  Take a sniff of your smoke.  If it smells diesel-like then it's probably 
original injectors and a new set of injectors will probably make a HUGE 
  If it smells like burned oil then either a ring broke or broke loose, or it 

has gasser oil in it and a ring or two has stuck.

  I've seen this quite a bit.  Sometimes it seems to be a cylinder that's 
burning oil and sometimes it's a leaking injector or heat shield.  Diesel 
then mixes with the carbon, a bit of leakage bubbles through to mix 
well, and it ends up looking like oil  More often than not it's been a poor 
seal at the heat shield.  The nozzles are real buggars to try and change 
in those cases too.
  Really dirty air filter could cause negative pressure in the crankcase 
and cause oil to pull through and burn as could a clogged valve cover/screen.
