Oil Leak

[FXRSPHD]

I have a 1995 2.2 Camry with 225,000 on her. She's leaking oil from the rear of the engine drive shaft corner. I took the inspection cover off, the fly wheel and converter are dry. there is no oil in the inspection cover pan. I replaced the oil pan gasket. I was told it might be a galley plug. The smoke from this oil whipping up on the engine is killing me. Any ideas ?
How hard is it to take this engine out? Do I have to drop the cradle? Do I have to drop the cradle to remove the transmission in order to get to the rear of this engine.

The compression and everything is great on this car. Car looks like new. My grandfather drove it for years keeping up on all the maintenance.

With the amount of miles that you have on the car you may have the following problems 1st is the distributer o-ring 2nd is the valve cover gasket. I realy needed to know if it is a v6 or 4cyl ? On the valve cover there is small half moon cut outs you may want to remove the aluminum moons and clean and reseal with Toyota FIPG ( form in place gasket the after market equivalent is black silicon RTV ) that will take care of the easy stuff. As for removing the engine I would not unless the rear main seal is leaking. You also said that you replaced the pan gasket well got news for you it soud not have a cork or paper gasket this also should be sealed with Toyotas FIPG. Now if all that is good that leaves seals and o-rings under the timing belt there are cam seal or seals, crank seal, oil pump seal ( 4cyl only ) this also has a formed o-ring behined oil front cover. PLEASE KEEP ME UP ON WHAT GOING ON!!!!
