I have a 01 Dakota with less than 60,000 and both head gaskets are blown. I't took me awhile to figure it out. The truck would overheat, so I did all the common things, replace thermostat, radiator cap, and flush the system. I did these things one at a time. It would over heat after a few weeks. Then I realized that the system was getting pressurized and it was pushing the fluid out the overflow and causing it to over heat. I put only about 100 psi in the cylinders and I was getting bubbles in the system. The one thing I find a little strange is that I don't see any cross contamination. i.e. oil in radiator or radiator fluid in oil. I guess I really wont know until I tear it down, change gaskets and get the heads check for cracks or worpness. My question to you all has their been any word of these 4.7 blowing head gaskets? It is a new engine for Dodge.

 

I see this is dated Jan., but just a note.....2000 Dak. 4.7, my front differential blew at 88k, then the following morning after it was replaced with a used one the engine blew a rod. Nice luck eh? Sorry, it wasn't a blown gskt. but a brg.. New reman. 4.7 right now with 4k on it and the truck runs fine.......... and I also put it up for sale this week. I had enough of this toilet! Another story..........
