Changing the oil pan gasket on 2014 3.6L

I notice a minor leak coming from the oil pan gasket, so I'm wanting to change it. I found the torque spec of 96inlbs for the oil pan bolts, and that there is no gasket, and just RTV. My last questions is what is the tightening pattern for the bolts? Or is it just do skip every other one of two bolts while tightening? Thank you!

I would first make sure they are at spec before tearing into the job. You might save yourself the trouble.

For the pattern, 4 corners at 50in# then center out at 50in# then up it to 75in# center out then I like to leave it dry overnight and then go to 96in# the next day and then add fluid.

Here are the instructions from the Factory Service Manual:


Clean the upper and lower oil pan mating faces with isopropyl alcohol in preparation for sealant application.
CAUTION:
Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Mopar® Threebond Engine RTV Sealant may result in engine fluid leakage.

CAUTION:
Following the application of Mopar® Threebond Engine RTV Sealant to the gasket surfaces, the components must be assembled within 20 minutes and the attaching fasteners must be tightened to specification within 45 minutes. Prolonged exposure to the air prior to assembly may result in engine fluid leakage.
Apply a 2 to 3 mm wide bead of Mopar® Threebond Engine RTV Sealant (1) to the lower oil pan as shown.




Install two studs (2) into the upper oil pan flange.



Install the lower oil pan (1) to the upper oil pan with twelve bolts (4) and two nuts (3) tightened to 11 N·m (97 in. lbs.).



CAUTION:
Following assembly, the Mopar® Threebond Engine RTV Sealant must be allowed to dry for 45 minutes prior to adding oil and engine operation. Premature exposure to oil prior to drying may result in engine fluid leakage.

If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level (Refer to 09 - Engine/Lubrication/OIL - Standard Procedure)



Start and run the engine until it reaches normal operating temperature.
