I finally had some time to go pick up an iron block 5.3 that was given to me.

I also have a deal in the works for a complete aluminum block 5.3 engine, accy's, harness, etc. coming soon from one of our members here.

It was swapped at 60k for a suspected cracked head. It was slowly loosing coolant. Not too uncommon for the early 5.3's. My cost on a new casting is right under $100. If I see no signs of burning coolant when I pop the heads I will send them off to check for cracks.

Sure enough the head was cracked on the #6 cylinder.

I have also picked up a 6k mile 5.3 from MalibuKasey in trade for my 355.

Doober, chances are it's the head. I have seen many cracked heads....especially the early Gen III 5.3's, but no blown head gaskets. They will most often crack in the ports. But they CAN also crack outside of the port area leaking coolant right onto the lifters causing the lifters to tick well before you start making a milkshake.
