The oversize pushrods have been a months long subject of discussion and disagreement, as to the relevance of them and their relationship to the continual unsettling of the intake manifold. The mechanical interference appears aggressive. Some of the pushrods exhibit multiple contact areas.
The pushrods are tapered, the largest diameter is the center of the pushrod. That's a lot of lateral loading and unloading each time a rod makes contact. Math puts the cycling into the many thousands of times in a very short period.
These pushrods are the originals. They have 700+ miles on them.
These photos are of the 2nd set of pushrods that were installed in an attempt to reduce the amount of oil being transmitted to the valve train. They have about 135 miles on them.
