Its just frustration on my part. Have been trying for the third day to get the last glow plug out of this vehicle. It is in like concrete and dont want to sheer it off.So I keep moving it back and forth spraying PB blaster and heating it. Then when I contact MB parts the person is the biggest drip you would ever want to speak to.He speaks in monotone and is a nasty SOB. How they have people like this working in areas where there is customer interactment is beyond me.
