greasy old dirty a$$ 5.0 in my car . how should i clean it without messing anything up ?

 

just cover up all the electrical **** and spray some engine cleaner on there and pressure wash it off let it dry and hope it starts up. Also make sure the engine is cool not hot or you will crack the block(dont ask)

 

Get a zip lock bag and cover the distributor, then just spray some engine degreaser in there and rinse it off. Oh, and make sure she's cool like 67stangr said!!!
