    Taped mine, no more fumes. Rubber flaps deteriorate with age and no longer work, heaps of road dust around mine, now it's clean, Regards Frank.

    "Yer pays yer money & takes yer choice" as they say.


    Mine is a '95 facelift & last look the flaps were very flexible & in good condition.

    But don't ask me about the "Lifting Dash Top" problem. %$#@!*&^%@%^$

    if taped up, how would this affect fresh air flow through?

    Well if they are taped up, another thought is that would prevent fumes if they were coming in from the other end, from dash intake/engine bay, as no flow through cabin. Ive noticed the vents them in passenger cars too, seem usually to be hidden under the c-pillar trims.

    For the Dash and the non uv stabilised glue use to glue them on, here is a solution Ive been thinking of doing (yellow tongue plastic and vinyl paint it perhaps?) Key bit to it is using a 90 degree head for the screws (like an air ratchet head)

    I eventually gave up with LR on the dash. Prestige Motors here did not want to help at all, end of & LRA were more than useless.

    So much for LR (UK) destruction testing for months/years in Australian conditions!

    I finished up bunging a few course threaded PKs through it & fitting a Moulded Dash Mat from a crowd here in Adelaide.
    I found out later, that at the time I was having the problem, others were being covered under Warranty as a known problem but obviously Prestige did not wish to get off their bums to assist me.

    Maybe they were hoping that I would give up & pay them to do it if it was made too difficult?

    Later on I needed to replace the front screen & that would have been an ideal time to fit the repair kit which weren't out at the time, but came out later.

    Ha Ha!
    Just luuuve the comments that the air cannot get out if the vents are blocked off.
    Its impossible to keep cats in let alone air.

    There are numerous paths for air out of the car. Down the windows to the drain holes in the doors, and probably through many holes in the plastic sheets over the door inners. Around the rear door rubbers when the door vibrates . Through the many holes that Land Rover leave behind the rear trims.
    You usually block up the rear vents to give the aircon some chance of being efficient in Australian temps and it is one of the first things I do. On dusty roads I put the aircon on "fresh" which pressurises the cabin and dissuades the dust form coming in the back, and only on to "recirc" when a car comes the other way.
    The issue of petrol fumes means the air is getting in somewhere, so it must be able to get out.
    Regards Philip A

    I am guilty of being perhaps a little economic/clumsy in my choice of words. At the risk of reducing the comedy value for anyone who is reading these posts literally, insert “reduced flow” for “no flow”. (Also the term flow also covers the ingress of of cats and dogs, but excludes poodles ‘cause I don’t like them)
    Rather than push out a big spiel on the theory of positive pressure cabins, and resistance controlling air flow, it is worth a read of this for a good summary of whats going on.

    After attending to all seals or doors and rear door, tightening exhaust manifold bolts and replacing all plug/coil leads with new Bosch leads, the smell of exhaust inside the cabin is all but gone.

    Personally, I feel replacing the leads made the most difference - perhaps causing better combustion and less unburnt fuel residue being emitted from exhaust?? I admit I have been negligent in keeping the car tuned and it was running absolutely SH...OUSE for a long time. It lost power up hills, the sound from exhaust was spatter, and fuel economy was just downright rude. Since the lead change, all of these symptons have gone. I now feel like I am driving a real V8 now and wonder what I missed out on,,,,Completely fun to drive now and I can accelerate without any issue and I am confident I can tow with ease now.

    Anyway, this thread has been very interesting - really appreciate your thoughts people.
