Inspecting The Pushrods
Clean the pushrods thoroughly.
Roll each pushrod on a flat surface. A bent pushrod will make itself known in short order. Replace bent pushrods. They cannot be straightened.
Check the cup and ball ends of each rod for damage, flat spots, wear, cracks, etc. Replace any pushrods showing signs of damage.
