[QUOTE=Shawn T. W.;2253611]Why, how would it hurt your engine?QUOTE]
i did this to my engine,had air cleaner off and power washed engine so i plugged all holes that could let water in.than i started engine and puled car in garage and let it run for 2 min till my dad asked about huge puddle of oil on floor.shut the car off and looked and had valve cover gasket leaking at front left corner.so yeah it may not hurt engine but will make mess for sure.just my own expirience
