1995 Mitsubishi Montero SR 6 Cyl 3.50L
engine oil looks like water got in it
how can i tell wich head gaskit is bad
Unless you see water marks on the block below the head, you won't know until you remove the head. It doesn't really matter which head it is, as you should replace both head gaskets if one is already bad. You won't be able to buy just one head gasket anyway.
