Just helped remove a 1.7 today and this is what came out of it.
There were probably 4 push rods that had varying amounts of this wear. I could make a guess at what caused it, but this end was seated in the lifter. Just curious.... anyone want to guess?  |

Nope, retaining wire got it.. It was probably inverted at some point by someone who didn't care, or didn't know any better.
The pushrod rotates as it reciprocates, which is what leads to this perfectly machined surface. |
