Camshaft Bolt Torque To Yield?

[OutsideTheBox10]

Hello, I am just finishing up work on my 951 (camshaft reseal, some other misc stuff) and just noticed someone somewhere mentioned that the camshaft tower bolt is a torque to yield bolt? Is that true? I did replace the bolt but had to remove it during assembly to check that I placed a seal properly, so I technically torqued it twice?

That's crap... where did you read that?

The WSM doesn't mention it (only to replace with the later 12 point if the sprocket uses the older hex head bolt), and I assumed 65Nm was below the grade 10.9 bolts yield point.

There are no TTY bolts on any 944.
