What do u mean a plug in the back of the block? If that's a sensor it can't be the issue because iam not getting oil to the top of the engine. I made a post on th issue in the ls1 internals forum
No there is a plug in the back of the block. People call it the barbell.

Time to pull the motor... I've had collapsed lifters before, but never went to "0" oil pressure. Sure it's not a spun bearing noise, plus the lifters rattling ? Either way, you're pulling the heads to get to the lifters.
