~If your trucks using water, look at the inlet manifold or timing casingTiming casings the worst, a long hard job!
i hav put an front casing on and commpressor heads on and a water pump an an oil cooler rad weld seeems to cure it for a short periodā¦
d28ās do tend to start leaking from the front timing case, usually around the 700kish mark, pull the sump off and pressurise the cooling system and youāll see the water trickling round by the compressor. Bit of a p.i.t.a to change, enjoy 
EGR cooling modules have been known to pass a bit water too.
