So since i had the head off i figured i'd have a go at removing the glow plugs. #1 cylinder has one broken off from a previous owner. Engine did not have a light for it which i thought was strange. I didn't notice it right away when I pulled the intake, I caught it later. Someone hose clamped a good glow plug to a bracket under the intake and connected it. Viola no light. Anyways i used some trans fluid, a mini inductor from work an milwaukee impact driver.
