crank case pressure

Update!! After using that coolant sealant truck ran fine for about 48k miles, now pushing coolant through the radiator tank exhaust valve, will only push coolant when idling at high RPM, I noticed that when I started a park regen and coolant was pushed so hard that it was falling on hood of truck parked next. Truck has now about 694k miles, like previously mentioned I have another engine of same specs, mechanic is asking 3500.00 labor for the swap, that engine has 725k miles, need an advice if I should go for engine swap or just fix the issue, or just use that sealant again and see if I can get another 50k.
