So the wife calls me and tells me her check engine light is on in the Durango but it is still running fine. Pull the codes and it is for the cam position sensor. Grab a sensor and change it out. As I am in there I notice that the coolant is pretty dark. Check the oil and it is not even registering.

I am assuming there is a head gasket leak. Truck has 78k on it and has been maintained by me all its life with no prior issues. Did some google searches and didn't really come up with stock hemis. Has there been any issues with cylinder head castings or even factory gaskets?

I am looking for some advice on what to change while I am in there (this will be my first time tearing into a 3rd Gen Hemi).
Should I buy new cylinder heads or just get them checked? Head studs, valve springs etc? We are planning on keeping the Durango forever and I want a bullet proof package.

Any advice would be appreciated.

Thanks,

Josh
