    Had water in my oil and suspect a head gasket issue. The question I have is where is the powerhead gasket or is it the same as the head gasket? I am also planning on replacing the exhaust gasket to be on the safe side. I have heard the powerhead gasket can go bad also and cause water in oil. Thanks in advance!
