I don't like on the 4.6 2003+ how the oil splashed all over the steering rack fittings. Makes a huge mess. and surprisingly not the easiest to get out either. Especially if someone has "massaged" the lines.
The old 5.0 is so easy.
The blue Town Car rolled 228K. It's had new motor mounts installed and makes the car so much better to drive. New airbox (better sealing design) from the junkyard. 70MM tb off a Lincoln Aviator. New Motorcraft water pump, thermostat, belt tensioner assy, belt, and idler. Junkyard 50K 4.6 alternator (the old one's bearing was starting to make noise after 227K!). New drain plug from Ford in oil pan since some dumbass german torqued and stripped the threads on the bolt. New power seat motor so now I can sit where I like, not behind the B pillar. This car runs phenomenly. Next year I want to replace the exhaust manifolds, dipstick tube (has a rot hole) and the trans dipstick tube (welded on??). Love driving this car.
Still need to address the mushy brakes.
