Leaking Through Boot Vent

Postby Ballard » Wed Nov 27, 2019 8:10 pm

My boot has a minor leak. Traced it to water seeping through the seal that surrounds the boot vent. This is the vent that sits behind the rear bumper on each side of the car.

Happens both when parked and when driven. Not seen or read of leaks in this area before. I assume it's a case of the gasket (BEC8464) failing. Anyone else had this or know how best to resolve it? Do I just need to buy and fit a new gasket or does it suggest another issue?

I have owned the car for 18 months now and check for leaks in the boot whenever it is out in the rain. Yes, I am paranoid. Check my footwells even more often! This is the first time I have found water and I drive it regularly in the rain. The vent has remained undisturbed during my period of ownership.

have you looked at the rubber seal in the fuel filler, they can have little holes in them and the drain pipe can split that goes through the boot to

The leak is on the other side from the petrol filler. It is definitely coming from the vent. I've isolated the area with towels etc. so as to be sure that is where the water is getting in.

Certainly a strange one.

Not heard of this one, maybe wipe some clear silicon round the edge of it to see if you can seal it ??

I think I might have to do that if I can't get hold of a replacement gasket.

Just check the Ariel grommet. Mine had perrished and the water tracked it's way around and didn't look like it was coming from it. Worth checking before you go further.
