Roof rack mounting bolts.

Check the fibre washers, also best to apply silicone to the threads.

My 120 Prado leaked as well through the roof bolts. I found two of the brackets under the roof lining had rusted too. Not good when a load is going up there. Might be worth checking.

Use Sikaflex or windscreen sealant as they dont set and wont leak if affected by vibration.
Silicone frequently pulls off one side or another if any movement at all.

Mastic windscreen sealant won't set but sikaflex will set the same as silicon.

The sikaflex sealant if you use the correct one remains pliable and allows for movement. I think its 11 or similar number sealant gets used to seal vans apparently.
Silicone sets hard and will pull off one surface if movement is present.
Admittedly not much when bolts are done up but if the rack is on can cause vibration.

11FC sikaflex sets the same as silicone, it is an adhesive/ sealant and they both remain pliable to a degree.

Hi hotfishez,
If you have the racks that bed into a strip along the roof, like the Prado does, then it is a matter of sealing the seat, the fibre washers and new o-rings on the bolt. locktite on the threads and doing them up tight.
My panel beater showed me the problem, as he had to fix the rust first. Maybe a bit of advice first.
