Engine in or out?

Pull the engine and trans, clean everything with that biodegradable purple cleaner(use caution on exterior paint surfaces and aluminum), repaint the engine, suspension and engine compartment and reseal as much as you can while it's out. You can get catalyzing paint and spray it with an inexpensive Harbor Freight spray gun with amazing results.

Use synthetic disc brake grease on any parts that move wiggle or slide, especially on any bushings including shocks and front strut rods. It won't attack rubber or plastic, has a very high washout resistance and lasts for years. Try it on your rear suspension one time and you will never assemble a suspension again without it.
