2012 6.7 Pressurizing Coolant Bottle

[Jeremyn21]

I have a 2012 ram 2500 with and hs tuner on it about a month ago it started over heating and pushing pressure into coolant bottle. It doesnt happen all the time its random. I replaced the t stat and flushed the rad. Could It be the head gasket? I never seen one go and be fine sometimes.

Gasket is probably blown in between the multi layer and compression is escaping under boost.

The MLS gaskets are able to seal up after a blow or leak. Not all the way of course though.

I meant to say combustion is escaping, but I would bet that the headgasket is blown.

That's what I was afraid of thanks for the replies.

Definitely head gasket. Blew 2 on my 2010 with the H&S tuner before finding a combination that works.

Well I guess it's time to sell some 12v parts for the toy and fix the daily driver any suggestions on good turbo's for the 4th gen. If I have to tear down the engine I'm guessing injectors head studs cp3 and turbo are in order.
