That Egg Fart Smell

[Guest INASNT]

:lol: no not the 1'c u get extruding from your anus!

When i give my car a hard run, i get that bad egg fart smell coming from the exhaust, and i was told it was the cat that was causing the smell! Its a highflow cat, any1 else got this problem??

Would the cat smell like that if its getting ***ed up?

[inark]

i thought most cars do that? my old woo used to... bad... it was embarassing parking next to ppl lol

and yes as far as i am aware its the cat... maybe it needs to be replaced

[Guest INASNT]

the cats only 6 months old!!!

[ed]

I got no problems, and I was told mine was hi-flow cat...

I've only known this smell to come from cars that run LPG

well i run 98 all the time!

it only happens when i do a bunch of 7000rpm changes.

The smell is Hydrogen Sulphide - result of too much sulphur in the petrol, I think. Not a lot you can do about it, maybe change petrol brands.

my friend did say it smelt abit like suplhur when i gunned it infront of him!

I use Mobile 98 all the time!

I might use optimax and see if its still there!

use bp its the shit, u sure its not ur cluctch burning up? my car smells to sometimes except the smell is the clutch

I found a F**ked up cat under my car too, A little tabby, or was it tortoiseshell ?? It started to smell after a few days too !!

Solution: Scrape off cat.

I thought rotten egg gas was sulfur dioxide?

Anyway, it is most likely the result of fuel and a cat not able to break down the amount that is being produced. Try a different fuel first.

See'ya:burnout:

solution...unscrew cat.....enter fkn big hammer and steal"ram rod".....place ram rod in side cat....continue to strike ram rod with fkn big hammer until day light is seen through your meow meow.....take 1 peice of pipe and slide it inside cat and weld with mig welder...replace cat and no more smell...(oh btw this should be done on race cars only )

Or just put a pipe in through the cat.

that smell would b sulphur, sulpher reeks

DONT USE BP, use Optimax

i have no problems at all with optimax

my mate used to always use bp and his car pinged like a b***h! he took it to his mechanic and they drained it and threw it away, said that it is junk and to use optimax...

My car does the same thing, i think it is the fuel. I also use Mobile 8000. Could the problem also be due to too much fuel at high rpms?

hmmmmm

From what I have read, Optimax has the highest levels of sulphur, and BP has the lowest... so I would think that optimax is worse.....

But anyhow, dont worry about the smell Denham, it's nothing.... My womans Astra has been making that smell from new, so I wouldn't worry. I've noticed some cars make that smell while some dont, and all the ones that have had it were brand new.

I use optimax all the time, and when I go for hard drives through the mountains you can smell the cat working, and working hard.. it doesnt smell like sulphur at all.. its actually a good fuel smell, its actually a little bit rewarding

[GaryD]

even my sss pulsar gets it when ive been giving it some stick. thats on bp ultimate too

[Guest INASNT]

thanks for the replys!

I will try optimax next fill up and see what happens! I dont want to gut the cat as i already got a notice from the epa saying my car is 2 loud, so if i was caught without a cat i would be in serious strife!

its not 2 much fuel at high rpm cause it runs a constant 12.1 a/f ratio cause of the safc!

[R31Nismoid]

I get a similar sort of smell but it's not the fuel.

I know where mine comes from...

it's a gearbox boot/seal that's a bit stuffed and after a few 7,000 + RPM changes the smell starts to get inside the car.

Just a bit and you can smell it outside also!

Maybe that's what it is ?
