A mate was following me the other day and noticed black smoke coming from my exhaust, checked the oil level and the oil is down. Funny thing is its had a new engine and only doen 3k, shouldnt be burning oil should it! Any opinions on here?
Its a gsi by the way, cheers.

Well it shouldn't be smoking after 3k...
How did you run it in? Redlined from cold every day?

black smoke = running rich
white smoke= burning water
blue smoke = oil

i always let it warm up first, ive never redlined when cold. the previous owner had the engine done though, he said he let it warm up but you never know do you.

If it is running rich, how can this be fixed?

Im guessing u have a X14/16XE 
Go to vaux and ask to get it compression tested. Or buy one and do it yourself

buy a compression tester. screw it in the spark plug hole on each cylinder one at a time. take the king lead off and crank the engine untill a reading can be taken (couple of revolutions of the crank). record the readings should be similar. if one or more is low do the test again with a teaspoon of oil in each cylinder. if compression changes then this will suggest piston rings are shot. if not i would say valve stem seals. c tester will cost you about a tener from halfords etc
