Thank you, Racefan. I did look into that; was told my not a few GM techs that the intake manifold of the 5.3L is "dry"; no coolant paths up there.
Was told by Jack in here that it could be a head gasket that is not leaking coolant into the oil but into the combustion chamber. Now wondering if I am hurting my engine? I hate the use of coolant like that, but I dunno if a head job is worth it.
