well on second thought you could be right

And I've seen worse.

That'* chugging quite the lot of coolant

If it was cracks in the EM, wouldn't exhaust come out like that, also? Bill, did yours leak exhaust like that?

That'* steam. My LIM gaskets were good, and exhaust is invisible.

Could you smell, hear, or feel it?

Nope. But I know right where to look now. You do to. Just look at those pics I linked to in the topic. With an inspection mirror and a flashlight, you should be able to see most of those cracks. OEM exhaust manifold gaskets would have prevented perhaps SOME of them.

with that second video you proved yourself wrong, when you rev the engine the coolant doesnt pressureize, it justy moves faster.. if it was a head gasket, when you rev it wouldnt change that much because it would effectively be within the same general pressure, but would blow more from the exhaust leaks by pressurizing the exhaust more

My 95 had crazy cracks all over the place when I got it. I was hoping for a bad exhaust gasket between FEM and REM'* but no luck. I felt mine and could hear as well. But it wasn't horribly loud.

I would also say he'* got intake manifold problems as well..see it a lot at work ( Pontiac dealer)
