. I see that there are some balck drain tubes near there but I think the leak is above that juncture of the tubes - I caulked them too.

Yep, like James said, dirt will will do it, especially things like pine needles.

The easiest way to find leaks around the trunk lid is to lay a strip of newspaper over the seal, close the lid and see if the paper will slide out easily. Work your way around until you find the problem area. If the problem is all along the lock edge then you can adjust the lock. Adjusting the hinges is very awkward and not worth doing unless you have a serious gap. What you can easily do is raise the trunk seal slightly in the problem areas. Lift the trunk seal off the lip and then put a filler strip on the lip (like a few layers of plastic tape) or, as I have done, put a bead of silicon sealent into the rubber seal, set it down all the way onto the lip then raise it slightly and let it cure before closing the lid.

If there is a sunroof then the drains in the corners of the sunroof tray may need cleaning. If debris has gotten into the rear drain cavity (where those hoses are attached) then the drains may be plugged.

My '90 744 TI leaks through the trunk seal when the seal gets dirty - which it seems to do all the time. I check and wipe it off every time I go into the trunk.

Check the rubber seal and the surface on the trunk lid where the seal touches.

Some people lie in the trunk with a flashlight and have a friend spray the car with a hose. (The friend must be trustworthy and not have a warped sense of humor!)
