looks good mate but jetwashing any engine is risky as hell with the amount of electrical sensors they have, but especialy a ECOTEC (EVERY COMPONENT ON THAT ENGINES CRAP LOL) My advice would be to spray your engine bays with autoglym vynil and rubber care.......spray it allover, agitate with paintbrushes if need be, then wipe off with drying towels, if you require a really shiney finish then spray allover again n leave for half an hour before soaking excess of with a sponge
