exhaust fumes :(

[The AJP Griff]

I know this has been covered a few times before but the search isn't working at the mo and I wondered what the general consensus was on my problem. I have exhaust fumes getting into the cockpit big time if I have the window down,but nothing with the windows up. Are the fumes coming in through the window or being pulled in through the rear vents do we think? I'd love to hear from those that have cured this problem.

Usual checks are the boot seal and make sure the rear lights are sealed.
I know it doesnt tie in with your windows up/down thoughts, but maybe with the windows open the air is being pulled through the boot ,over the arches and into the cockpit.

Cheers Ant,I was hoping someone would say 'boot seal' I guess I could try masking off the rear vents to prove it.

You could try that Mike, but dont forget the apetures over the wheel arches only have carpet over them in the cockpit.
I think some cars have high density foam blaock pushed up there from the boot side.

Cheers Ant,will do. Off out in a minute with the vents taped over and a couple of old towels stuffed over the arches

This might help

There's a link at the bottom of the page for a link to a donation site and fitting instructions/templates

I've used this solution and I've not had the problem since.

Thanks for the link Colin. I've just been for a run with the vents sealed off and the towels stuffed over the arches and there were no fumes at all-great stuff! I'll try adjusting the boot lid/seal first and if that doesn't work I'll try the scoops Thanks again for the help guys

I thought Cliff had knocked something up that fits under the rear of the car that solves this problem Micky

Oi that link did not work for me until now Gollum !!

And you needent start Pizza Boy !!

I remember when I fitted the mod wise boot opening kit and had to run wiring from the boot to the passenger door lock,the area over the arch was jam packed with foam,was a right bugger to remove,mines a 95 so wonder when they started to build them like that to minimise the vapours reaching the cabin ?

Clives scoop does seem like a good option.

I've posted on fumes before. Exactly the same problem with fumes getting sucked into the cabin. Because my 500 has ACT manifolds with no cats, the fumes are totally unadulterated. Changed boot lid seals, but no difference. Have bolted in the cat pipes, and big improvement. I guess this is because the cats are cleaning up the emissions before I breathe them in. My next venture will be the boot scoops ( from the Griffith pages). As soon I get back off holiday, I'll fit them and post back with the results.

Cured mine yesterday I adjusted the boot shut so that it gave a tighter seal at the rear trailing edge as it wasn't pressing down firm enough on the seal and it almost cured it completely.What I then found,using a smear of vaseline along the seal as a 'tracer' was that the seal sat further back at one small point because there wasn't a high enough seal location in the fiberglass, so I put a short length of 1.5mm cable underneath the seal to make the seal more'proud' at that point and it now seals perfectly-zero fumes

Result.. How did you adjust the boot shut? In the past I've tried repositioning the boot lid gas struts but with little success so I'm very interested in your boot shut procedure.

mike has a well proportioned backside, so he probably sat on it.

Cheeky git Fordy
Dave,to adjust the shut so it was tighter I simple moved the striker on the boot lid a little further up and therefore the lid will sit lower when it is held in the latch. My lid also has 2 little rubber pads on either end of the trailing edge preventing it shutting too close to the body and cushioning the lid closure.

[davep]

^^^^^^^
Cheers for that Mike. As a fellow fumes sufferer, I'll have a play with the striker plate. My boot lid also has the pads, perhaps shaving a few thou of them might allow the trailing edge to sit a bit lower/tighter. I've also removed sponge filling from the two air ducts between the lower edge of the hood and rear boot lip, which allows better air circulation with the blower on. A previous owner probably blocked the vents up when the blower motor went U/S.

+ 1 for the boot lid, there was a soot streak on the underside of my boot lid that showed exactly where the exhaust gas was getting in, adjusted the latch and no more soot

Same here,I have soot deposits on the trim oround the boot edge and also around the carpet surrounding the vent grilles
