Nissanman Posted February 17, 2008 Share #2 Posted February 17, 2008 I assume the coolant is not exiting from inlet or exhaust passages?There is a welch[freeze] plug at the rear of the alloy head that could be the culprit, although they are normally all replaced when a head is reconditioned:disappoin.The plug may have a hole rusted in it and it has started leaking under pressure:nervous: Link to comment Share on other sites More sharing options...
