Truck cranks but is knocking it’s 1987 6.9 idi will not fire up just cranks
If they're the correct Motorcraft / Beru plugs, you will probably be ok. If someone has changed the plugs before and put in Autolite or anything else, you're probably not going to have a fun afternoon.Glow plugs were definitely an issue the motor is 1984 6.9 idi I don’t think they’ve ever been changed I’m changing them tomorrow what are the chances there all gonna be swollen
Go slow, don't be shy with the penetrating oil, and don't use anything other than Motorcraft / Beru plugs.
