Default head torque spec
What is the torque spec for the 6 head bolts on my 08 ec300? I'm assuming incrementally tightening in a star pattern?

Here ya go
Place the cylinder head and tighten the screws in diagonal
pairs. Use thread lock.
Tightening torque: 25 Nm
- Check that the support surface of the thermostat cover is
perfectly clean.
- Fit the thermostat cover with a new gasket and tighten the
screws -1-. Use thread lock.
Tightening torque: 10 Nm

BTW 25nm roughly converts to 18.4 FT/lb

Sorry to be bringing this back up but would these settings be the same as the 2002 ec300? Also is it better to build the o rings for the head in dry or coated with grease or three bond sealer? Thanks.
