Collapsed lifters

[Rsmith350]

L98, good oil pressure from the aftermarket gauge, entire head on passenger side has collapsed lifters. every single one of them. Drivers side looks just fine. WTF?

If they're full of oil, they're not gonna move.
Only an empty lifter will have noticable give when pushed down upon with a push rod.

Background.....the motor is a fresh re-build, hot tanked, bored...the whole enchilada. Has been running fine for the last month and then all of a sudden when started, had a bad clattering sound. Pulled valve cover to check for lash issues and found entire bank of lifters flat as a board. has to be some kind of restriction cause I'm getting 60 lbs. of pressure at idle and the other bank is fine. Gonna have to tear down and manually spin pump and see what the f*** is up.
