6 lb/ft is about it for soft gaskets. Anything more than that and you'll have problems.

FYI: The newer/current aircooled 911 rocker gaskets are not "soft"... I torque mine to 18 lb/ft as recommended by Peter Z & I've had no leaks from this area in nearly 15 years!

"Regarding torque specs, I'll say this one more time, with a couple of qualifiers. For 911s built through the '89 3.2 litre Carerra, that use 11-hole, aluminium lower covers, and use-once super-thin greenish blue gaskets, or green gaskets with a silicone bead, the torque spec for the 8mm Nylok nuts, used with proper German aluminium sealing washers, is 18 lb/ft.

It has nothing to do with heat cycles, or anything else. My shop buttoned up thousands of 911s using 18 lb/ft, many we didn't see until the next 15K service was due (many of our customers would have the in-between service done at an oil change only facility, or they would do it themselves). NONE had to return for follow-up tightening, NONE leaked, NONE had stripped hardware, NONE had hard-to-remove covers/washers, ALL were assembled using new gaskets, new washers, and new Nylok nuts."
