2006 Dodge grand caravan SXT w/145K 3.8L V6 head gasket blown. Do Fusion Sealers, Titan sealers, or Thermagasket sealers work and which is best
The best way to go at it would be to have the head gasket replaced.
I use sodium silicate to seal breached head gaskets.
You can order a 12 oz bottle of the stuff from a local pharmacy for about $25.00.
