hi all just having a few starting problems, in the cold mornings the glow plug light is coming on but they are not priming.
i have tested the plugs by crossing them on the battery and they all work fine.
is there a fuse or something that could have gone.

second problem when i removed the glow plug from the first clyinder on the drivers side it was covered in oil, i cleaned it and tryed it again but when remove it was once again covered in oil right to the thread.
is there any reason for this, could it be head gasket or stem seals?

any ideas
