Although I have the I&amp;T manual and a full set of service manuals (from Jensales) I haven't been able to find a torque spec for the bolts in the rear main seal retainer (U-shaped gasket) or the timing gear cover.  

Maybe I'm looking in the wrong place...... or maybe there's a general number for this kind of thing that they assume people will know.....?

Thanks for any information on this.
