I had not driven the car close to a month or so. When I first started her up, I noticed that the glow plug light did not come on and did not think much at the moment; As I proceded to ignite and thought (Low battery?) dismissed it. when I started it the light stayed on. (Well that's odd I thought at the moment) followed by some unusual knocking which made me think a glow plug had left or it is on its way out as the noise slowly vanished. The light stayed on for more than 8 seconds or so. I then decided to turned it back off.

Once I turned It back on. Everything back to normal including the glow plug light. (This was late in the afternoon after I had returned from work) then late last night I decided to give it another try after the car had cooled down. The glow plug light worked normal but the light knocking was present.

Erebus just turned 102k and the plugs were replaced at about 70k more or less.

Could it just be that one or more plugs that are leaving?

Your input as always is greatly appreciated.

Thanks.
