Never meant to put the coolant system under that much pressure, put guage on truck, started truck and got busy for a min talking with my cousin and then jumped a mile when i heard the relief valve pop and seen the guage spiked just over 30 psi.

I after relieving pressure and watching it build again, i shut truck off with cooling system at 25psi, let it sit for a few min, saw small drop in pressure, fired truck up and saw a faint white puff of smoke. Thinking the 25psi pushed some coolant in to the bad cylinder.

Still waiting for oil sample, guessing if truck gets shut down with coolant system under pressure and it sits, if their is a leak their should be some sign of coolant in oil.
