When
you add torque to those bolts, the bolts closest to them will go under torque.
So go
through the whole torque sequence several times if at all possible. This has been
the case on every engine I have built.
I don't
havea Mazda Manual, but generally
in a case like this there are 2 ways to tighten the bolts correctly:
a) Tighten
2 opposite bolts until seated - then torque each to spec. All other bolts are
tigthtened spreading out from the 2 torqued:
e.g.
Torque the 2 big bolts then: 1st bolt to left of one big b. - 1st
bolt to the left of the other big b. - 1st bolt to the right of the one
big b. - 1st bolt to the right of the other big b. - 2nd bolt to the
left...... you get the idea.
This
way you have the pieces flat together on a "centerline" and
"lay" the rest down on each side of this centerline - spreading it
out so that no "wrinkles" are created....
b) A
stepped sequence is shown in a manual: mostly in cross pattern and something
like 10 lb/18lb/26lb
Thomas;
I
understand the niceties of torque sequence; but it would seem that is all out
the window when the engine has been run about 6 hours, many cycles to full
power, and a dozen or more temperature cycles to 200-210 F; all with the two
large bolts loose. As far as I know nothing untoward has happened, but
how can I be sure?

Al,
didn't
intend to step on your engineering prowess, you are waaaay ahead of me in that
department!
Hey; Thomas;
You weren’t stepping on my prowess
(assuming I had some) at all. The info you gave is right on and your
response appreciated.
