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.

Could be valve stem seals or piston rings?

Done a compression test?

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

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
