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?  |

Turned on a lathe with a TNMG insert.
 so.. you want to machine. Titanium Nitride coated by vapour deposition. tnmg is the code descriptor of one of thousands of configurations available. the catalogs are great tomes too large to print these days so we download pdfs. //http://www.sandvik.coromant.com// |
