exhaust torque settings

[daveac]

Hi,

Can't find this in the manual so just checking - are there any particular torque settings for the exhaust manifold bolts or the lambda boss?

Thanks

Dave

Llambda boss will be welded into the exhaust but for the sensor:

4. Install sensors with new gasket if supplied and torque to specs as below:

M18 sensors - Install finger tight then 1/2-3/4 turn with spanner / O2 sensor socket 26-33ft. lbs.

M12 sensors - Install finger tight then 3/4 - 1 turn with spanner / O2 sensor socket 13.2 -17ft. lbs.

As for the exhaust manifold i guess you mean where it joins the cylinderhead    

If so, Not sure if the sigma is on studs or bolts but on a silver top zetec the studs are torqued to 7 lbs/ft and then the nuts 12 lbs/ft    (Ref' from Haynes)

Just tightened up really, no need to go beserk
