So at 68k km's my left hand crankshaft has cracked !!
Head had been replaced about 1yr ago due to "the tick"..
Dealer is replacing both heads.. thankfully had about 2 weeka left on my warranty.. Dealer says it's the 1st they have heard of in Australia and I can only find 3 other references to it online on the US forums.. Hopefully not a sign of things to come with this motor..
Good thing I decided against a Sprintex until after my warranty had expired !
