engine torquing specs in cold climate

[krobb]

Hi,
I need to rebuild my engine (1970 911T Targa). The problem is, I live in a cold climate and my garage is not heated (and I would not attempt to heat it). It gets really cold some times (10 deg. Farenheit or lower). However, there are days when the temp can be a bit warmer (32 deg to 50 deg F). The spring time can be 41 deg to 60 deg F and the summer can be 60 deg F to 86 deg F. My question is when can I put the engine back together (in terms of the seasonal temperature)? I would think that puting it back together when it is cold may put more stress on the fasteners when the seasonal temperature warms up making all the fasteners over torqued. Also, would there be a problem taking the engine apart in the cold?
Thanks

How nice is your wife?
I wouldn't think it would be a problem taking it apart in the cold. I doubt you would have any problems in any temp though. No more than one that is tourqued down in my garage in the summer around 100 deg f and then driven up north and left outside in below zero.
Might be a moot point anyway with global warming

I don't think there will be much difference on torque values. When I work on my car in winter I use an electric space heater to heat the area I'm in so I don't freeze. A space heater directed at the motor while working will warm it up some.

The only thing you might notice is a tighter fit of the wrist pins in the pistons. You can overcome that by heating the pistons with a propane torch.

Frightening idea. Surely heating them in an oil bath would be a bit more controlled

An oil bath sounds messy.
