The standard torque values are clean and dry. Some applications specify
oiled, if they don't then they should be dry. The difference is a 25-30%
reduction in torque values if you oil them - unless of course it is
specifically stated to oil them in which case they have already taken it
into account. I have never seen a workshop manual which states that all
torque values are for oiled threads, so I'd appreciate it if you could send
me a reverence.

 

I believe the original question was about big end rod bolts and I believe
(without looking) the torque is specified as oiled.

 

The 1x2 is a vanity call, 1x2 and 2x1 calls disappeared here in the south a
long, long time ago. Previously I was N8KTZ and KQ4NO.

Dunno where you got your experience    :-)           but every auto repair
manual  I've read specified clean, lightly oiled bolt threads, with the
usual exception being spark plugs because they're pre-lubricated.

BTW;  how did you luck into that 1x2 call sign?

I'm not sure of the original premise, my experience is that torque specs are
given as dry clean threads unless stated otherwise. The addition of Loctite
or lubricant requires a reduction in torque or the fastener will be
over-stressed.

But can oiled threads be locked with loctite.

Torque specs are usually given for oiled threads.
