I would check the oil relief assembly spring and plunger.
That is too much pressure. 60-70 psi is the norm.
If your oil leak is coming from the rear of the engine, check the PCV
system.
Do you have a PCV? 1275s need it.
One other thing, on assembly of the engine EXTRA care should have been
taken to make sure the "oil slinger/rear main seal" was perfectly
aligned or it will leak. (See leak free engine tech tips on PDLJMPR)
