Ok.. quicky and i hope its nothing but ive noticed that some black (possible carbon deposites) exiting the exhaustpips after having a little rev.. pop pop pop .. blackstuff..

Anything to worr about.. i can provide a pic if needs be

Looks like the thing behing gets chicken pox

Pics would be good, or you could drop it in for us to have a look if you like?

Don't worry it's only....

2 pics attached, the black marks are on some kitchen paper.. put next to a £20 for size comparison

This is after about 10 revs to 4k

PIcs are poor.. Ill try get some others when its light and when i get home after drivin the car

Ive tried again with the origional paper. But wont get a desent pic

Cold engine im guessing?

Looks like the usual sut what blows out when you give your car a handful. But if Youve started the engine cold and doing this it will be the condensation blowing out mixing with the black smoke??

water temp its self was still high and id been home 30mins so not stone cold.. If seen it come out of tuned cars... but standard??

Petrol or Derv.

If the latter, a bit of smoke and soot isn't unusual after washing the car etc.

Its petrol,

I stated before it was standard.. Thats not technically true. I have a BSH Filter fitted.. (AKA loud throttled goose)

Just wondering could it be condensation and carbon mix? just being free'd from the exhaust?

That is what it is, remember in the engine you are burning hydrocarbon fuels, so one of the by products is water, it is always there and is usually expelled as steam so you don't notice it, however like you state, when the car has been stopped for a while, the steam left in the exhaust condenses into water and what you are seeing is that water, along with some soot which has been trapped in it, being blown out of the exhaust by the sudden rush of gases. I wouldn't worry about it, especially if there is no sign of it after you have been on a longish run and got everything nice and hot.
