Hey I just bought an old 1981 Nissan Patrol diesel swb to get me started with 4x4, the problem with her is the amount of smoke that comes when I fire it up. I press the glow plug for a good minute or two yet she still blows smoke and starts sluggishly. Now I'm not familiar with diesels and I bought this car to get to know the ins and outs. Should the glow light turn off when the plugs warm up? It starts fine and clean after driving it for a while. The glow plugs have just been replaced, do they need to wear in.

ok matey two questions to get started on the prob, color of smoke ? black or blue/gray? if black its a fuel . if bluey gray ifs burning oil , get a compression test on it will help in solving the prob, remember u cant use a standed car tester on it , so dont try, they can go BOOM , not good

also does it smoke why driving? ur injectors could be up for renewal as well (think howsy said this as well )
injector pump timing should be pretty easy to check your self ,and if u got a manual on the Patrol, it should be in there , to corect the pump timing is fairly easy as well and should be in the manual aswell , how ever a specialist will be needed if there is any probs with the injector pump (this often meens BIG bucks and BIGGER bucks if u try to do your self when u dont have the right tools or knowhow)
no afence howsy on any think u said , and i agree if a person is not mechanicaly minded or knows nothing about motors then a specialist should be sort,

Smoke on startup can be caused by condensation to a degree but in a lot of cases it is inaccurate injector pump timing which becomes more critical when the engine is cold. try also one of these engine flushes in case your rings gum up a bit. There is one that makes all sorts of claims advertised in 4WD monthly. Have the pump timing checked by a specialist and strike it off your list.
