Doesn't sound right to me either....

You don't think its a bad Rocker Arm, pivot ball, lock nut or an issue with a Rocker arm Stud ?
A too long or too short pushrod ?
Just my thoughts. .. somewhere on the Left bank you may want to check.

Right side is a problem too. #5 more than anything. Collapses over 2000 rpm when the oil temp comes up. Go back to idle, pumps back up. Changed out all of the lifters (cam and lifters looked good), the same problem. Oil pressure is well north of 70lbs cold (idle) and is at 50lbs at a hot idle (stock pump and spring) Checked valve springs...............they were new and good. Gotta pull it apart before something gets wrecked.
