Video L300 cold start. Fouled injectors?

Hey guys it was a tad cold this morning around -5C (23F) so I filmed this little clip cold starting the van. Have not started it in a couple days. I haven't had my injectors properly cleaned either. Since my idle is rough even after the van is warmed I feel like I'm due for an injector rebuild. I'm wondering if the 3 or 4 puffs of white smoke are attributed to the injectors or the glow plugs?

Appreciate the info, stay warm out there Canadians.

Just did my glow plugs and mine smokes worse than yours on cold starts...

Now you're just trolling. That's about the nicest engine startup I've seen below freeing. Yes, there's a couple of puffs of blue (along with the usual black), but nothing unexpected.

My old Isuzu would spew white smoke for about a minute at those temperatures, and it was 3 years old with 20,000km!

My only advice would be to get the engine revs up to 1000-1200rpm as soon as it starts, and use the idle speed knob to keep them there until the temperature gauge starts to move. It'll idle much smoother since the alternator is trying as hard as it can to recharge the battery after running the glowplugs.

Weird, okay thanks everyone. Guess I'm doing something right in the maintenance. It still idle's rough so I'm sure its due for an injector clean. I'll troll somewhere else now....

You might be due for an injector clean, but don't expect it to substantially improve your starting.

older technology diesel its normal probably because the combustion chamber needs to warm up to get a good fuel burn
