I hear the powersteering pumps are defective. The Valve cover gaskets are prone to leaking, The Hot Coolant Control Valve (HCCV) goes out on almost everyone, and the most expensive problem is the coils go out.

The valve cover gaskets & the coil problems are usually one in the same. If the gaskets leak long enough oil will pool in the boots of the coil plugs. Coils cannot be cleaned, and will have to be replaced for about $70.00 per X 8 =$560.00 if all need replacing. There is however no need to replace all just because you replace one. Check each coil to see if there is excess oil. My recomendation is if one valve cover gasket needs replacing , be proactive and do both.
I also bought a 2002 Lincoln LS and had several more problems other than the coils and the valve gaskets. The coils are relatively easy to replace yourself and can be done one at a time as they go bad but the valve gasket is a thing a dealer really should do. I have not had to replace all my coils so far however only 6 out of the 8. In addition to these issues leaky headlights and window regulators are also a common problem in these cars. I have had to replace one leaky headlight that fogs and one window regulator. I replaced the window regulator myself and it is possible to save costs but it is a job to do. Other than this the car is wonderful and I love it The car runs great once the coils are fixed and has plenty of power in the V8.
