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

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.
