[Vwdiesel] TDI blunder

[James Hansen]

You haven't exceeded anything yet. Not the rated torque the torque to yield
fastener starts to yield at, or the compression thickness of the gasket.
(which should be the metal sandwich one, right?) You haven't done the final
1/4 turns yet, so are well under that amount of squish.
Back the fasters off and retorque to your first increment, ONE AT A TIME,
until they are all back at the start, continue as if nothing happened.
Sweat not, panic not, trust the force....

Well, I stumbled across enough motivation to stick the head on the TDI
tonight.  So, I whipped out the head, gasket, and sawed the heads off
two old bolts to use for guides.  Stacked it all on the short block and
started tightening.  Put it to fourty, then as I was taking it to sixty,
one word crossed my stream of unrelated counsciousness:  Newton-meters.
Needless to say, I was torquing it to foot-lbs.

What I should have done:  30 ft-lbs, 44 ft-lbs, 90º, 90º.  What I did:
40 ft-lbs, 60 ft-lbs, curse.  I'm thinking that I wll have to remove the
(stretch) bolts and replace with new since it's overtorqued to an
indeterminate degree.  My immediate question is should I replace the
head gasket as well, or just replace the head bolts one by one and hope
for the best.  Seems like I remember the Raceware bolts being installed
one by one without replacing the head gasket, but then again, they're
done all at once, not in several successive torque steps, as I recall.

That's what I get for using an American torque wrench with ft-lbs in the
big obvious numbers and a Geman car with N-m listed first.  That, and
not paying attention....

So, anyone with some Raceware experience and a lucky guess got some
advice?
