Help !
I have had my 280sl manual since october....However I have noticed when I pull away from a back wall at the rear of the car, BLACK SPOTS on the wall .
I left the car running for a while before I placed a piece of card board at the end of the exhaust , Black Spots once again appeared on the card board with some dark running fluid !
Anyone have any Idea what this could be ? I smelt the card board for petrol but no signs of petrol ....Just black spots with black running fluid / water !
Could this be a sign of oil in petrol ???
Is it dangerious / serious ?
Please advise .
Kemal
PS; Or maybe this is normal for a classic 69 car !

Sound like your engine is running rich.

The same thing happens to my car after letting the car sit for a while. I agree could be running a bit rich but as I recall when I posted the same question, most of the experts told me not to worry about it

Kemal,
It is quite normal to get the water (condensation) at start up.
It is a by-product of combustion. Also, the black spots are carbon but its from the rich mixture at start-up.
Nothing to lose any sleep over :)
What part of London???

Thank you very much ...
I try to drive my SL at least once a week for a few miles , as Ive read , to keep it alive .
So you can see my concerns on the above matter .
I'll just have to remember not to stand behind the exhaust in the summer months in white trousers ! [ While the engine is running of course ! ]
I'll sleep better now.....Thanks again.

Hey Kemal. My car does a bit of the same thing -- although it is more pronounced in the colder weather. Definitely not a good idea to stand behind the pipes with white trousers! It sounds like you back into your garage? I do that only when I lower the hard-top on and it makes an awful mess. Rest of the time, with the garage door open, the splatter is not too bad.

Your car may be running too rich.
The most effective way to address this is too pull the injection pump and have it rebuilt. I did this to both my 230SL and 1972 911T. It will make a big difference. It's not that hard to do, just take your time and have patience.
Fairchild industries and CA did me right as far as having the pump serviced.
If your car is running too rich it means your oil may be getting contaminated with fuel. That not good for your engine.
Best of luck with your 280SL.
Cheers

Hello Kemal,
90% of injection pumps sent in for rebuild are not defective, just out of adjustment, according to the rebuilders.
If you can find a good knowledgable technician you may only require a slight adjustment. You may have to educate yourself so you can do the adjustment yourself or inform someone else. This site is a good place to start.
Drive your SL first to find out if it any other problems arise.
