I am repairing a 1990 245 with what I hope was only a blown head gasket.
While putting it back together I noticed one of the driver side freeze plugs is installed backwards. I said " What a fool!" After removing it and attempting to re install a new one I noticed the block has a lip that prevents installation in the normal manner, like the other freeze plugs. My 1992 is not like this, all plugs have the oval facing in. I said "What a fool!", and put the new one in just like the old one I removed . Anyone know why this is? There is not nearly the gripping surface on this plug vs the others.
