Iam really sorry I posted this now...No positive energy hereGB
The AHU/1Z uses the same rods as the AAZ. My searching during my planning period found about a half dozen windowed AAZ/AHU/1Z engines all of which seemed to have oil in them at the time given the mess that resulted.

I saw enough broken rods on TDIClub that I decided to upgrade when I built my engine. If you are doing a performance build you probably are going to upgrade the rod bolts plus get your factory rods resized by a machine shop, so why not spend a little more and upgrade them. The cost of rebuilding an engine that has experienced a rod failure is waaaay more than the incremental cost for upgraded rods.I went with the Integrated Engineering Tuscan rods:http://www.performancebyie.com/integrated-engineering-tuscan-144x26mm-1-9l-tdi-rodsThey fit the AHU/1Z perfectly including clearing the intermediate shaft oil pump drive gear which is a problem with some of the aftermarket rods out there.
