1hz crankshaft flex

This is a follow up to a previous post that I submitted regarding my 105 series 1hz with a inconsistent ticking noise coming from the motor. I thought that i was finally going to get the crank replaced after 2 1/2 months of disputes with my local dealer and Toyota Australia. But no I had 2 Toyota techs from melbourne come down and confirm the noise to be Crankshaft flex which was the original diagnosis from my dealer, Any way at the end of the day Toyota acknowledge this problem and say. And I qoute "There is no concern that a failure would occur from the crankshaft. Replacement of parts is not expected to eliminate the noise". My dealer told me that toyota have changed a lot of cranks and the noise just comes back after 10 or 20 000 kms from what I can understand it is the actual block that is out of wack which causes the crank to flex in turn making this noise. Lovely on Toyota's behalf its an absolute disgrace.
