Got a friend who now has brown coolant and watery oil (if you know what I
mean) and am going to try and confirm a blown head gasket for her. I was
planning on taking off the valve cover and seeing if there's water being
pushed up through the oil passages. My question: is there anything else I
should check or look for? Unfourtanetly at my present location I dont have
access to any air tools and will be unable to safely jack it up as well.

Thanks in advance.
