Remove the valve covers. Inspect each rocker arm for wear, cracks or other damage, check the rocker arm abd dykcrum for wear, replace with new ones, they can"t be adjusted.

The rockers on the 2.5 motor are hydraulic lifters.They cant be adjusted.If there is a noisy lifter it may be a different problem.What's happening?Hope this helps

yeah it needs a new cylinder I see this all the time. The valve stem guide in the head drops and sticks the valve open the rocker and cam lose tension and thats why the rocker keeps breaking. Take the valve cover off the head that your have problems with. remove the rocker put a socket over the valve spring. gently tap the spring down without loosening the keepers. You will notice that the valve will not return to the closed position. I garuntee this is the problem u r have I hate to give u the bad news.
