Stopping the SMOKE!!!!!

[de049]

Hi,

I have a real bad problem. I own a RR Classic 1983 model with a Nissan 2.8 TDI engine conversion in 1999. I have it for 3 months now. When i first got it, the only serious smoke coming from the exhaust were at start up and a high revs. Sounds normal to me for a diesel car.

Well, now, thje smoke is toooooooooo much. I have added smoke stopper products into the tank, i even added 1 litre of unleaded petrol as i was told this in very small amopunts actually helps cleans the syustem abit.

Can someone please advise?
