Message Disconnected and plugged the lines, so some water was still sitting in there, and then went for a short drive. Still plenty of smoke.

So the only other source has to be heads/gaskets.

I think next ill do a leakdown check on all cylinders at 100 psi when cold, then warm it up to smoking and do it again and see if there is anything different.

I think I'll also pull the exhaust and see if the downpipe on one side seems worse, from the tailpipe it seems even, but it might be getting mixed enough that I cannot tell a side that is better or worse.

I did pressurize the coolant system when hot and cold with a tester to see if I could tell where any leak would occur, I could not tell anything.
