> Dear List,

I replaced both of mine on my Iveco engine with bronze plugs. With just a
little TLC, the old one screws off and the new one screws on. I soak my
plugs in a small citric acid bath to chemically clean the threads of any
residue. Knock on wood I have had none of the problems discussed in this

Iveco uses these plugs on engines that as emergency backup in the field,
like for cell towers. I have no clue why they are not standard on a engine
in a marine application.
