finally got around to changing the three duff glow plugs on my 220 [ remember, I tested their resistance to find them all OC ] got cylinder two out easily then struggled a bit with number three ...... cleverly was able to fully unscrew number one then found there is no room to extricate it from its orifice as a block connecting the top hose is in the way ....... didn't have time to drain down etc so renewed two and three and screwed back the old one into number one ...... hell of a frost here tonight so will be interesting to see how easily or difficult it is to start in the morning with two thirds of the plugs good ..... thanks all for your comments and advice by the way over the last week or two ..... let you know how the engine fires up in a day or two then promise that's the last of glow plugs, at least from me
