When i go on a "fun" drive i get an egg smell in the car, am i right in thinking that this is a sign the cat is knackered?
its fine when normal driving, i did over 300 miles yesterday and didnt get any smell.

Egg smell is definitely the cat. No two ways about it

However, it does not necessarily mean it is knackered - yet

There are generally two issues than cause this. Either the cat is running too cool (unlikely) or the car is overfuelling - quite likely

Any other signs of overfuel? Do you have a dump valve?
Beware. Once the cat starts to complain you don't have long to fix the root cause before it turns it toes up!

Eh???

Eggy smell is always from either
a) Catalyst
b) Last night's ruby and 4 pints of Grumblebelly's Aud Trouser Flapper

Greg
The knackered O2 might have drowned your cat in Optimax and done it damage :(
You can't easily tell without an emissions test

so either a new cat or de-cat is in order then??

Im not argueing with your reasons or suggestions.

All im saying is from personal experience ive have encountered the smell, not from the orofice you refer, from my car, with a decat in place....

Discuss!

Greg btw, will have a heatwrapped aussie for sale soon, only a few months use :D

Sorry dude, looks like you got a 185 so no good i beleive.

You've got me Mat

The egg smell is sulphur dioxide and AFAIK it's only a by product of the catalyst process

If you've got no cat then I'm blowed if I can see where it comes from. Unless you've got a bit of broken off cat wedged somewhere lol

I believe a 205 Aussie will fit a 185 though. Just has a spare stud hole :wink:

Could it be either a clutch smell or from some sort of strange brake pads? :?

The 165 with the Pagid pads occasionally smelt of bacon!
