I have a quick question that i cant find an answer to. I have an 01 nissan altima with a head gasket that went out. I have a new head gasket and new head bolts but when i torque down the new bolts i have one that will not hold torque. If i replace that bolt do i need to loosen and re-torque all of them in sequence or can i just re-torque that one bolt? thanks for any help!
