Also replaced the 2 90 degree hose fittings with the aluminum


You have to determine where the leak is coming from to know what to repair if possible. Look on the side of the block at the frost plugs. Look at the hose fittings, just have to find the leak.

Just checked. The one freeze plug that is right next to the power steering is dry. It is wet underneath the freeze plug.

It isn't wet by the intake. And the water pump isn't wet either.


That looks like it is leaking from the bottom of the head where it meets the block, that would be a head gasket.


Sorry for your loss. These are crocking every 3-4 minutes. It will not be long, none will be able to be found, so you may want to put it in a back shed for 40 years.
