real dirty engineeee

Consider using an All Purpose Cleaner (APC) such as Simply Green or Orange Lightning. I prefer the citrus cleaners. Do a search on the subject. Lots of past topics.
 
I like the citrus cleaners and have used Castrol's super degreaser a lot. Just used Citrus Engine Brite from Gunk, about $3 from AutoZone (it's a degreaser and detailer all in one); it did a fine job, but I keep on top of our engine bays, so ymmv.
 
Use a good degreaser that is not corrosive. Get some brushes to agitate stubborn areas. I prefer a water based dressing as opposed to petroleum based. Cover sensitive areas with plastic or foil. Find some patience. It is going to take some time and effort, but the end result should be rewarding.



Good info here plus search for threads as mentioned. http://autopia.org/kb/index.php?page=index_v2&id=30&c=21
 
·Remove any excess debris; leaves and etc form the hood, grille or air-vent openings.

·Spray all electrical connectors with WD40, which repels water.

·Use cling-film or Saran wrap elastic covers to cover any sensors, electrical black boxes, electrical devises that could cause an electrical short-circuits if subjected to water spray.

·This will not guarantee that you wont cause a problem when cleaning an engine bay but it will greatly reduce the risks.

·Start and run the engine to get it warm, not hot, this will enable the de-greaser to work more efficiently on a warm surface.

·Apply an engine de-greaser (Autoglym Engine Cleaner) by lightly spraying the lower parts of the engine first and then working upwards.

·Do not allow the de-greaser to dry or remain on painted surfaces, and be sure to dilute with water and dry with a cloth.

·For heavily soiled areas agitate with a nylon engine cleaning brush and a diluted general purpose cleaner (P21S® Total Auto Wash)

·When the grease and grime is dissolved and you're ready to remove it, spray with a light (garden type) pressure water hose.

·Use the blower side of a vacuum (avoid area that may be sensitive to a forced air flow) or allow the engine compartment to air dry and then thoroughly wipe down all accessible surfaces and then remove cling-film or aluminium foil.
