I think they all do it. I have a theory but could be way off... I wonder whether the residual pressure in the fuel rail on shutdown weeps by the fuel injector needle(s) and leaves a small amount of excess fuel sitting in the bore(s) which burns off blue on next startup?
I know that blue smoke usually indicates oil, but my 2.4 does the blue puff at startup yet doesn't use/lose a drop of oil > 110 XS Double Cab |

I have an engine heater on mine. If I use it, there is absolutely no smoke. So it's not leaking down injectors. If I don't use it, and it is proper cold, it smokes quite a bit. Zero oil consumption, so it's not that either.
It just is what it is. |

There is steam as well, sometimes it can seem to be what it isn’t depending on lots of factors. It’s quite normal anyway No Guts, No Glory.

Changed all the plugs. It was a nice straightforward job.
Biggest worry was them being stuck in. They weren’t in very tight in the end. Only 2 of 4 were working and the other two took ages to dimly glow. She’s starting smoother, and less smoke when cold. Thanks for everyone’s input. |

Glad you got it sorted.
Glow plug change is on my list but every time I plan to swap them out the weather is crap. The only good thing is that the current glow plugs have been soaked in Plus Gas since Boxing Day. Jim |

Soaking them and other fixings like that is well worth doing that’s for sure.
I’ve found some things before very tight, left alone, and put some penetrating spray on for days to soak. Gone back, and it’s undone no problem. Most of the time you can just tell when not to push your luck on something when it’s overly tight. No Guts, No Glory. 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

If you have a plug carbon up which can be usual enough if the glow plugs has been failed for a bit , soaking with some form of release oil for as long as possible is about your only hope of success..pool it in the plug head cavity and run the engine as many cycles to normal temp as you can before attempting.. if its jerky and releases in cracks stop and try lightning a bit before reverting to undoing etc etc..
My last stuck plug was actually clear of the retaining threads and still cracking as you tried to release it..still required a lot of patience and rotating back and forth while trying to exert some upwards pressure to extricate the thing ..😫 When removed i used an appropriately sized twist drill to remove the carbon from the bore |

All great advice, one additional bit. If you set a torque wrench to the tightening torque of the glow plug. Then use that wrench in reverse to remove the plug, you can be sure you are not over stressing the plug. Obviously this only applies when the threaded section is still engaged. But does give you more confidence when applying initial torque to break the plug loose.
