What is everyones opinion on the best way to clean up the engine bay.
I have been told multilple times that diluted simple green and a power washer works wonders.

 

Yup. Just make sure to do it at a car wash or somewhere that the oily runoff won't contaminate anything.

Silicone Tire spray (the wet tire stuff in aerosol cans) is a great way to detail too, just spray and let it sit, makes the engine shine real nice.

 

^^what he said

 

My engine bay is soooooo dirty.

 

so what.... take a spray bottle of simple green and spray the crap outta the engine bay...and then hose it down with pressure washer?
Of course for my sri I cover the filter...
Anything else?

 

cover the intake, and try to use like compressor and hook it up with a air nozzle and purge out all the water if you can.

 

my method
1 go to car wash and use tire/engine spray
2 let sit while washing rest of car
3 rinse off when finished
4 dry
5 use armorall tire foam and let dry on its own
6 enjoy the pretty view
