is something missing?

Is there supposes to be somethint between the plate in front of the bellhouseing and the bellhousing itself? When I get done driving it smells of gear oil and there's oil dripping from the bottom of the truck. Just wondering if that's normal

Nope.
You sure it's gear oil and not motor oil?

Could be motor oil from the rear main. That is common with these. I replaced most of the gaskets on mine last year. Rear main included.
No more leaky.

Good Luck.

Correct. No seal there. But read this first before tackling the rear main:




I'd be looking up ABOVE first, and VERIFYING the source of the oil leak YOURSELF.

Everybody, who doesn't own or have to pay for or perform your vehicle repairs, loves to poke their noggin UNDER the Jeep and come out bearing the false bad news that your RMS is leaking.

Many mechanics, friends, and good old Uncle Bob seem to enjoy telling you it’s the rear main seal. Has a catastrophic ring to it, doesn’t it?

A simple leak at the back of the valve cover or other source could produce the same symptoms. You don’t need to be a mechanic to figure this out. If you have good eyesight and a dim flashlight, you’re good to go on your own. Don't jump on the RMS/oil pan gasket bandwagon right off the bat.

Almost any oil leak on your 4.0 is gonna drip from the RMS area for two simple reasons.

First off, the engine sits nose-up and any oil will run back to the RMS area. Secondly, the RMS area is also the lowest point on the engine. Simple physics and the old plumber's adage apply here. "***** flows downhill".

Valve cover gasket, oil pressure sending unit, oil filter adapter seals and distributor gasket, in that order, have to be eliminated as possibilities first.

Yes it would, but it was a slow leak.

Then my queston is:
If it was a SLOW leak, how come you ran out of oil? Never check it?

You're not getting of that easy. Checking your oil using the dipstick has nothing to do with what your oil pressure gauge is reading or road conditions. Oil gauge is only indicative of pressure, not level.
