There is no way to know but that sounds really bad. I would probably pull the heads to see what is going on.

If coolant is coming out the tailpipe (Not just regular water condensation) your LS Based engine can have a blown head gasket(heads must be resurfaced and valve guides checked) or a cracked cylinder sleeve or the block itself. The LS engines are great little engines but they will not standup well to overheating. I have seen 5.3l and 6.0l LS with cracked pistons, sleeves just from being overheated. No high RPM are racing. I'm talking 2500 and 3500 work trucks. Tear it alerts and see what's up
