Odds are the egr failed and is trying to hydro your engine egr being turned off does not stop it from failing. Test the oil and remove the egr system completely. Slowly roll the engine over to free up the lock and go from there.

Would be easier to remove the fuel injectors and less likely to break them.

Yeah I have their stuff on my other truck! I was looking at it. I just want to block the coolant off and the intake manifold. I am fine leaving the egr there in place since it makes no real difference

Since it sounds like you have a failed cooler it would be best to remove it completely, or at least block the exhaust side as well.

The egr cooler is still under 100% of exhaust manifold pressure all the time and with swirl effect could still get heat in the cooler. Something as simple as a stainless block off plate between the cooler might be all thats needed. Since your cooler is already failed that is only going to bet worse and could cause bigger damage.
