Hi All

I know it's been tackled before - however I have a different situation here and doing the precautions and maintenance read from my research.

I have a zd30 engine in a 2000 GU - it has a DPchip diesel in it - and it blows smoke while on Boost - however I also noticed that the boost goes flat - seems to be leaking somewhere, but I am not sure.

So what I've done so far

1. replaced oil and all the filters
2. Used a bottle of Injector cleaner

I am planning to do is

1. Change AFM/MAF sensor
2. check all pipes see if there are leak
3. might ring a diesel mechanic or tuning shop

my question is
am I going to the right direction or doing the right precautions? or do I have to do something else
please advise
