So I bought my 93 Cruiser a little over a year ago and have been replacing, repairing and upgrading it non stop. Last month I blew the head gasket out and had that replaced and after still had cooling issues. could not find a leak for the life of me, after about 200 miles of driving id be down a gallon of coolant and immense pressure would build up in the system. This past week we finally ran pressure on the system and took a while and found a crack in the cover where the oil cooler sits. Take a look inside at the pics. Looks to me like the PO used hard water this whole time for about 200k miles on it and all this calcium was blocking it. Has anyone ran into this before or have any thoughts on it ?

I would guess that all is a result of a head gasket sealer not calcium from hard water.

Totally agree, he nailed it !
