I bought a 91 Acura Integra a few moths ago and it was goin through alot of oil and smokeing outta exauset pipe. anyways i thought it was a blowin head gasket. I pulled my head off and i blew a pen sized chunk outta one of my vlaves. Im haveing my head rebuilt what else should i replace? where is the water pump? and should i be concerned about my bottom half? I have a book but really dont understand it. Im new to this stuff. you can reply on here, email me at cdahlin91@hotmail.com thanks for your time, Cameron
