The motor for some reason is pushing oil out of the pan up and out the dip stick. Really stumped i recently did a motor swap and used the stock motor with all stock parts oil pump included. I think i might have something to do with the pressure in the crank case maybe not sure really need help please.

Is the pcv valve in use? are the valve cover vents in good working order?
Is the engine overfilled on oil? Is the engine sealing up well or does it use oil?
Sometimes TBI engines have a bad habit of forming crud buildup in the vacuum ports and if the pcv valve isn`t getting enough vacuum it`ll cause the issue your having. If the engine has excessive blowby from poor sealing rings it can cause the same issue also.

I once bought a 4.3 Blazer that would blow the valve cover oil fill plug off. It was a carbon plugged passageway under the injector, in the egr system

The motor will aslo die after running for a couple of miles wonder if it has anything to do with the oil problem

I wonder if dead cylinders could possible cause high oil pressure.

No, it won't.

If this is a high or unknown mileage/condition engine, and the PCV valve and plumbing is correct, it could be a case of it simply being worn internally enough that there's excessive blowby- which can cause oil to come out the dipstick tube.

Regardless, start by draining the oil from the pan into a clean receptacle (so you can reuse it) and measure what you put back in so it's to spec- unless you already know the oil level is correct from a recent oil change or you know the dipstick is reading correctly. Count the filter as a quart- it isn't, but w/what's left inside the engine plus what's in the filter, a quart is about right.

You can see excessive blowby w/your eyes if you remove the PCV valve w/the engine fully warmed up and watch/feel for pressure at the valve cover grommet.

You should also pull the plugs to see if they're oil fouled and check the exhaust for smoking while accelerating, coasting down in gear and at cold start-up.

A compression test or leakdown test can also show you if there's excessive blowby, as can a vacuum gauge.
