an led light will only indicate power is getting to the glow plugs, you really need an ameter and monitor the current,
a quick / easy test is to unplug each glowplug , attach a wire on the positive side of the battery, and briefly touch the connection on each plug inturn , there will be agood spark/flash, if the plug is ok, if it is open circuit there will not be anything , if you have an ammeter, you could measure the curent usually about 8 amp per glowplug,
if you need to get a defective plug out , make sure you get a hexagonal long socket, if you try using a 12 point socket you are most likely to round the plug off if its tight ,

I tested all the glowplugs and replaced them all I just wanted a true reflection of when the plugs were powered up

changing the forth plug will most prob solve your problem , as has already been said it hasnt been changed because its the difficult one to get at , either change it or live with the 30 seconde of smoke
Can this 1 plug cause this tho not exactky cheap to replace this last plug but sort of doesnt explain the blue smoke
Was going to order a pcv but is there a way to tell if my one is faulty
Would rather spend the £20 on something more useful if mine turns out to be ok
Thanx again for the help & advice it is all greatly received and looked into as much as I can

mat the very least you can do is test to see if the glow plug is ok, very easy to do using a lenght of wire , and yes a single cylinder not firing for a few seconds is going to give you some smoke,
if it is running ok when up to temp , i dont think you should be to concerned , although a full set of healthy glow plugs will certainly make starting easier when it really gets cold,

after using Autodata to find the Air intake temp sensor i took it out and cleaned the end it was a bit black and horrid like the manifold used to be before i removed the EGR
fitted back and started car had a little puff of smoke then nothing not even on first revs
anyhow i also come across this on Autodata and wanted to see what you thought

according to the data for the glow plug ,R= 0.8 ohm each glow plug should be drawing 15 amps
