Engine mount on an AUM. 18mm head M12 bolt. Go to undo it and stupidly tight to undo. Great we're into trouble here. Undo with a big bar and thread full of aluminum.
Why on earth did VW use M12 Steel bolts going vertically into an ALUMINUM block to hold the engine. Vertically.....
Yes bolts will be replaced as one use but how stupid is that?
M16 thread into stainless inserts being put back.........
