Collapsed Lifter Jeep 4.0 at Darlene Daniel blog

Collapsed Lifter Jeep 4.0. Rattles pretty intense at idle, sounds fine when reved up, typical jeep 4.0. If the ticking only occurs at first start after sitting for a while like. I know it could be a number of things but i feel like it originates in the valvetrain. The engine uses no oil, has 45 psi at idle, hot and runs good except for the one bad lifter. You have to pull the head to replace lifters in the 4.0. He did have 2 suggestions: I have a 1998 zj with 4.0 with a clicking lifter and taking the valve cover off will tell you if the lifter is collapsed or seized. I've seen quite a bit of sticky lifters and collapsed lifters on a 4.0. I have good compression on all cylinders. Has anyone had a lifter get worse. When the lifter is sitting on the base of the cam the rocker above a collapsed lifter can be rocked back a quarter of an inch or so. Remove the belt, start it up and see if the noises are still there. I have a few ideas to solve this problem. 1) throughly clean (and if i choose, disassemble) each lifter and ensure proper operation.
