Do your Coolant temps and AIT's a favor

One thing I also did to reduce turbulence was to weld/smooth the two little EGR ports in the exhaust sleeve itself.

Obviously, its doing dick all by itself, but its another item that may just help keep that side of the engine cooler, and thus, take some load off the radiator.

But yes gas will still go around the sleeve, but there's yet to be a real solution to that problem being that the housing is AL and the sleeve is ferrous.
