When i start my dt up for the first time of the day it is very rough on start up, spluttering and white smoke then fluctuating idle, almost like a misfire. A minute of letting it sit and sort itself out and its fine, starts perfectly every time for the rest of the day.
Im thinking air ingress or crappy glow plugs?
Any other ideas?
Air igress.will happen when hot. Whip plugs out and test. Probally find a few are dead
Ahh yeah that makes sense, whats the way to test? Just whip them out and switch them on and see if they come on?
The correct way of doing it is removing them and testing that they glow with a 12v power source. By the time youve got.them out might as well stick a new set in.
Yeah im doing a bosch conversion soon so ill whip a new set in while the pump is off, may aswell seeing as though winter is on its way...
You'll need to check all the connections from tank, to engine bay and make sure nothing is perished etc. Jubilees tight and all connections/bolts on the pump tight
Just use a DVM and measure the resistance...
Sticking injector? Mine misfires when i first start it but clears if i give it a few revs
