Got under the Jeep yesterday. After about 3 years since the last replacement, it's leaking. I know the 4.0 is prone to leaks, but it just go me thinking, how long should I have expected it to hold?
A couple of tricks, the bolt holes get a little cone-shaped on the pan, lightly hammer them flat. I found the composite gaskets smeared with high temp silicone on both sides to be the best, Felpro second best. Don't over tighten the bolts, a drop of Loc Tite will keep them from backing out. If the gasket shrinks the bolts may loosen (without the Loc Tite). If you overtighten the bolts on some gaskets you can split the gasket.
Also, if using silicon which tends to shrink as it cures, I very barely snug the bolts at first. Let it sit for a bit and setup a little harder and then do the final torque.
Yes. Had to hammer mine flatA couple of tricks, the bolt holes get a little cone-shaped on the pan, lightly hammer them flat.
