Ah ok. But what bolts on the engine are TTY then? The service manual doesn't say to replace the head bolts but it says to replace the ring gear bolts.
BTW, what exactly does torque to yield mean? Is that at the limit of a bolt's stretch? I thought torquing bolts is meant to prevent a bolt going near it's tensile failure point?
Anyway, going to bed now, so I can't reply at this time
Thanks
