Glow plugs and injectors
Is there some point, time wise vs totally stuffed, that the glow plugs and injectors in a ZD30 Di should be changed?
I am on the 140+K mark with my Patrol, 2005 GU IV. From what I gather they are still the originals.
If the plugs should be changed, any suggestions.

From what I have been told here, glow plugs around 100k and the injectors when ever the car feels like it need them. But the plugs need to be metallic tips, not the original ceramic type.

Thanks. I had a feeling they had to be changed but I could not find any reference to the timing of that.
I know they weren't changed at 100K so looks like they are a bit out of date.
Is that 100K also applied to the metallic ones or just the ceramic?

100K seems to be the norm for glow plugs. I replaced mine at around the 110K, they still work fine and looked ok (no tips missing) when I removed them.
I replaced mine with genuine ones.
If you are going to replace them with the metal tip ones, it would also be a good idea to modify the timer circuit. Have a look at this thread.

Don't know regarding the injectors. From what I understand they are non serviceable??. So I guess they just get checked then replaced if need be??
Then do you only do the injectors or should you do the pump at the same time?

Been doing a bit more reading on this.
Seems the 100K is the suggested point for the glow plugs.
As for the timer I was getting the impression this could be used for both metal and ceramic to reduce the after start glow time.Though I am not sure if I got that correct.

The factory control time for the glow plugs can have them hot for up to 5 minutes or about 65°C. Every ZD30 head I've seen, has cracks at the glow plug holes. Coincidence? I doubt it, I have a 30 second timer on mine.

Yes the timer can be installed with the original type plugs to reduce the time they are on for.
