After driving the Griff I always smell very strongly of exhaust fumes, doesn't matter if the roof is on or off. My car is a pre cat so expect it to smell a bit potent but its getting to the point where i even get a bit of a headache! Do they all do this or is something amiss? Cheers, Simon.

Someone has suggested makine the pipes longer, but how long is longer? Are we talking a couple of inches or am I likely to have someones eye out the next time I reverse??

I made miine better by taking the rear lights out and using a mastic sealent when replacing them.
Also make sure the boot seal is in good nick.

I also read about someone who cut and shaped some dense foam and fitted it above the inner wheel arches in the boot.

Mine was also better after being set up by MA, he reckons the smell is the hydrocarbons.......

Of course if the hood is off ( as it should be) then you will still get a bit.
Mine used to make me smell alot, but last wednesday (after nigh on 300 miles in one day) I only whiffed slightly.........

If your manifolds leak at the 4 into 1 bit - as most apparently do - then you could well be getting exhaust gas in the cabin.

Ive fitted exhaust extensions to my 4.0 Precat Approx 5" LONG. It does reduce the exhaust smell slightly , but does not cure it. It may help if you turn your internal fan switch off!

Forgive me for intruding onto your forum - but after being out in either of our wedges (400SE + SEAC) my clothes always stink of petrol and its either with roof up or down.

Hi folks, Have also the same problem with mine, really puts me of driving it unless i can take the roof off, think its potentially dangerous being gassed slowly, would also like to sort mine if anyone has any ideas ! Regards dave S

I’ve never had an exhaust fume problem, and you guy’s who do appear to be in the minority (in the Griff scheme of things). So I would guess it’s a fault with your cars. Most likely to be the exhaust system leaking that’s some how getting into the cabin. Another possible, do you have speakers in the rear vents….

60maxx whereabouts in East York’s are you, I’m near Brough and haven’t seen any Griff’s round here for ages.

Cheers,

Simon.

It could be gasses leaking from the engine bay into the cockpit from a number or sources. Check the seal around the big black 4" pipes against the bulkhead (they carry the air from the heater matrix on the pax side to the vents on the driver's side.)
There is another hole on the pax side near the rad - One big one near the alarm siren (not the one just in front of the rad - that is the intake for the cabin blower motor). Make sure that is sealed.
Of course you also need to address the cause of the fumes in the engine bay, but that might stop a lot of it coming into the cockpit!
Another thought - mask up the vents on the parcel shelf and see if it is better. If it is, your boot seal might need replacing.
Just a couple of ideas.

In my experience the manifold nuts have a habit of loosening and should always be nipped up every serice time. My 4.0 was particularly bad, but the 500 is much better (it also has sealant round the rear lights)

Has the heat shield on the inner wing started to deteriorate? If so it could be that the manifolds are burning the inner wings.

I'm not sure if this is true, but I'm informed that there was a recall or mod for precats to stop this happening after a few early ones caught fire!

Hi K77,you may well have a point here, when driving mine, seems worse on a hot day, and the smell does remind me of glass fibre resin rather then exhaust fumes , any ideas on the modification ?

Ahh, now were getting somewhere.

I did have this problem and to me it smelt like cat pee. It was the inner wing seams getting hot below where the heat shields stop short. On close inspection you could see the glass had been burning.

I first fixed this by folding a few layers of aluminium foil and sticking it over the seam with silicone sealant, but at the next service Joolz replaced this with much neater aluminium tape, problem solved.

Cheers,

Simon.

I have the extended tail pipes, but if it rains I arrive smelling of damp carpets and mould.
