Z28 chevy camaro help please!?

It is a strong possibility that the fuel injectors are leaking. Do a fuel pressure test to check the fuel pump, fuel filter, fuel pressure regulator and fuel injectors.

Bad oil rings (on your pistons if you don't know). It's going to cost a decent amount of money to fix to tell you the truth. It doesn't sound like you're going to be able to do it yourself so I'm not sure how you're going to want to proceed. On an aging car with some wear it might be beneficial to actually replace all the crank components (besides the crank and rods; just check the crank and rods to make sure they're not warped) and hone the cylinders. But again...not cheap, not cheap at all. You could always swap in a junkyard engine or rebuilt engine but again not cheap. It's not THAT (Extremely! You're gonna die!) dangerous to have gas in the oil but if you have emissions in your state it probably won't pass; it's not completely safe either because the crank is pressured, but not really to the extent where it's going to cause an explosion because of heat (because slipping oil rings work both ways, they kick gas into the crankcase and kick the gas/oil combo back into combustion).

It sounds more complicated than it actually is theoretically, but the repair is fairly involved even when you know what you're doing. Some mechanics will tell you to replace the pistons, rings, and rod bearings (rods are probably okay), others will just replace the oil rings; if you plan on keeping the car for a while listen to the first mechanic.

My opinion. Of course it would be better/cheaper if you could do it yourself.

so if the radiator hose is bulging, the thermostat is stuck closed and not letting the water into the engine.

Purge valve may be defective and dumping raw gas into the intake.
