anything at all to prolong my 147K mile motor???
The tranny needs to kept clean more than other parts, and the power steering pump is cranky if dirty too.
The engine uses the oil in the injectors, so keep that clean, and change it regularly - do not use an oil that is not compliant with the specs in your handbook. Most people use Rotella, which seems ok. ford recommend the Motorcraft oil they sell. Mobil make a few good ones too.
Get a new air intake system, to open up the air going in, and a larger downpipe, at least to let it out again.
That is maybe enough to keep you busy for a while.
