Coolant in intake. ..
I know the coolant in intake topic has been beat to a pulp. .. but with an egr delete, would a bad head gasket actually fill up the intake with the truck sitting for a few months? It hydrolocked and it got parked. Pulled the intake manifold off now and most of the intake holes into the head are clear full of coolant. Would it run back up into the intake or could i have another problem like a cracked intake manifold?

You are going to have alot more issues than that, with parking a hydrolocked motor for months. With an EGR delete, really the only way for coolant to get in there is a bad gasket or cracked head. Either way, you will have to tear it down the same to check. Replace the gasket, get head studs and have the heads checked

Had plugs in oil side of cooler one had air chuck soap an water on coolant side no bubbles an 50 psi didn't lose pressure either. My first diesel engine I've been in to. The only one that has coolant in valve side is 2nd cylinder driver side. The o rings look junk . The fact it has no coolant in oil just oil in coolant has me messed up. I understand the hg problems but do not understand how coolant is in intake with j tube for egr . I do plan on redoing coolant filter an freeze plug the pump and rerouting coolant line .
