What could make my engine burst seals?

If its a factory one, dont trust it.
What oil do you use?

As for the high oil pressure, the only thing I can think of is a faulty pressure relief valve in the oil pump. Either the spring is of a way high spring rate, or there's something keeping the valve seated, IE: gunk, dirt.

I would expect the pressure relief valve to show its effects at startup where the pressure is more likely to exceed its relief value, rather than once the oil has warmed. The pressure should drop naturally as the oil temp goes up and the viscosity decreases.
If it does not go down when fully warm, the pressure relief isnt working. For ease of your repair, I would hope its a bad guage read (stuck reading cold pumps pressure? A friends loyale wagon did this.)
The dash gauge, like all dash gauges can be somewhat inaccurate. The sender unit can give some truly odd values, especially if damaged.
Mine shows 75 PSI at idle while cold. The first time I saw this reading (the car was new to me) I cleaned and reinstalled the pressure relief valve, but it made no difference.

Are you sure you're using the correct oil viscosity?
Most likely, id say your pressure sender is bung, you should temporarily install a mechanical gauge and see how that reads.
