Ok so i just went out on a limb and bought an 02 gtp that has a cracked head they say but not sure anyways they wanted $1000 i offered $500 and they took it.. it starts and runs but not well at all they said it just died running down the road they pulled over and the front manifold was glowing which in past experience maybe cat clogged but anyways said it was blowing oil out the dip stick which while i have ran it very little it does have pressure in the crank case... so was wanting some of yalls input maybe heads gaskets just think its more due to pressure in crank case sorry so long thanks..
cracked head blown head gasket or just done??

If the head gasket is bad, you're going to have to take the top end off to fix it anyway, so I would take it down to the heads and see what's going on.
Is the Check engine light on? What codes is it showing?

Are you sure that's oil mixed in, not trans fluid? The trans cooler is inside the radiator and over time can crack and leak.

blocked PCV can cause excessive pressure is the motor.
A glowing manifold is likely a block in the exhaust system, so clogged cat is a very good chance.
Id so some well needed maintence to the motor first.
Like a full service:
Plugs
Wires
Lower Intake manifold gaskets and valve cover gaskets
PCV
Coolant flush
Oil change
Blowing a head gasket is very rare for these motors.

injector is a problem. pull the injector connector off and check resistance of the injector. they should all be between 14 and 16 ohms. I believe the spec is 15.6 ohms.
if its open its shorted internally and needs to be replaced. I might have one or injector that should be working that you can have for the cost of shipping if you need them. someone else closer to you might have some you can buy. yards might have them as well. new is overpriced.

PCV could be plugged/ welded on the bottom of the supercharger if the car/ supercharger were ever modded.

You can get a new engine, or get a new block if your top end is good.

missing electrodes is better than smashed ones...
You can burn the elctrodes off due to limp timing and beating on it. (done it a few times before on the turbo cars, no issues).
You are basically going to either borescope it and see if the pistons still exist, or just put new plugs in and figure out why you burned the old ones out.
