1966 Galaxie 500 390 valve question
Im puzzled need a little help. I have a 1966 Ford Galaxie with a 390. I bought the car for 350.00 everything works and the car is in straight as an arrow with surface rust on the outside no rust holes and underneath the car has light surface rust my 2001 ford f350 has more rust. Anyways I have a clicking in the valve assembly. I took off the valve covers and one of the valve push rods is really loose. So since the car has sat for awhile I figured it was a stuck lifter. I pulled the manifold and replaced the lifters. Well guess what it didn't fix the problem. Next I thought stuck valve or bent pushrod well they all are fine. I laid a level on the valves to check if they were all level and flat with each other and they were.
So the only deduction I have left is a worn out cam lobe. If anyone knows or has another idea of what it could be please let me know. If it is a cam lobe how hard is it to replace the cam. The car runs like a top just has a clicking sound.
