All,

I am in the middle of some maintenance following the initial 500 mile break-in
period.
Since I had the rocker pedestal off to torque the head down, I took must
trusty dial indicator and measured the cam lobe lifts.
The Bentley manual says this should be .26 (max).  I am thrilled to report
mine at:

1 = .256
2 = .256
3 = .256
4 = .258
5 = .257
6 = .256
7 = .256
8 = .258

A maximum deviation of .002 between them, and .004 from the .26 max given in
the manual.
This looks good to me, even though I did not take measurements at rebuild.

Anyone think otherwise?




Cheers,
