Hey guys just joined and thought id share this post incase helps others ***x1f44d; had leak coming in front under glovebox A pillar looked like vapour seal or windscreen leak but no...also rear footwell soaked atleast 2 inch of water in heavy rain. Anywho after months of searhing found it ***x1f601; turned out to be the roof bar ***x1f644; rubber seals had perished and rain water ran down all pillars filling the passenger rear and front footwells which has now broken my yaw/speed sensor under passenger seat carpet ***x1f614; fml. Anyway i hope this helps someone as it puzzled me for months ***x1f44d;

Thanks for posting this. I don't have water issues now, and my car is mostly garaged, but this is something I should check. My roof rails are removed... been long enough that I don't recall how I sealed the underside. The trim openings are covered with racer's tape which holds up remarkably well (years).

I'll be ordering 6, 7, 8. ... about 60 bucks on ECS for both sides.

Those don't actually seal any water out of the body. You can achieve what you're after just by putting some RTV on the screws that attach #3 to the roof.

Those gaskets simply isolate the roof rails from the body and prevent noises from the parts rubbing together as the body flexes. They might need to be replaced for cosmetic reasons since the hinge point where the flap that covers the mounting screws is quite weak and could fail when you go to access them (a couple of mine did, was fortunate enough to find a touring to grab gaskets off of in the u-pick yard for spares), but the area below the plastic trim strip is where it needs to actually be water tight.

When I had the dreaded glovebox drip on my 2001 it was the front right sunroof drain that was off. Car would stay dry when parked nose uphill, but when parked nose downhill it got soaked. Reattached and secured the sunroof drain and all was well. Sunroof drains being off or clogged are a top cause for water leaks.
