[Vwdiesel] Injectors

[LBaird119 at aol.com]

My first thought is a timing jumped a tooth.  If so, it  shouldn't smooth 
out from 
running, will smoke and have a very noticeable loss of power.  
  Glow plugs will ONLY make it run rough for the first couple minutes  or 
so, then 
it'll smooth out.  Once it's warm, they're irrelevant to smooth  running.
 
  If it's stuck rings or a bad injector, the thing to do is warm it up  and 
go drive 
the snot out of it.  Don't really want to do that if it's jumped a  tooth 
though, 
which SHOULD be unlikely that it did that while just idling.  Doesn't  take 
long to 
pop a valve cover, set the crank to TDC and verify it hasn't jumped a  
tooth.  Takes 
10 minutes and then you know you're safe to drive it.  If that checks  out 
go drive 
the crap out of it.  Could be stuck rings as Mark said or yes,  injectors 
can just 
go bad like that (usually something gets in them in those cases.)   Driving 
hard 
will help loosen the rings, maybe, clear the injectors and blow the carbon  
buildup 
off of your valves, which is also a real possibility considering your oil  
usage, long 
idling, etc.
