So I am a 1 week old Jeep owner and developed a motor tick over the past few days. I found it today. Ran a compression check, all cyclinders were between 142-148psi. so I pulled the valve cover, when I got a look I saw my problem. #1 cyclinder had broken valve springs, 1st cyclinder back push rod was bent in the shape of a "V" the front push rod was M.I.A. so I pulled the head and took a look. Found the push rod in 2 halves in the lifter valley, and much to my suprise #1 lifter had popped out and was also laying in the lifter valley by cyclinder #2. Cyclinder walls were smooth as can be with absolutely no ring grooves. Pistons were very clean and nice and tight. Head goes to machine shop tomorrow to have the head resurfaced and a valve job done. order new lifters, pushrods, and a gasket set and gonna put her back together. Cam looked good, everything else looked good and rotated over smoothly.
