1987 740 TURBO SUNROOF LEAK

Had a really bad rainstorm last night and my sunroof started leaking. Anyone know how to make adjustments to make the fit tighter ? I can't seem to find the adjustment screws mentioned in the Haynes book. Thanks. Bill D. Staten Island, New York

It's not a matter of making it fit tighter, the seal is not meant to keep water out. More likely one or more of the drain tubes are clogged so water is backing up in the internal gutters.

Drain Holes:

[Response: Tony Stanley] If its a factory fitted sunroof the 'seal' is not to meant to be a perfect seal and the gutter should carry away the water. The chances are the drain is blocked, or the hose is kinked. They drain to the front and rear. The front goes down the A pillars flowing out behind the front wheel, the rear goes out the C pillars and down the rear quarter panel, flowing out behind the wheel. [Don Hodgdon] The drain holes for the front sunroof drains are just below the leading edge of the front door. If you feel under the rocker panel, there is a "D" shaped hole that the water from the sunroof and the fresh air vent (at the base of the windshield) drain to. they can be clogged with undercoating. Water from the sunroof's rear drain holes goes back through plastic tubes, down the C pillars, through the trunk (you have to peel back the carpet on the sides of the trunk to see the hoses) and out through a plastic fitting mounted to the lower quarter panels, hidden on the outside by the rear bumper trim. Debris from the rear window drains clog up the plastic fitting which can flood your trunk and cause the sunroof drains to back up. You can disconnect the hoses and use a shop-vac to clear out any stubborn debris. [Editor] To clear blockages in the tubes, use a long cable with a non-snagging end so you can rotate it within the tube as it is pushed down from the sunroof. Compressed air might either compress the blockage or burst the tubes apart deep with the pillars.
