Black smoke!
Hello,
Bought my Alfa V6 3.0 12V engine at last. Collected the car from a very sunny Surrey and drove it 70-80 miles home without a hitch.
However, not satisfied with this I had to tinker and discovered that the engine produces a reasonable / lot of black smoke when revved hard. I did
this the next day so the engine wasn't exactly warm. The vehicle came with 2 SORN's so I think it hasn't been used in a long while
as well. The smoke is not an oil burning induced blue and it didn't stink of burnt oil either. Any idea if this is serious?

It's just fuel.

Yep, if the engine was still fairly cold the injection system would still be on warm-up enrichment, and be throwing a fair bit of fuel in, which
chucks out lots of lovely black smoke. As long as it runs cleanly without misfiring there are no worries at all.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

Just unburnt fuel. Try it when when its hot..
As Dev says when its cold it bungs in loads more fuel than needed.

Don't over adjust it lean, I have dealt with 2 of these engines that have burnt out pistons due to partially blocked injectors/weak mixture
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation
