Hi Guys,
Replaced the glow plugs in my 2H for the first time yesterday and noticed that the way each of the old ones came out was quite different, some fairly clean, some oily, some coated in carbon and some dipping oil.
I know that you can tell a bit about petrol engines from the used spark plugs, and I wasn't sure if you could do the same sort of thing with glow plugs?
I had a look at some other threads and they said the oil on the plugs is nothing to be worried about. I just thought it a bit strange that they were all quite different.
Plugs in the picture are in order of cylinder 1 through 6
