hi, new to this but, i just find that I got water ingress from god knows where....wet is around third pillar ,on ceiling liner on left hand side. strange thing is that there is no holes,damage on gaskets or any rubber there....car is usually tilted other way so no reason water to even get there. but still ,soaking wet. Anyone had a problem like this ? after few h. of working and removing stuff I am thinking that is : - antenna on roof.... -back wiper pipe line damaged-- is still working and spraying lots of liquid.... -water finds way through hinge bolt.... i have put back all together and cleaned all gaskets and will wait and see if that will dry out. for your well problem...there are few factory holes there....just pop plastic cap off and you will be ok. also you should have 6 mm thread hole for spare tire fixing rod.
