hi guys and gals
I have been busy doing the head gaskets on my 1996 4.6 hse
now the lr manual says torque settings are 20nm then 90 degrees then a further 90 degrees, {in the correct sequence of course } im using new bolts elring gaskets and the heads have been pressure tested and skimmed.
however after tightening the bolts to 20 nm and then 90 degrees it felt really tight. no way am I going to get another 90 degrees out of them, so I decided to measure how tight they were using the torque wrench. the bolts would not move until 145 nm was reached but according to lr they still need a further 90 degrees. what are your thoughts on this surely 95 to 100 nm is plenty tight enough. sorry for being so long winded didn't have this problem with my classic v8. as a ps I broke 5 sockets and rounded off an impact socket removing the bolts and one of them was a snapon socket.
