I have pressured washed more motors than I can count and I have never had one single issue when doing so. All I do is cover the air filter if its an open element and that's about it. With EFI cars these days all the connections are secure enough to keep water out so you really don't have to cover anything up. I usually spray a degreaser over everything and go to work. I keep the pressure washer back at least a foot from the motor itself at 1600psi.
