Glow plugs

[Giggsy]

Hi All,
I was looking at my glow plugs and have noticed that two have a small tip (just a bit fatter than the lead from a pencil) and two are at least twice as fat and the heater tip twice as long, have they put in glow plugs from a 2.7 instead of a 2.7tdi? Which are correct? I have pics but need to go home to up load them.

cheers Ryan

Hi again,
Any second now as if by magic Mav will post a pic of the two types of glow plugs fitted in my t2, which are the right ones. Ta
