98 Chevy 1500

What will cause the oil pressure to blow the oil ring off the filter on a 5.0? Where could the pressure be building?

Too much oil most likely.

Oil level correct. Pressure is off the scale. Is there a bypass check valve on the 5.0 that will show pressure on tne guage but doesn't let it to the motor?

Yes there is a pressure relief valve which will be stuck if it is that high.
Question. Do you have engine oil cooler to the coolant radiator?
If so you could use it to possibly free it.
Did this all happen all of a sudden?

Happened suddenly and i pulled the mount plate down to check the pressure valve and it was functioning properly. Could it be a pump prob possibly?

You pulled down the mount plate??
The relief valve should be part of the oil pump unit as far as I remember.
If the relief valve is working then the oil pump can pump as much as it can and it will not overpressurize the system because the relief valve regulates it.
Take the pan off and pull the oil pump/relief valve unit off and check it out.

O.K. The valve I checked was the check valve. Will drop the pan and put in a new oil pump. Thanks will let you know.

A site to go to and look at how to pull the relief valve out.
