Cleaning engine bay
I was wondering what's the best way to clean my engine bay. I want it to look really nice and new like fresh out the factory! Let me know any suggestions, what to do and not to do.

Simple green works, and a good pressure washer.
Cover the alternator and the distributor so they don't get drenched. A rag would work fine. I wouldn't worry about anything else I've never seen a Subaru engine have any problems from washing the engine. You can pressure wash it with the engine on or off I've never seen it make a difference in newer cars.
If you want to be safe, you can use an air compressor to dry off any electrical contacts and sensors you see. Or just wait till its dry to start up the car.

leave the bay dry, spray some Adam's All Purpose Cleaner, agitate the solution with fine brush, then rinse without pressure. Just be careful with eletrical and your are fine. If you are worried, cover alternator and battery and you should be good to go.... Man, I need to clean my engine by too...

haha yeah, after you wash, spray with pam! but that would probably burn off by the time you need to wash again, unless you do it everyday or before RallyX
