Greddy-Matt Posted April 23, 2012 Share Posted April 23, 2012 Hi Fearing something serious, I'm after a little help please, I've noticed in the last month or so that the Z is stinking something awfull after it's been driven, when you pull up and get out of the car there's a really acrid / seriously hot smell from the rear, definately from the exhaust and you can't smell it from inside the car (it's definately not your normal exhaust fumes sort of smell). It started a little while after I had a Scorpion exhaust put on, I put it down to the coatings and oils from manufacturing etc in the exhaust burning off, however, I'm about 1000 miles down the road and it's still smelling pretty strong. The car's not smoking, and it's not using oil (I check the oil every week and it's not moved from the max mark since changing the oil six months ago!) so guessing it's not lunched piston rings.... The coolant level isn't dropping, and engine temp doesn't fluctuate at all once warm so wouldn't have thought it's a head gasket, so bit flummoxed really, could it be running too lean? Any ideas? Oh I have checked for placcy bags dead animals etc stuck to it, and nadda. Any ideas??? Quote Link to comment Share on other sites More sharing options...
Keyser Posted April 23, 2012 Share Posted April 23, 2012 What CATS have you got? they can smell bad when the start to go. EDIT: Could be the zorst touching something and melting it - rubber mount maybe - if it only started after the new zorst??? Quote Link to comment Share on other sites More sharing options...
Greddy-Matt Posted April 23, 2012 Author Share Posted April 23, 2012 Hi Ive got standard cats at the moment, I wonder if it could be those, she's just hit 41'000? I'll have to get under the car if it ever stops raining to see of its hitting anything, it's VERY close to diff but I cant see much further back than that.

Dblock Posted April 23, 2012 Share Posted April 23, 2012 sounds like the cats. If its a sulphury rotten eggy chemically burny smell then its most likely your cats. Quote Link to comment Share on other sites More sharing options...
Greddy-Matt Posted April 23, 2012 Author Share Posted April 23, 2012 Hi Not eggy, but chemial / burning for sure, guess I'll be doing the sports cats/de-cats sooner than I thought then! Quote Link to comment Share on other sites More sharing options...

daveparkin Posted April 24, 2012 Share Posted April 24, 2012 If its not eggy, its not likely to be the cats. If its an acrid burning smell, my money would be on something rubber/plastic burning on the new exhaust. Like Chris said, check all the exhaust mounts.

Willy P Posted April 24, 2012 Share Posted April 24, 2012 I had this when I got to the new forest after hitting a plastic bag on the m27. Got stuck to my mid pipe and burnt and smelled for weeks. It was worth it though for the pacman feeling of eating a plastic bag ghost. Quote Link to comment Share on other sites More sharing options...
Greddy-Matt Posted April 27, 2012 Author Share Posted April 27, 2012 Thanks for the suggestions guys, I've found the problem now it's dry enough to get under the car! I was looking too hard for the problem. The issue is with the exhaust, it's touching the plastic diff cover and it's melted a blimin great hole in the side of it Can I remove the diff cover, will it cause any issues?

I was so close Yes your diff will get hotter That cover is an air scoop thing that pulls air over the fins - Mind you I've seen several Zeds without them! Do you track?

I don't track but not known for being gentle on the old girl either, maybe I can "modify" it Quote Link to comment Share on other sites More sharing options...
Keyser Posted April 28, 2012 Share Posted April 28, 2012 That's the best idea - failing that you probably won't notice any difference with it off. Besides we all have water cooling in the UK at the moment Quote Link to comment Share on other sites More sharing options...
