Is the front crank seal on a 05 5.7 hemi under pressure or part of the pressurized oil system also I’m pretty sure I already know the answer to the next part but would a leaky oil pan gasket and leaky valve covers cause low oil pressure as long as it was kept nearly full of oil constantly or replacing all of them cause the oil pressure to suddenly be so high that it is causing the motor to now burn oil. I was told by a shop that now that the oil leaks are all sealed up it is causing it to burn oil

what???? No the front crank and oil pan gasket are not under pressure unless your PCV has clogged or been plugged.

Not sure what would cause high oil press outside of using the wrong viscosity (the 5.7 loves 5w20) or a blockage. The gauge reading might change slightly if you replaced the pressure sensor, or the oil pump itself. However of all those posabilities only a blockage would cause it to suddenly burn oil.

A faulty bypass spring in the pump will cause pressure to run high as well, but definetely will not cause oil consumption or leak from the front seal, pan or valve covers
