strange smell

[letemlaf]

hey guys

i notice that occasionally when i park my car after driving home there is a strange smell comming from the exhaust.

i have no idea what it smells like, only that it doesnt smell like oil and theres no smoke or anything.

im just worrying if it is something i should worry about or get checked out

thanks!

do u smell it when ur drivin or stopped?

Have no idea if it's the same smell, but my R30 L24E running ULP does a similar thing. It doesn't have a cat, so it could be sulphur oxides. Maybe your cat has died.

i smell it when i stop driving, mainly when i exit the car and head for the house after work, but once i smelt it at the lights with the windows down.

doesnt seem to be comming from the engine bay only the exhaust.

i have a brand new hi flo cat about 1000km old

check ur diff

look at the back of the housing where the plug is. sometimes there is fluid residue and it smells bad when it starts to evaperate from the heat.

[letemlaf]

good point, ill check the diff after i drive it next, see if it smells the same.

btw, i need to change my diff oil...what do you recommend?

I'm not sure about this but could it be the new cat ?

I mean - the stuff in the cat becomes active because of the heat so maybe when it's new it starts to smell ? Only a theory.

I have redline shockproof heavy for my mechanical when I get around to it..

It is most likely your new cat "bedding in"......give it a couple more weeks and you may find that the smell will disapear.

check its not ur power steering fluid leaking. that can smell funny when it heats up

ill keep an eye out!
