Question AU1 and AU2 I6 head bolts

Has anyone heard of problems with the head bolts on these cars. Apparently Ford have had a dodgy batch of head bolts (very soft) and they have been breaking. My mate spoke to a dealer and he said that they have been doing 5 to 10 falcons a week. Is there any truth in this????????

Havn't heard that one but for the earlier models my service guy said they use the AU bolts when replacing head gaskets, they don't stretch as much as the earlier ones do

If anyone has the inside goss on these let us know - I want to get my head gasket done soon

Cheers

I thought there were the days of EF's when they had stretched/snapped headbolts.

Don't tell me Ford still haven't got the problem sorted. :dead: :dead:

Needless to say when they pulled my bolts out of the head on my car during the head gasket change the bolts were in relatively good condition and not snapped.

You didn't use them again did you EF_Falcon_Guy?

They are meant to be use once and throw away. This is becuase they are actually meant to stretch or yield on installation to maintain clamping force. Not for reuse!

I thought I had read on another board that the AU bolts were the ones to use for anything from EA-on. Haven't heard of a problem with them.

I don't know if its the same for the i6 bolts, but the 5.0 also uses TTY bolts, they can be torqued a max of 3 times.
