Spent some time on my motor today. Before tearing it apart double checked pre -load and everything is good. All the valve tips look good and nothing else looks out of the ordinary. The lifter was f^%c&^D and wouldn't come out, luckily it was cyl. #7 so I could reach in the cavity on the block and push it in and pull it out through the cavity. Bad news is the roller split and the bearings went south so now I'm pulling the oil pan to clean it out and will be doing the pump AGAIN. Once I pull the heads apart I'm going to test the spring pressure to see if they're fatigued because I'm not seeing anything else.
Any thoughts?
