Help: fuel in oil!!!

OK I have more fuel in the oil pan than oil right now. Where do I start? Toasted o-ring? Bad injector? etc etc. Just looking for some opinions on what to start looking into. Looks like a 12v swap may be in the near future.....

long shot but: is it possible its the fuel pump? If the diaphram cracked wouldnt it be possible is allowing fuel down into the crankcase? I just cant see it being an injector as it was running just fine until i went to start it on sunday.....

I have access to a super cheap NBS 7.3 motor, but I has a bend rocker arm, needs an oil pan and some small other things. Isnt virtually everything internally compatible between the two? same blocks right? IIRC the only differences are rods, turbo/piping, I/C, and HPOP right?

You could have a bad injector cup. If you are getting that much fuel in your oil. Or you have a a crack in the cylinder head and it is leaking fuel into the engine. Or you have bad O-ring on one of your injectors.

so if it is an injector problem, wouldnt I still have to have a problem with a piston/o-ring? Otherwise how would fuel be reaching the crank case? Is one problem more likely than another? thanks

dumb question but what exactly are the injector "cups". I have done my own injectors a few times already so is this something I would be able to do myself?

If I remember correctly. When you pull out the injector look down into the hole that the injector just came out of. You will see it. Its thin and hold the injector. Should have a small hole at the very bottom of it. I don't know if you can get them out with out damageing them Some one will chime in in a few.
