Ok, so I bought this truck two weeks ago, and the only code I get is for the CHT sensor. After looking at where it is, I get the feeling I am in the market for an intake manifold gasket set, some fuel injector gaskets / o rings, possibly an EGR gasket, a new thermostat sounds like a good idea now too. Is there anything else I might need when doing this job? I am not familiar with these motors at all, as my last truck was an I6-300.

Are there any suprises that I might encounter? I'd like to have everything on hand before I start this little job. Thanks!
