I'm working on my engine in an unheated garage. I put it together back in July when the temps was 80* or so. Yesterday I checked the bearings and it was 45* when I bolted it back together. Will the colder temp have any effect on it? Thanks

I'm no pro but i'm gona guess maybe....i know it makes a little difference with head gaskets. Might try indexing the head of the nuts, back off and re-torque and see if they end up in the same place.

Hello????

Well...is this question to stupid to answer or no one want's to talk to me?:)Unsure At any rate....with no other come backs, I'll assume it doesn't make any difference. Hope I'm right.:dunno:

Long ago, but....

Thanks Bob, but I was hoping that some one el........LOL:D:)sphss J/K

Seriously...so the mics like to be warm and comfy and the torque wrench doesn't care either way?

It's been a long time, but I seem to remember 2 1/2 millionths, (.00000025) expansion/contraction per degree. I really doubt many of us have the capability to measure even a 50 degree difference....

Not so much the mics like being warm and comfy. Its that they are calibrated a room temperatures. But the most important is that everything you are measuring is at the same temp as the instruments.

With the mics, I got to thinking that a while back there was a topic on them and I think Steel said that your body heat can change their measurement so hold them on the plastic insert only.

Moneypit....thanks. I don't think that little bit will make any difference in my torque values.

For clairification.... I was checking my bearings for wear. When I assembled it, I checked the clearances. With the trouble I had last year with tearing up bearings, I just wanted to make sure they still looked like bearings. Everything looked good, so I bolted it back together. Just wanted to make sure the torque in the colder temp was going to be ok.

Thanks to those who posted.
