now before I get flooded with the blown Head Gasket comments, ha ha let me give you a bit of a background and bring you up to speed

I don't know when this problem started. I don't know if there was a problem before I rebuilt the engine.

The short block is an original '74 engine, the top end now has '99 Suburban Vortec L31 cylinder heads.

I did not drive the truck often enough when it was all original top and bottom end ie long block to tell you if my truck was running out of coolant then, I wish I knew.

Well I've been adding water/coolant to it on a weekly basis seems like about a quart each Sunday night to last me through the week, but again I don't know if I would have had to do that before rebuilding the engine.

Also, important to note that we can not tell where the coolant is going,

there is nothing dripping below the truck
there is no white smoke coming out the tailpipe

The truck runs strong and does NOT overheat, well not until it runs completely out of coolant.
