Fully Encased Spark Plugs-RUST

[Da1Chief]

c'mon Chief, you know we perform PMS before any equipment would have rust on it...

There was ALWAYS the forgotten FAN Room or Store Room and don't even get me started on the rusted fittings around the Heads from guys that couldn't aim correctly.....

This is now a problem with the new Ford V-10's......This is what the Ford dealers use to remove rust frozen plugs per a TSB.
