actually, from all info I've learned from my oldschool pals the factory manual calls for honing the int shafdt bearings in these blocks. I'm told only the federal mogul bearings fit well out of the box, all the german made ones need honed. I just recently had a my machine shop do motor work on my 1.6 td and they used the federal moguls with no problem, engine makes great oil pressure, int shaft turns freely with no play etc.
