The history of the Rabbit diesel is full of problems ---Leaking Headgasket Warped Heads Cracked Heads etc
its my judgment that Thermal expansion and   contraction is at the root. Poor workmanship may be a problem in assembly as well.WE shall overcome ----
Aluminium expands at much greater rate than steel and cast Iron.Test ? bolt two pieces of metal  say 2 x 6 straps together at the ends and heat ---and hang on to your socks.     Hagar.

PS: yes alloys do vary in expansion , none that I heard of comes close to Iron. Cracked head # 1 62000 Km.    # 2  95000 Km. from factory.
Pretty sure VW Canada said max crack  0.3mm--after that the smelter.
