Source of leak on driver's side identified
Wanted to share with the community about getting closer to fixing a water leak on driver's side. Through method of elimination, I identified the source of the leak to be the top corner of the A-pillar. Here is the full story.
Previous owner alerted me about occasional leaks he experienced on driver side during rains. The car was always parked in a garage and he did not drive it much, so he did not bother fixing it. But he did tell me about the water getting inside during rains.
I confirmed that was true when I took my cat through car-wash: I felt water dripping on my feet by the time I got out of the car-wash. I quickly dried everything inside, including the floor mats, and decided not to drive the car during rains (which are very infrequent in my area, so no big deal) until I figure out and fix the source of the leak.
Outside inspection was inconclusive. There were many suspects: seals around the windshield; wiper motor pit, etc.
Yesterday, I asked my wife to use water hose and spray water at different areas, one point at a time, while I was sitting (almost laying) inside looking for the source of leakage. That's how I identified that the water is coming through an apparent whole at the top of the A-pillar. see where the arrow is pointing on the picture.
I am thinking about applying clear weatherproof sealant in that corner, to close up the hole. Unless there are other suggestions?

I usually apply some mastic to the screw when fitting.

I blocked up these A pillar roof drains both sides with mastic. Very good plan. The OEM idea is that roof water runs down between the trim and the steel A pillar and runs to the inner chassis flat plate under the wing - where it pools as there is no obvious exit path, and rusts that part.
Blocking the drains makes no difference at all to anything else, or AFAICS to getting wet when opening the doors. Whilst water will enter through a trim screw, more dangerous is that the A pillar gets rusty as the space gets partially blocked and water hangs around and rusts out the steel.

Hi Greg,
I guess you could block the A post drains if there are internal leaks in the internal channel but first I would try blowing them out to check they are not blocked.
The drains are one of several carefully hidden around the XJS bodywork. Andy Harvey has an excellent guide to them on his website: http://www.justxjs.co.uk/admin/resou...why-part-1.pdf
I cleared my drains as Andy recommends and got no end of muck out and I think they all run freely now.
Good luck,
LeeP
