Gas in Oil???

[S13_E30]

I want to get your guys opinion on what might be causing there to be gas in my oil. From what I've read and previous experience of this happening to my 240. It can be a couple reasons, Bad o-rings , piston rings, the car running to rich (it shouldn't be though???) and I've heard something about maybe a bad fuel pump??? If you guys could pitch and help me buy giving your opinions I'd appreciate it.

not sure what you mean by o ring...

1. bad rings. un burned fuel is seeping past the rings ending up in the oil
2. running rich causing fuel to wash the cylinder walls which ruins rings eventually

if injectors are leaking badly you can hear the tss, tss, tss of unburn furl hitting the top of the hot pistons when you turn the car off.
