V8 Lincoln LS Coil On Plug Replacement


Lincoln LS

Submitted by: Quik LS

Replacing the COPs (coil-on-plug) is an all to common occurance on early model Lincoln LS. the Valve covers tended to leak oil into the spark plug area, shorting the COPs.

The V8 is easy to do but requires working in a tight space, while the V6 is a little more involved as it requires the removal of the intake (which is listed in a seperate tech article).
