Do you really put 51 ft/lb on your oil tank drain bolt?

Pete,
yes yes I saw it. That's why I said I remember 31 and 51 but I can't remember which is which, and I did change the torque last night. Still, I think 51 on the engine case is some what too much. I gave it only 45 last night.

oil plugs
waiting for a friend to get back to me but found this.

John,
you can subscribe inexpensively to Alldata.com, they have torque setting info and they also have Porsche service bulletins (including for example a revision of oil drain plug torque settings down to 37 ft-lbs).
the case is 40 foot pounds
the tank is 37 foot pounds
will get back to the specific service bulletin if he can dig it up.

To take post #5 a bit further...
Porsche Technical Specifications book, page 58, 1982/83 edition:
Drain plug for oil screen cover = 42 Nm
Drain plug for oil tank = 42 Nm
Drain plug for crankcase ('83.5 >) = 70 Nm
Porsche Technical Specifications book, page 63, 1984-'87 edition:
Drain plug for oil tank = 42 Nm
Drain plug for crankcase = 70 Nm
Porsche Technical Specifications book, page 104, 911 C2/C4 edition:
Drain plug for crankcase = 70 Nm
Same book, page 108, Drain plug on thermostat housing = 44 Nm
70 Nm = 51 lb/ft
44 Nm = 32 lb/ft
42 Nm = 30 lb/ft
This, as they say, is from the horse's mouth...if a bulletin revising the above specs exists I am not aware of it.
