Title: Stinking Cat
Post by Jonnycab on Feb 17^th, 2010, 1:33am

Had a council taxi MOT test today (yesterday now ;)) & they have now started emissions testing on all vehicles....something they stopped doing a few years ago, after they had to pay out for damages caused to a petrol Merc when they, thinking it was a diesel, blew up the engine by revving the c**p out of it ::)

Anyway, I was waitng in the canteen next to the testing bay when I suddenly heard the guy revving the c**p out of my engine.....I'd estimate that he was giving it close to 5000 rpm ???.......He did this a couple of times for about 20 seconds each time ???
I thought for petrol engines, only 2500 - 3000 rpm was required.

After the test was finished he called me into the testing bay & told me it had passed with no problems :D. I commented about the fact that I thought he had given it too much welly during the emissions test & said that, as far as I know, it's only diesel engines that have to be revved that high for the emissions test & did he realise mine was petrol.
He said he only gave it between 2500 - 3000 rpm. I said to him that I thought it sounded like a lot more, but he denied this......liar >:(

Anyway, at work tonight, I noticed an occasional, real bad rotton egg smell (passengers probably think it's me, but are too polite to say anything ;D) & it seems to be coming from the cat ???....Is it possible he may have damaged the cat in some way by high revving the engine for too long ? :-/

Must also add that there has been alot of rain today & I've been through a few floods...so is it possible that the cat has started making this smell from getting a good soaking ? :-/

Anyone got any thoughts before I go to storming into the council offices & start demanding compensation for damage caused during a council vehicle test >:(.... ;)

Might add though...the car is still running fine & there isn't any symptoms of blockage or rattling from the cat as yet :)

The smell is caused by high sulphur content in the fuel Happened in the early days of catalytic converters until the fuel producers brought out the low sulphur fuels which we buy today. Seems like you might have got a bad batch of fuel . High revs should not affect the cats in fact I would have though the opposite would apply getting the cats nice and hot and therefor making them work more efficiently. Others no doubt will have other opinions on this.

No, it's defo the cat ;).... I don't need incontinence pants just yet ;D

The cat didn't make any nasty smells last night ???, so I'm wondering if maybe some c**p got dislodged when the guy was giving it some & has now passed through. Or as Snoopy says, maybe it was a bad bit of fuel going through, although I haven't noticed any lumpy running (engine or bowels ;D) & I steer well clear of supermarket fuel ;)

Anyway, I've just stuck a bottle of Cataclean in the tank, so hopefully that will sort the cat out :)

[]....I think you could be right ;)....I rarely go over 3000rpm & I suppose that is good formula for carbon build up. Maybe the council tester did me a favour & I ought to go & thank him for nearly blowing my engine ;)
