Oil pan bolts are torqued in inch lbs due to their size and usually doesn't require a specific torque value. all bolts in a manual does show torque settings in all applications.However because of its non critical application a specific value is not necessary. a "snug" tightness is adequate with proper gasket/sealer in place to prevent seepage or leaks. in that area of the engine,leak can come from almost anywhere. top,front,or even rear of the engine blown by the wind a car creates while in motion. oil sensors{ but not limited to} are notorious for leaks as the vehicle ages particularly in that area. steam clean or thoroughly degrease the area and run the engine a few miles and recheck the area before proceeding to make repairs.

SOURCE: Need torque specs for oil pan gasket

There likely is a spec for oil pan but unless you are a finatic, you really don't need to know what it is. Simple rule: Don't crank down ******* any fastener. If corners near crank ends have larger fasteners, you can tighten them a bit more than on siderails. Before tightening anything, install all bolts finger tight, to ensure that they are not cross threaded. To avoid warping pan, tighten from the center of the pan, working towards both ends, alternating from side to side as you go. When you are finished, go over it again, using the same amount of force on each bolt. As I said, end bolts can if larger in diameter, be tightened more but be careful not to tighten so much that you will either split or push the gasket out the sides.. Anywhere two gasket ends **** together, I recommend using a sensor -safe dab of silicone. An oil pan is not under any mechanical stress or pressure. I have used this method for many years and NEVER had one leak. If you really need #s, small fasteners get about 12-15in lbs, larger ones about 20.

Do you need to torque oil pan bolts?
Engine oil pan bolts range in torque from seven foot-pounds to 22 ft-lb or more for large engines with heavier pans and bolts. Once you've torqued the bolts and filled the engine with oil, you should run the engine for five minutes to bring it up to normal operating temperature.

How to replace an oil pan gasket on a toyota corrolla 2007?

remove anything in the way of the oil pan that won`t allow it to be lowered. drain the oil, then remove the oil pan holding bolts and you might have to hit the oil pan to get it loose and lower the pan. clean surfaces on the motor and oil pan of gasket material and oil on the gasket matting surfaces install new gasket to pan and install. torque the bolts to 10ft lbs torque I think or until the bolts are tight but the gasket is not being pushed out from between two surfaces.

It's a direct shot....

Removal & Installation
  1. Disconnect the negative battery cable. Raise and safely support the vehicle.
  2. Drain the engine oil into a suitable container.
    1. Remove the transaxle converter cover.
  3. For 1986-90 vehicles, remove the starter motor from the vehicle, as outlined in Section 2.
  4. Remove the oil filter.
  5. If equipped, disconnect the oil level sensor.
  6. For 1996-99 vehicles, remove the oil level sensor. On these vehicles, the oil level sensor must be removed prior to removing the pan. If the pan is removed first, damage to the sensor may occur.
  7. Remove the oil pan-to-engine bolts and the oil pan. Remove and discard the oil pan gasket. The formed rubber oil pan gasket cannot be reused.
  8. If necessary, remove the oil pump pipe and screen.
  9. Thoroughly clean the gasket mounting surfaces.
To install:
  1. If removed, install the oil pump pipe and screen. Secure with the retaining bolt(s) and tighten to 89 inch lbs. (10 Nm).
  2. Place a new formed rubber gasket in the oil pan flange.
  3. Position the oil pan and secure with the oil pan-to-engine bolts. Tighten the bolts to 124 inch lbs. (14 Nm). Do NOT overtighten the bolts, as this will damage the oil pan, causing a leak.
  4. For 1986-90 vehicles, install the starter motor and transaxle converter cover.
  5. Install a new oil filter.
  6. For 1996-99 vehicles, install the oil level sensor.
  7. If equipped, connect the low oil level sensor wire.
