problems aligning timing marks on 96 avenger 2.5
Hello to all. Here is my issue. The timing belt on my 96 Avenger jumped. The valves on the front (left) head were damaged. I replaced the head with a reconditioned one. On the right head, I removed it to replace the gasket, and the valve stem seals. All seemed to go well. I am now re-assembling the engine, and attempting to install the new timing belt. The problem is, I cannot get the timing mark on the rear (right) head into its proper position. I do not know how to proceed, and would appreciate advice. It is not that that the valves are pressing against the pistons. The cam is under load from valve springs, and won't stay in the position needed to line up the marks. So far, I have done everything by the book, but am now at a loss.
