I'm wondering why my B-engined 1979 BJ40, after a cold start, runs great for about 5 seconds than starts to shake rattle and smoke a bit for 15 seconds or so ( does depend on the amount of revs) after this little show it's all 100 points. Does my car have a "after-glow-system?". I've checked pressure with manual pump, that's OK.
Cold start - poor running BJ40

Dude try plugging the poor old girl in at night. A new block heater will do wonders to help starting and you will save your engine a hell of alot of loading without oil.

ps a heaters about $30 and 1/2 hour install

It's called the "super-glow system" on the diesel TLCs.

Ok-Ok the wife-thing is getting a bit personal... and doesn't tech-qualify. It is not extremely cold in The Netherlands, -5 degrees centigrade is about the coldest is winter. However, when I say shake-rattle and..... I do mean she's about to give up, unless I rev the engine above let's say 1500rpm, which must hurt after a cold start. It's definitely not the EDIC, since I disconnected it. Now please tell me more about the block heater, I've never heard about that!
Thanks for the response

do you have a NAPA over there? if so purchase the block heater and insert in the #2 frost plug from the rear, your engine will love you for it...

Wayne,
No NAPA in Holland (that I know of).
Len,
A block heater is an electric heater that is installed in the engine water jacket (usually in place of a frost plug) and, when plugged into household power, preheats the engine prior to starting it. In Canada and the USA many trucks and cars are equipped with one of these even when new from the factory.
Obviously, you'd need to be parked in a driveway and near an electrical outlet to use such a device and I know from travels in Europe that only 50% of cars actually have a driveway to park in.
Check each glow plug individually as well to ensure that they are all OK. You shouldn't NEED a block heater at -5 C yet but if some glow plugs are bad hard starting is going to happen as well. If you feel you want a block heater I'm sure folks from Sweden or Norway are familiar with them.

The glow plugs may not be the problem at all. If your injector nozzles are all gummed up or the injectors themselves are shot then they could be the problem. First do a continuity test on the plugs i believe they should be around 5 ohms or less.

Cheers.
if its the injectors, it will be continuous bad running even after the engine has been warmed up, so if it coninuously runs bad at idle its the injectors, or a clogged fuel system, or air in the fuel system. If its just running rough at startup before the engine is warm, its the glow plugs, one or more of which isn't quite working properly. Or a combination of both.
If the nozzles are dirty\gummed, The spray pattern on a cold start will have large globs of unatommized diesel. Without sufficient latent heat in the surrounding cylinder wall the diesel will not flash off properly and will start very hard . The super glow system does not leave enough heat in the cylinder to support such a start. (Poor flame propagation).So do the continuity check on the plugs if they check right they are ok. If not replace them. Also check to see if the plugs are filthy. Maybe the heat cannot make it past the s***e.
