soot on rear of car

[sportie]

I seem to be getting a fine sooty type deposit on the rear of the car. Especially around the nearside and the numberplate area. It's easily wiped off but the car being yellow it always shows up.It appears worse now I have fitted sport pipes.

The car runs fine other than losing a little water; Any ideas what might be wrong? or do they all do that sir!

Is it using any oil? May alternatively be indicative of an over-rich mixture.

It's used about a litre of oil in 3000 miles so I think thats about right/normal?

Mixture sounds promising, can it be rich on one bank of cylinders? i.e. the nearside in my case?

It's quite normal - so nothing to worry about.

Our car did it when we 1st got it, stopped after the next service, but I've been told by a few people that it's quite normal....

3000 miles per litre is about right. Sounds like your mixture is a bit rich. As Olly says, probably nothing to worry about, but if you're concerned it might be worth taking it to your dealer/friendly independent and getting them to hook up your management unit to a computer.

Oil sounds about right. I'd be more concerned about using water. Mine started to use a little water it eventually manifested into a major radiator leak. From what I understand the water is a sealed system so you shouldn't be using any at all. IMHO

Using up to 1 litre per 1000 miles is not unheard of, and still nothing to worry about... Will go lower still if used hard at a track day....

Thanks for the replys guys, I shall get the dealer to check out the mixture when its in tomorrow having a new starter motor.

The dealer has pressure tested the system twice and reported no leaks, I have also changed the pressure cap but it still loses water.

Yesterday I found a damp patch on the panel under the rad on the nearside, will get them to look for a third time.........

I had this on mine but only on one side. Took it to see Andy and he pointed out that one of the sports pipes stuck out further than the other so one left a deposit on the bodywork and the other never!

All fixed now though.....

3000 miles per litre of oil? I'm lucky to get 300!!
