drafty

Post by meek.tv » Mon Apr 07, 2008 11:42 am

on a recent trip on the motorway i had to go a bit quicker than i should have and noticed a draft coming from the sunroof opening in the aft. is my aft likely to be blowing off or is it a common occurance? ive never noticed it before

Hiya Meek,
Dunno bout the sunroof, but, I noticed that my doors(front) try to open themselves if I go over 80ish.
So much so that you can get your fingers in the gap at the top. needless to say I dont go over 79 often!
I think its a physical impossibility for the AFT to blow open, Although I could be wrong.

Hiya meek, have read this somewhere recently on here too and there was quite a bit of advice coming back from the guys on the forum. Can't find it right now and will try searching again.

If memory services me correctly I think someone suggested that if you have the top part of the tent zipped open (so that the fly screen is visible) even with the AFT down you can then get a draft coming through...so maybe check your tent zips :?: :)

your correct with the aft, the pressure when driving is enough to lift the front up so that air can get pushed through, its normal on an aft and yes keeping it zipped up will help.
regarding the doors yes they do have a tendancy to open when moving at speed.

I've noticed that when pushing over 90 it gets considerably colder, esp in the back. Much much worse when the top hatch is flipped back.

I imagine the tintops don't suffer this but interesting to find out.

I think the general consensus with the opening door phenomenon was that it seems to be exaggerated with the bigger wind deflectors...

Cripes - I've not noticed any of this. Mind you it could be because I putt putt along at 65mph and also because I don't notice anything anyway these days (apart from the occasional slip 8) )

I think there's little chance of the roof lifting at speed - the motors "over centre" to lock the mechanism when fully down. It is possible the rubber seal is being distorted though :-k

Hi, i drive tintop must admit i haven't noticed any of this..
I did used to feel a cold spot in a few of the commercials i used to drive, plus door squeaks especially the double openers in the back. (but i would expect that with older wagons).
I assume the double layer of carpet, linings & seats on the Bongo or any other MPV would suppress any of the aforementioned traits suffered with the hollow amplification on commercial vans.
Plus the fact i crank Slayer on the stereo!! :twisted:
I also have the larger clear wind deflectors... the door latch adjustment might have something to do with the gap thing at high speed.
Though looking at the catch assembly i see no option to adjust this..
On the whole my doors don't pull open either (bearing in mind the doors appear quite light)

Just one more thing.. i foolishly went through some deep flooding a few months back (it was deeper than expected), & though the wash tore my intercooler air scoop off i was expecting the foot step to fill.. it didn't. :shock:
All in all.. a surprisingly tight drum! :D
Cheaper by comparison to a race horse...

Cor, I could use some advice on this. A few of my plastic 'plugs' are popping out but I can't undo the phillips screws (without fear of stripping the head) in order to get at the plugs and pop them back in with some Alardite. How did you get the screws undone Keefy?

Keefy - that's fantastic info and thanks. If you are OK with it, what I'll do for the general benefit of members, is (maybe on a new thread - I'll PM you a heads up) take a pic or two of the problem (which has not reached the serious stage yet) then post them so we can be 100% sure we ar etalking about the same thing). We can then work through what needs to be done. This would make a useful and simple factsheet as I can see this being one of the things anyone keeping an ageing Bongo might face at some point, esp. if (like certain sections of teh membership) they will insist on having meetings in windy exposed locations at unseasonable times of the year. No names, no packdrill but Jetskier, BDC, DBO and others could probably shed some illumination :lol: :lol: :lol:
