I am the proud owner of an ‘82 XJ6 series III. I love the car, but unfortunately have a gas smell in the car and definitely while driving with the windows down (causing headaches). I extensively read through various forums, but nonetheless wanted to ask the communities’ advice. This is my first post, so bear with me. Happy to join the jaguar family!
Driving with the windows down generates an under-pressure due to which the gas fumes of the boot get drawn in. I tried to fix the vent flaps (‘cowbell phenomenon’), so the fumes shouldn’t be drawn into the cabin too much anymore.
However, issue remains that there is a serious gas smell in the boot. I used a gas detector to pinpoint any leakages / location of the fumes, while the car was turned on (engine running) and in Neutral. This is what I have found:
- heavy gas smell coming out of the fuel turnover switch and or the hoses attached to it (2500+ ppm)
- very heavy gas smell coming out of the hole of the internal bodywork via which the hose/pipe coming from the fuel turnover switch goes to the left tank (5700+ ppm) - I think the rubber that should close off the hole has some openings in it. But nevertheless, is it normal to have such a gas smell coming from there?
- heavy gas smell coming out of the same hole on the other side, going to the right tank (3100+ ppm). Similar story.
I’m wondering what the issue could be here. There are some candidates like e.g. a leaking tank but before I dive into that, maybe the collective wisdom of the community can tie the 3 measurements together to one specific issue/phenomenon?
I’ve added a picture to clearify the specific locations in the boot.
Thanks in advance!
