My truck is leaking a little oil, it appears its coming from the oil pan (possibly upper oil pan), all the bolts meet the torque spec (9.5ft lbs, 114in/lbs), should I try to add a 1/4 turn (or another ft/lb etc) or is that asking for trouble. They are small (m6x1) and threaded into Aluminum......
It's doubtful that you'll overtorque it by doing that, but a little snugging shouldn't be a bad thing.
Too many variables to know if it will help though. Is it a steel pan or cast aluminum? silicone/shim gasket or cork or paper?
Usually a cast aluminum pan it might help since the pan is rigid enough to stay flat as you add a bit more torque. They often have silicone gaskets which are also really good at conforming to imperfections. But if you have, for instance, a stamped steel pan with a rubber/cork/paper gasket, you could make it worse. It would just deform the pan rail.
If it's leaking enough that you want to fix it, I guess you have nothing to lose. You either re-gasket, or you try a bit more torque and the worst case scenario is you make it worse... and re-gasket anyway.

I should have given more info your right!
Stamped steel pan (lower), aluminum (upper) which is really like a windage tray kinda it looks like. I believe its O ring type gaskets.
As far as my reading says...... Pan cant fit out wo/ pulling engine... Or lifting it a few inches at least.
Picture I could find of installing the upper pan on a block.
Fix it right, fix it once. Wait till your next oil change and drain overnight prior to repair.
More torque wont fix it...might slow it down...or you could be drilling/tapping bolts with a warped pan.

I realize this is the correct answer.... But, like I said its engine out to do the pan, not going to happen for a tiny leak. Also it may be coming from the bed plate, its hard to tell so I was hoping to try to eliminate the pan.
