this is a VERY "mission-critical" bolt and not one ya want to come loose or let go at/near redline. The results are engine-fatal. Fortunately for him his question was already answered correctly at another forum.

"best guesses, beliefs/opinions and other unqualified answers" should NEVER be proffered on a question like this. Some day someone will take it as the gospel-truth and I doubt the person answering will accept responsibility/culpability for the answer they offered by buying this member a new engine if he uses the advice given.

If ya don't know then the best you can do for this person is say NOTHING!

the picture I have of the timing belt change I did. Since it says in the diagram.

And it might have helped him to find the answer if he spelt camshaft right. Im not sure it if was just a mistake this time or if he does spell it like that all the time.

but this particular bolt has plagued me for years so I use my own home-brew method which I won't even mention here out of fear it would meet with disasterous results if someone else tried it.

The book that was taken from is likely one of the early Haynes/Chilton repair manuals.

The Bentley spec is as follows:

This is a true "stretch-bolt" so a new (not re-used) bolt must be used and tightened to 22ft lbs then an additional 1/2 turn (180 degrees).
