Toyota 4WD Surf Owners

Gidday lads and ladies.
Just got a question or two.
My kzn185 1kzte had to have its turbo seals and compressor wheel redone on which I actually had another turbo lying around for one funnily enough, which was nearly brand new. On which I deleted the egr system even though it was blanked off already. Now she ran alright the first few times after the turbo was replaced then I left her for 48 hours and on which I started her up again and her sounded fine, but at idle with a few revs a loud ticking sound comes and gets louder with revving it more (does not sound like it's from the crank) ... And white smoke comes out more as well.. But at idle black smoke.... My feeling is its a fuel problem. I'm thinking of draining the tank and starting from scratch what would you all suggest?
