Hello, new to this forum & hoping someone could help. I have a 1989 Rapid with a problem with water coming out of overflow when engine is warm. there appears to be no pressure when rad cap is released & it is possible to blow down the overflow pipe when the cap is tightened-is this normal? I have replaced the head gasket & also fitted a new head, so I know this is not the problem. I have replaced the cap but not the expansion tank- is this a common prob with this engine? Could I fit a tank from a later Favorit which has no overflow pipe. Hope there is someone out there to give some constructive advice. Thanks, Chris
