Yes it's a timer. 11v glow plugs. The others were too, just shorter.	pctek (84)

In a DIESEL the smoke is not truly related to a gasoline engine for smoke/diagnosis. In a DIESEL now :: Blue smoke from oil burning is rare as a diesel runs on oil anyway and it isn't likely to smoke blue until something's really REALLY wrong. You MAY have a dose of Diesel #1 (Winter grade) in the tank too and it has very low cetane rating as it has very little paraffin in it, which is what the diesel needs to run well. White is UNBURNED fuel that has been compressed in the cylinder and did not combust and has been released into the exhaust as a condensed cloud of fuel - however this color can also be from very late injection timing or urinating injection nozzles. Low compression CAN cause this condition, but it also makes the engine really hard to start all the time. BLACK is over-advanced injection timing or leaking injectors, but may also be from too much fuel that is partially burned but went through the whole compression-power cycle. Low compression will not cause this problem. And as far as unusual, diesels are much more reliable and thrifty for miles-gallon ratings when compared to a gasoline engine performing (or trying to perform) the same work. BTW: In defense of pctek, although I also believe that she really doesn't need support or protection - is that the smoke from a diesel engine is biodegradable. It is consumed by the same friendly bacteria that also eats sloughed-off tire rubber. You don't see great piles of tire dust on the side of the road - do you? Same for diesel smoke. Breathe deep and feed your internal friendly fauna. Congrats, pc - I'm glad that the longer glow plugs did the job. Now go haul something big and heavy. (What size were the water cylinders?)

What I have done on old diesels that were pigs to start was bypass the timer and just put in a push button switch. I have seen a bus with a turbo timer used as a timer and it was adjusted for 15 seconds of heat. A lot of diesels do not even need any heat I have an Isuzu engine bus which hasn't got heat since a solenoid burnt out. It starts on about 2 fan blades of rotation even in winter so I haven't bothered getting another relay. My service truck has an electrical heater muff instead of glowplugs on the air manifold which is disconnected. Dont really need heat in Auckland. Sudland a different story even the diesel freezes and waxes down there. My neigbs had a bighorn that was a pig to start he went to change the glow plugs and 2 of them broke off in the head turned into a major.	prefect (6291)

My neigbs had a bighorn that was a pig to start he went to change the glow plugs and 2 of them broke off in the head turned into a major. bus engines are generally DI injected which start a lot easier in the cold. the old nissan is IDI injected which are heavily reliant on glow plug heat to start, even more so due to lower compression from the worn motor. typically what happens is people don't realize one or more glows have failed and will resort to "double glowing". problem with that is it overheats the remaining glows which expands the tips. then when you try to get them out the tips jam and break off.	tweak'e (69)
