No, I was looking around for several other missing tq values. I pulled off my gearbox cover and I was wanting that values for all those smaller bolts, but couldnt find them.

"In taking off my diff cover I noticed they use red locktite!"

Big Turbo:
Recently swapped in a Wavetrac so been there and seen that. The red I saw I believed to be Loctite 515 or 518 forming the seal between the two aluminum flanges. Perhaps the factory used red on the case fasteners too; but I did not notice it. I used 515 to re-make the seal between the aluminum flange faces.

Anyone figure out the diff cover bolting torques? I'm assuming they are similar to the carrier bearing cover torques, 20NM +45deg as they are similar bolting material and bolt design albeit different length.

For replacement diff to cromwheel
I used what I found on a PDF for a Vauxhall Quaife install, 80 NM with red loctite, hope this helps future DIYer
