• Hi all,
  
  I just purchased an 86 Jetta turbo diesel from my neighbor for $800. He rebuilt the engine top to bottom, new injection pump, turbo, clutch, everything. The car has been idled and only driven down the street and back.
  
  The car starts hard and pours white smoke out of the exhaust and is clacking (injector clack) rather badly. The engine smooths out slightly when I pull the advance cable but never runs well.  The smoke reeks of unburnt diesel.
  
  In my experience with old OM617 Benz diesels this is either an injection pump timing issue or the injectors themselves. He replaced the injector nozzles however, did not have them pop tested or balanced.
  
  Assuming he timed the pump correctly, I should be looking at injectors correct?
  
  Any insight would be greatly appreciated!
  
  Thanks!

• I would check the  pump timing including cam  first

• Pump timing, and get the injectors pop tested.
  
   I normally have my pumps pushed as far against the motor as they will go, they seem to run the best there.
  
  If pulling the advance makes the motor quieter, I'd give the pump a nudge towards the engine. If you don't have the proper tools to check timing (borrow from neighbor??), you can set the pump by ear. Loosen the bolts, crack the lines at the pump and rotate.  Snug up lines, start car, tweak pump as necessary.  My diesels have pumps with unknown mileage, I've never been happy with them set to spec, I wind up advancing as far as I can without resetting the pump 1 tooth off (which is my next step on one motor)

• Does anyone know about the timing belt cover update for the 2011/2012 Amaroks??? Yes I need a new engine as the serpentine belt went through the the engine... Thanks...

• Get clear fuel lines. Air in the fuel will cause white smoke.
   Has the water separator been removed yet?

• There is still a section of clear fuel line where it goes into the pump. I replaced the fuel line from the tank pickup to the fuel filter bypassing the water separator. I had air in the lines when I first got it and took care of that right away.
