I have an 86 Mercruiser 470 and found water in the engine oil while changing it. I have noticed some anti freeze loss. I know that could be either a head gasket or a cracked head. My question is could I use some Bars stop leak for a temporary fix? I know it is a small system so I was wondering if maybe a half a bottle would help or hurt it?
