I have a 1066 with about 6000 hrs. that has developed a tick at top rear of engine that has been getting progressively worse over the past few weeks. Removed the valve cover today and noticed that the top end of a few of the push rods seem to be worn or collapsed to the point that the adjustment screw fits very loosely inside and there is excessive rocker to valve clearance. Also started engine with valve cover off and at low idle noticed oil pumping out from rear rocker only. Noticed on inside of valve cover that area above this rocker and the very front one were wet with oil and clean while the ones in the middle were not. My question is does that sound normal. I am thinking about replacing all the push rods to buy a little time to get the crops in this spring as we had planned to have an in frame overhaul done this summer anyway. I am not a mechanic but thought I might attempt this myself. Any advise would be appreciated especially in regards to setting valve clearances. Thanks Rich.
