Powerwashing my motor?
I don't know about you guys, but I'd love to get the initial larger amounts of build up/AZ dirt out of my engine compartment real quick haha. Is it safe to powerwash the motor especially since I still have the stock airbox/snorkel? On my 01 f150 with the 5.4, when I washed it I know it ran terrible afterwards because I guess the water gets in the plug boots or coils or somethin and messes with them for a little bit, which it did and then stopped after driving for a while. Somebody told me the best way to do it is to cool down your motor, then start it up again while washing the motor. Any suggestions or is this a no-no as a whole?
