hey
ive had my gq diesel about 3-4 weeks.
We went up the beach last week, and alot of the way way pretty soft sand
high range most of the way, and a few spots 2nd high and foot to the floor
the guy following me said it was blowing alot ( more than normal) black smoke.
I followed the missus home today and everytime she put her foot down to accelerate, or overtake , there was constant black smoke

the car had a new injector pump fitted 2-3 months ago ( cost the guy over a grand) . A mate told me perhaps the new pump wasnt tuned or something with the motor and running rich, causeing the blow by crap more than it should. could this be true?? or anything else cause it.
i done an oil chane last week .
it starts sperfect, u barely have to turn the key , runs smooth, will idle all day.

thanks
