[Vwdiesel] [Audi-VW-Diesels] Head Bolts and more

[Dave Cook]

How are the bearings replaced then?  Are they similar to the bearings on the crank/rods?  (Half shells?)  The bentley didn't have much on them other than to say they don't wear much, if they do replace the block, but take the shaft out and make sure the surfaces are nice and clean.
