Williams engine headgasket help

[Olly1.216v]

In the process of doing my hg right now and torque them all to 30nm then was going to do 165 degress as i saw in another post. However the angle guage messed up. So in the correct order i then torqued to 1 to 10 to 50NM. I then in the correct order torque them to 80NM.

Does anyone know what NM is safe to go upto as i cant use angles but dont want to crack the block or snap a bolt. And i dont want to leave it half done.

you can mark the head with tipex and do a rough 165 degrees as torqueing isnt correct

ye but there strechted bolts so im worried if i un-do them and then do them up again if there going to clamp down correctly?

from memory we torqued them to 95nm on the old race engine

all 30nm in order (leave for 30min) recheck all to 30nm, then 95nm

something along those lines

Ok Fred thats great help thankyou very much. So 95Nm defantly wont crack the block or anything. Not the end of the world if i snap a bolt just dont want to crack the block

can't remember the exact figures, but 95nm rings a bell
